Secrets

  • Blow Up Earth and God Mode

    Start the level Area 51. Next, upgrade the remote mines to the highest level, and lay them next to the crashed saucer in the corner of the level. Go to the middle of the level and use the teleport to get up to the moon. Once on the moon, detonate the mine. The earth will then blow up in a huge explosion. Afterwards, fragments of the earth will crash into the moon and make it explode too, and you will be stuck out in the middle of space. You will have full health and weapons out in space, but nothing to do with them. Quit the level and start another and God Mode will still be activated with all weapons and invincibility.

  • Secret Area in Quake-A-Roni

    Once fighting in Quake-A-Roni, you may see a building that seems to be tilting in one direction. Fire a few missles at it and watch it blow. Once that is over, notice a building nearby has a hole in it. Now drive through where there's a few weapon pick-ups and a monument to blow up.
