    This walkthorough is intended to help anyone solve the Still Alive Challenge 
    Maps. At the time of the first writing, I did not intend to give tips on 
    Least Portals, Least Footsteps, or Fastest Time. Now I have added sections
    for these acheivements. If anyone has tips on these and would like to help
    make this walkthrough better, please send your ideas by sending them to me
    (paul82471(at)hotmail(dawt)com) and I will give you full credit.

    Proceeed to the moving platform and ride it to other side of the Acid Pool.
    Step on the button to open the door. Shoot a portal to the right or on the
    floor of the rrom you can now see. Just don't place a portal straight ahead
    or you will get hit with a Energy Ball when you go through the portal. Ride
    the platform back and place another portal and step thorugh to the other room.
    
    In this room, place a blue portal where the Energy Ball is bouncing off the
    wall and an orange portal up on the wall facing the door to the Energy Ball
    Reciever. As soon as the ball goes thorugh, place a portal above the platform
    with the button and one at your feet to get to the button and let the Energy
    Ball get to the reciever. Now exit thorugh the door you just opened.
    
    ***************************************
    * Still Alive Challenge Map 2 - SACM2 *
    ***************************************
    As you enter the room, to your right is a glass wall with a small square hole.
    Shoot a blue portal through that hole and an orange portal anywhere in this
    room and step through. Now place a blue portal directly below the Energy Ball
    Reciever and step through it to return to the first room. Place an orange
    portal on the floor where to Energy Ball hits.
    On the far left corner as you first entered this room, there is a hole in the
    ceiling marked with the number 2 die. Look up this hole and you can place a
    portal on the ceiling up there and be able to fall onto a ledge as you are
    falling through. Once you are on the ledge, you can shoot a portal throgh two
    small square holes. Fall back down to the first room and portal thorugh to the
    portal you just shot through the squares. Now just walk through to the end of
    the level.
    
    ***************************************
    * Still Alive Challenge Map 3 - SACM3 *
    ***************************************
    
    As you first enter this level, you will have a button. When you press this
    button, it will destroy the cube on the button and cause the door to the next
    room to open, I know it's ass backwards ain't it. When you push that button,
    you will have just enough time to run around to the door and place a portal
    in the next room. Then you can portal into that room.
    Now get on the platform and go to the next room. When get into this room just
    walk straight into the room to your left. Turn left and shoot a blue portal
    through the small square hole in to the room you just left. Then place an
    orange portal on the only wall in this room you can now, the wall at the
    ledges. Now portal back to the room, DO NOT walk thorugh the door with the
    Energy Field or your portals will disappear. Pick up the cube and portal back
    and use the cube to climb the ledges up to a button. Place the cube on the
    button. Before you get back down off the ledges, place a blue portal in the room
    that you just opened the door to. Climb down and portal up to the room and
    shoot an orange portal throught the small square hole here to the first room.
    Go through and place an orange portal closer to the floor. Now press the
    button and pick up new cube and portal back. Place the cube on the button and
    portal back to the first room and walk through the door to the room with the
    ledges and then exit the level.
    
    ***************************************
    * Still Alive Challenge Map 4 - SACM4 *
    ***************************************
    As you enter this level you will se the room has two small square holes, one
    that shows you the exit and another that you can only see a wall. Shoot a blue
    portal through the hole with just the wall and an orange portal on any wall
    here. Pick up the cube and portal through to place the cube on a button. Now
    portal back to the main room. As you entered this room, if you walked to the
    cube drop button and turned left and looked up, you can see a ledge. Place a
    blue portal on the ceiling of that ledge and portal up there. Stand on the
    button here and look across to see the door you just opened. Place a blue
    portal on the wall next to the button in the new room. Now drop back down and
    press the button to get a new cube. Pick up the cube and portal to the new
    button. Place the cube on the button and drop off the ledge here to reach the
    exit to the level.
    
    ***************************************
    * Still Alive Challenge Map 5 - SACM5 *
    ***************************************
    
    As enter this level you have a cube sitting on an electrical grid. Just wait
    for the electricity to turn off and run grab the cube and come back. Put the
    cube on the button and go through the electrical grid again to reach the next
    room.
    In here, you have a couple cube on top of an electrified ledge. Place a portal
    an one of the walls to the side of the ledge. The walls are 3 blacks high, I
    placed mine in the middle block and even with one of the cubes. Goto the
    dropoff at the entrance to the room and place the other portal down on the
    floor below and time it so when you portal, you won't get electrocuted. Do the
    same for both blocks and place them on the buttons at the end of the room. Now
    the exit is open, but getting there is tricky.
    Above the entrance to the room, a panel just shifted out at an angle. Place a
    portal on the floor of the dropoff you used to get the cubes. Then place a
    portal on the ceiling above. As you drop through the ceiling portal, try to
    place a portal on the angled panel. This is about luck, cause I can't figure
    a way to time this so you don't get electrocuted. When you are sucessful, you
    will fly across to the ledge to the exit.
    
    
    ***************************************
    * Still Alive Challenge Map 6 - SACM6 *
    ***************************************
    
    As you enter this level, there will be a malfuncing door, just give it a
    minute and it will open slowly and you can walk in.
    Don't walk into the laser beams, DUH! Just portal into the next room. Once
    in that room look up. Portal up to the ledge there. Now portal up once more
    and walk through to the next room. You cannot walk on the red light bridges,
    only the white ones. You can shoot a portal through them, so walk to the edge
    and look down. You will see a small ledge that you can portal to. Get there.
    On this ledge look up and to the right and you will see wall you can portal to
    in another area. Once up there, around the corner is a dropoff. Place a portal
    above the first ledge you were on and one on the floor of the dropoff to drop
    into and you will shoot across over the red light bridge. WHOA! We almost hit
    a laser. Shoot a portal through the laser door and drop to that ledge you
    first portaled to and place another portal and step through to the next room.
    Here's another laser door. Just portal around it.
    Walk forward to the red light bridge and portal down to the button. Look up
    and you'll see a ledge, this leads to a door that this button opens. Place a
    blue portal on the wall across from the ledge and an orange portal right next
    to the button you are standing on. As you walk thruogh the portal shoot a blue
    portal through the door as it is closing and you will drop back to the button.
    Walk through the orange portal to get to the next room.
    Just walk across this light bridge and portal into the room with the cube drop
    button.
    Look straight up, you can see that turret right. I know, I hate them too.
    Press the button to get a cube and portal up to the next level. Pay attention
    to which side the turret is on when you portal and use your cube as a shield
    as you make your way to the side opposite the turret. You can get behind a
    wall here and look up to portal to the level the turret is on. Crouch behind
    your cube and walk to the turret to knock it over. Now take the cube back to
    button and place it on there.
    Walk back across the light bridge to the glass wall that was behind the turret
    and look down to place a blue portal to another level. Use an Orange portal
    back where the button is to get there. Once through, you will be on a light
    bridge. Shoot a blue portal through it to get another level down. Walk across
    the electric field and look down to place a portal to the side of the turret.
    Go back to the other side of the electric field and portal there. Pick up the
    turret and drop it in the acid for an achievement.
    Walk through the open door, turn right and goto the far wall. Look back and up
    and place a portal as far up as you can. Place another portal on the wall
    beside you. If you look through, you can see a wall you can portal through the
    light wall there. Just step through and shoot the partal across as you fall
    back down. THERE IS TURRET RIGHT IN FRONT OF THE PORTAL YOU JUST MADE. It is
    close enough to the portal that you can run through and get to the side of it.
    Grab the turret and drop it off the ledge.
    Look straight across and slightly down and there is a 3 block wall. Put a
    portal in the middle block. Then place a portal straight down from you on the
    floor. Barely walk off the ledge to fall into this portal and you will shoot
    out to another ledge that is below you.
    Walk through the door and you will see 3 lasers from 3 turrets. Walk to your
    right and drop to the floor below you. The turrets cannot shoot you down here.
    Walk to where you are below the turrets and look on the wall their lasers are
    pointing. There is a block of white wall at the very top of that wall. Put a
    portal there. Now goto that side of the room and place a portal on the floor.
    When you go through the portal fall to your right so you fall off the light
    bridge and shoot a portal on the floor as you are falling so you shoot out of
    the first portal to where the turrets are. You will either go over them or
    knock them down.
    Now you can exit the level.
    
    ***************************************
    * Still Alive Challenge Map 7 - SACM7 *
    ***************************************
    
    In the first room, you have a red light bridge over two buttons. You can walk
    across on the sides of the bridge or play it safe and portal across.
    Once across you will see a light door to another room. Shoot a portal into
    that on the floor, not on the platform or a cube will fall and kill you.
    Grab the cube that falls and portal back into the first room to place it on
    one of the buttons, doesn't matter which.
    Portal back into the second room and look up. You will see a wall you can
    place a prtal on the side of the room with the light door. Place one there
    that is even wiht the platform. Now place a portal right under that one so you
    keep falling thorugh. As you are falling, Place a portal right under the cube
    chute on the platform. When you hit it right, you will be shot up into the
    cube chute.
    Once in the chute, You'll see a small square holle you can shoot a portal
    through to a wall. Then drop back out of the chute and portal to the new room.
    Walk around and open the door. Look up and you'll see a grated floor. Shoot a
    portal through it, not above the square hole in the grid. The portal up there.
    Open the door and clicmb into the tube with a hole in it. Crouch and walk to
    your left until you drop. You will drop on top of the remaining cubes in the
    chute and cause them to fall out.
    Fall down with them and portal inot the first room while carrying one of the
    cubes and place it on the other button then exit the level.
    
    ***************************************
    * Still Alive Challenge Map 8 - SACM8 *
    ***************************************
    
    When you walk through the door at the beginning of this level, IMMEDIATELY
    turn left and run. There is a turret on a platform trying to kill you. When
    you get beside the platform, place a portal to the side of the platform and
    another down near the floor so you can jump in and be behind the turret. Then
    grab the turret and throw it down.
    Go to the end of this room, turn around and look up. There is a place on the
    ceiling over the highest ledge that you can place a portal. Do that and portal
    up there. You will find a button here, press it and a ball falls from a chute
    on another ledge across from you. Wait for the ball to roll down to the floor
    and jump down yourself.
    Now grab the ball and portal back to the same ledge. Just below the ledge the
    ball fell from, there is a panel sticking out at an angle. Put one portal
    there and another one on the floor near the ledge your on. Now drop the ball
    into the portal on the floor. The ball will shoot across the room and hit the
    turret below you.
    Now if the ball stayed on that ledge after hitting the turret, just follow it
    and then place it on the button at the end of the hall there. If not you will
    have to retrieve it and portal back to where you are to do that.
    Now turn around and you will see the checkmark across the room. Put a portal
    right above that and drop down to the floor to place another portal so you
    can portal there. You will fall down to the exit of this level.
    
    **************************************
    * Still Alive Challenge Map 9 -SACM9 *
    **************************************
    
    At the beginning of this level, you will see an energy ball bouncing from the
    floor to the ceiling. Walk on the side of the light bridge over the energy
    ball thrower to get to the other side. Turn around and look up, and you will
    see a laser from a turret. Put a blue portal on the wall the laser is hitting
    and an orange portal on the ceiling where the energy ball is bouncing off. 
    The energy ball will take out the turret for you.
    Now goto the other side of the light bridge and place an orange portal on the
    wall and portal up to the ledge. Portal across the opening and go down the
    hall here.
    To the left, look up and there is another laser. The turret will be on the
    side that has the cube chute. Put a portal on the back wall there and portal
    there to fall behind the turret and take it out.
    Grab the cube and fall back down to go to the other side and drop the cube on
    the button there.
    Now portal back up to where the cube chute is. If you stand on the button, you
    will see what we have to do here. To get the energy ball up here, put a blue
    portal right behind the button here, drop down and get where you can see where
    the energy ball is hitting the ceiling. You want to put an orange portal there
    and as soon as it comes through the portal, shoot a blue portal on the side
    wall of the ledge that has the cube chute. Then put an orange portal down near
    you so you can portal up there. Watch through the portal and as soon as the
    energy ball goes by from right to left, portal through and step on the button.
    Now while still standing on the button, you will se right across from you a
    wall you can portal to. Do that, but THERE IS A TURRET THERE. So as soon you
    land run past the turret.
    There you can exit the level.
    
    *****************************************
    * Still Alive Challenge Map 10 - SACM10 *
    *****************************************
    
    As you enter the first room here, you see two buttons. Walk out a ways and
    turn around and look up. Put a portal on the panel above the door you came
    in. Now place a portal on the wall near you and look thorugh the portal.
    Across the room, you can see a smare square hole above the cube. What you
    want to do is place your crosshairs on that square and slowly walk into the
    portal until the portal indicator on your crosshairs are active. When you can,
    shoot a portal through the hole and you will drop down to the floor.
    Now just walk through the portal you have down here.
    Your now standing on a light bridge. If you look down you can see the exit to
    the level, but we can't get there yet. Look up and you'll see a small ledge
    and an electric grid. Put a portal to the side of the electric grid and
    another near you. Slowly walk through onto the small ledge and when the grid
    cuts off, run down the hall and to the right.
    When you get to safety, across the grid is another smal square hole. Shoot a
    portal through there and portal over there.
    Climb up the blocks to the ledge here and you will see a red light bridge.
    Go along the side of the bridge and on the other side put a portal on the wall
    behind the button. Now look down at the light bridge and you will see a cube.
    Shoot a portal on the floor there right beside the cube and the cube will fall
    thorugh to the button. That opens a door beside the button. Go there and put
    a portal on the wall over the door you first came in on this level. If it's
    not already one there, put a portal on the wall behind the button and pick up
    the dube and portal into the first room. Put the cube on one of the buttons.
    As you first walked in the door, you may have noticed the button sitting on
    the ledge straight up from the buttons. In order to get there we have to get
    up some speed.
    Right to the right and left of the door, on the ceiling are places you put a
    portal. Pick which side and put one there. Then put another portal on the
    ground directly under that one. Now as you fall through the portal, shoot a
    portal the same color as the one on the ceiling on the panel above the door.
    This took me some time, but wasn;t too tough. You should shoot out across the
    room to the ledge the cube is on. Grab the cube, drop down, put it on the
    other button and jump across to exit the level. 
    
    *****************************************
    * Still Alive Challenge Map 11 - SACM11 *
    *****************************************
    
    As you walk to the first door here, look up. You see those sharp pointy tiles
    on the ceiling. It's like that cause the ceiling is going to come down on you
    as soon as you drop to the floor here. There is no reason for you to drop to
    the floor, just portal across the acid pool.
    Go to the next room and as soon as you get there, run across to the opening in
    the wall straight across from the door. The ceiling will come down, when it
    does step on top of it.
    The ceiling is now an elevator for you and you will see as you go up a wall
    that divides this room and the next. You can jump across to the other room.
    Hop over to the other room and go straight to shoot a portal through the
    square hole in the glass wall. Then put a portal at your feet on the floor and
    portal to the next room.
    Now here we go with another killer ceiling. Before the ceiling comes down too
    far, put a portal up a ways on a wall here. Then put another portal on the
    wall next to you. When the ceiling clears the top portal, step through and you
    will be on the top of the crusher. On the way back up, you will see a glass
    wall with a square hole. Shoot a portal through the hole and another on the
    wall as you go up. Step through and we're done with the crushers.
    Move into the next room and you will see a hydrulic ram through a door. Place
    a blue portal next to the door. Wait for the ram to clear the door, then run
    down the hall and place an orange portal at the end and go thorugh to return
    to the original door. This way you always have a way out. Continue placing
    orange portals at the end of each ram and running down the halls until you get
    to a glass all on your left with a square hole in it. If you want to play it
    safe, just walk through a portal at the end of the hall like the others. If
    you feel adventurous, shoot a portal at the end of the hall as you are running
    and shoot another portal through the hole when you get to it. Once you portal,
    you will be at the end of the level.
    
    *****************************************
    * Still Alive Challenge Map 12 - SACM12 *
    *****************************************
    
    As soon as you walk thruogh the door at the beginning of this level, walk to
    your right. Not too far though. You have two turrets in this room. One is on
    the same level as you, the other is on a ledge. Let's get rid of the one on
    the ledge first.
    Put a portal behind it to the right. You can do this without it seeing you.
    Portal through and knock it down. Now walk toward the front of this ledge to
    the left and get an angle so you can put a portal to the right of the other
    turret. Portal through and knock it down.
    As you can tell, we need two cubes here for these buttons. One is on a shelf
    way up to the left as you entered this room. We need to get the other one to
    help us get the one on the shelf.
    Go down the hallway that is up on the ledge the first turret was. You will see
    the cube through a glass wal, but we can't climb to it. If you look on the
    wall opposite the ledge that the cube is on, there is a wall panel you can put
    a portal, do that. Go back to the other room and put a portal on the floor in
    front of the ledge and fall in. Now you can get the cube.
    Return to the first room and as you are standing on the ledge the first turret
    was on, there is a lift directly in front of you. Portal up there with the
    cube. Look to your right and you will see a button on a platform with a
    ceiling panel above it. Put a portal on that panel and another behind you on
    the platform and drop the cube through so it lands on the button. Now the
    platform you're on will raise.
    Shoot a portal on the floor in front of the shelf that has the other cube.
    A good reference point for this is right up against the wall under the up
    arrow sign.Then walk in that direction off the platform and shoot another
    portal on the floor as you fall to be thrown up to the shelf. Grab the cube
    and fall down. Put the cube on a button, portal up to the other cube and put
    it on the other button.
    Now portal up the ledge and walk through the door. Go down the hallway to the
    other door. Whoops, we got a malfunctioning door. No problem, just aim your
    portal through the crack between the doors and shoot a blue portal, and an
    orange portal on the wall beside you, but DON'T just portal in. If you look
    in the portal, there is a laser beam. We know what that means.
    Real quick, go through the portal, look right, and shoot an orange portal on
    the wall behind the turret and duck back into the blue portal. Now you are
    free to take out the turret.
    Walk to the end of this ledge but be sure to drop off to the left. There are
    two turrets directly below you here and they are cleaverly facing each other
    so you can't see their lasers.
    Once you have fallen you can creep up and get one of the turrets without a
    problem. To get the other one, you will have to move out of cover from the
    corner, shoot a portal behind it, and move back into cover. Then you can
    portal behind it and take it out.
    Starting from where that last turret was, go down the hallway and turn left.
    Go to the end and look up. Shoot a portal as high up on the end wall as you
    can. Then go back down the hallway and turn left to goto the dropoff. Put
    a portal on the floor on the lower level here. If you look into the portal,
    you can see there is an electrical grid on the other side, so time your drop
    so you don't get fried and run across the grid.
    Now turn around and look up. Put a portal on the ceiling above the ledge over
    the electrical grid. Portal up there and you see you can get the cube, but
    don't drop down yet cause we can't get out of here with it without some prep-
    work.
    As you are standing on the ledge looking at the cube, turn to your ight and
    place a blue portal on the wall at this level. Now go back to the red light
    bridge and shoot an orange portal on the same level as the grid. Portal down
    and run across the grid and drop down another level. Shoot an orange portal
    on a wall here. Portal bcak to the ledge over the cube, drop off the ledge,
    and put a blue portal on a wall here. Then pick up the cube and portal back
    down and place the cube on the button down here.
    From the button, go around the corner and look left and up. You will see a
    wall panel across from a ledge. Put a portal on the wall panel and another
    portal on the floor of the dropoff here and fall into the portal to cross
    over to the exit of this level.

    In the first room of this level, look up and you will see a white light bridge
    with a cube sitting on it. Shoot a portal on a wall through the light bridge
    to grab the cube and come back down. Now look up on the side of the room and
    you'll see a ledge with a red "X" on the ceiling. That red X has a turret up
    under it, so shoot a portal behind it on the ceiling and take your cube up
    there with you. Take out the turret.
    Now, get on the lift, crouch, and have your cube facing toward your left.
    There is a turret here and your cube will be your shield. When the lift gets
    to the top, just strafe left and you will be in the rrom with a button. Push
    the button and an energy ball will knock over the turret.
    You will see where the energy ball came from, a little "chute" in the wall.
    Grab your cube again and use it to deflect an energy ball in to the energy
    ball reciever across from you.
    Now take your cube and crawl down that "chute" to the other side and drop down
    and you will see a button. Lay your cube on the button and place a portal on
    the wall next to it.
    Before you drop down this ledge, notice there is a turret there. Drop down and
    run to the side of the turret real quick, then take it down.
    Go into the the turret was defending and put a portal on the wall in there. Go
    through and get your cube and place it on the button in the room. This will
    open the door above the acid pool.
    If you stand near the acid pool icon on the floor, you get an angle to see a
    wall down the way that you can put a portal on. Put one on there and look
    through it. You will see a platform that is raising and lowering into the acid
    pool. Ease into the portal and look right. You can see another wall for a
    portal but there is also a laser. In order to get there, you will wait for
    the platform, walk out onto it, shoot the portal, then go back in. Remember,
    if you walk through a blue portal, shoot a blue portal.
    Be sure to put your portal on the left hand panel of the wall so you can hide
    around the corner from the turret.
    Getting the turret is easy. Just hide around the corner, strafe left shoot a
    portal to the right of it, and strafe right. Then portal over and knock it off.
    Now look to the left and you will see another platform beside another turret.
    Just put a portal on the wall above the platform and wait for it to come up
    and run through the portal and beside the turret. Now take it out.
    Now look straight down the hallway and you'll see another platform. Put a
    portal on the wall above it, preferably on the right side of it. When you look
    through the portal you will see a ledge down the hall that you can portal to.
    Just like before, walk onto the platform, shoot the portal walk back into the
    portal. Remember, if you walk into a blue portal, shoot a blue portal.
    Now you will have a moving platform going from right to left. Jump on and ride
    it to the first of two turrets down this hallway. Jump off to the left real
    quick when you reach the turret and get behind it to take it out.
    Do the same for the next turret.
    Now just ride the platform to the end of the acid pool and enter the next room
    There is button here that controls a door at the end of the hallway on the
    ledge. Portal up to the ledge, and follow the hallway to the door. Put a
    portal on the wall facing the door and go back to the button. Put another
    portal as close to the button as you can.
    Press the button and run through the portal and shoot a portal thorugh the
    doorway before the door closes. Now just portal into the exit for this level.

    When you first enter this level, you are on the top level of three in the
    room. You will have two cubes here with you, go ahead and drop them down to
    the second level. Before you go down to the bottom level, see that there are
    two turrets down there. One is hidden behind a stack of cubes and won't be a
    problem as long as you stay in the middle of the room.
    Drop down in the middle and turn to the turret and run beside it quickly. You
    can take it out now.
    Now to get the other turret, just use the single cube in the middle of the
    room as a shield to knock it down.
    Now the turrets are gone, look stright up and shoot a blue portal through the
    square hole in the ceiling and an orange portal on the the wall near you. Look
    through the portal cause an energy ball is bouncing back and forth in that
    room, so time your portal so you don't get hit. Once in there, stand to the
    side and put a blue portal where the ball is bouncing on the wall. Time it so
    you don't get hit, and run through the portal to go back to the floor.
    Now stack some boxes so you can get to the second level (two cubes beside the
    wall and one cube in front of them), and jump up to the second level. Place an
    orange portal on the floor of this level directly below the energy ball
    reciever.
    That opened a door right here on the second level. Shoot a portal through the
    square hole and another on a wall here. Take both cubes here through the
    portal and drop them onto the button on the floor of this room. Jump across to
    the shelf on the other side, turn around and portal down to the level the
    button is on. Put one cube on the button and shoot a portal through the square
    hole in the wall.
    Take the other cube and time your portal so you don't get fried by the grid in
    the other room. Run across the grid and drop the cube on this button. That
    will open a door above and behind you so you can portal back to the original
    room.
    Now portal back up to the room the energy ball was in, and drop two cubes into
    there. Obviously, you want to put a cube on each of the buttons here, then
    portal back to the floor. Put the last cube on the button in the middle of the
    floor. That opened a door on the floor where what should now be five checkmark
    signs are. Just drop down to reach the exit of this level.

    When you start, JUMP all the way to the platform, it will take a few tries to
    get the timing right, but jumping makes you move faster, thus you can get onto
    the platform quicker and ride over on it. Step on the button, shoot a portal
    on the wall or floor in the other room, NOT next to the energy ball. then shoot
    a portal NEAR THE ACID FLOOR (Be VERY careful not to f@*( this up) and jump
    into the portal. you just saved yourself about 1 minute of waiting on the lift,
    that should give you enough time to do the portals and beat the challenge for
    a gold metal and an achievement IF you dont have one already

    This the first walkthrough I have ever written. I have no one in particular I
    want to acknowledge, but would like to thank everyone who has written any
    walkthrough. This was not as easy as I thought it would be, and has given me
    a real respect for those who write them.
    Keep up the good work, and thank you everyone.
