Super yes it is, I purchased it two nights ago and have been playing it.
MUCH better than the first one. There are now "minigames" which are pretty much, hack this computer or hack this door. There are cut scenes which are pretty neat. One that comes to mind is you walk in a room, when a lesser hellspawn i believe it was, jumps from the celing and comes charging at you.
Now if gamefaqs would ever get around to accepting my release change, I can actually sit down and take the time to write a FAQ for this game.
This isn't out in the Verizon BREW apps in the US at least. Yes, you can download the inferior Java version and just play that, but the BREW version will have actual sounds, better animations, and smoother graphics. Can't wait for it to be officially released.
Just got the BREW version through Verizon last night (LG VX8500 chocolate). The graphics are great, sounds are great. Total app size is 2.44 MB compared to 800KB for Java. Much more content in the BREW version! Very happy with the game so far, almost reminds me of System Shock 2 :D
