I'm going to keep this short and sweet, but I wanted to take the time to inform everyone that this game is not worth playing in the least. I have a hard time finding a single iota of joy slugging through tiresome, randomized levels just to get to the exit. It's not so much the premise behind the game but rather the gameplay mechanics that were HORRIBLY designed. No online multiplayer. Can't keep your leftover money if you return to the surface. If you die, you lose all of your equipped badges and sub-weapon as well as half of your money. I could go on. This is just not worth any amount of time investment...at all. AVOID.
