Crap.
1. the morons who created this game
2. masochistics.
As well, here is a reason why you SHOULD play the game.
1.
The gameplay is very clunky, uninspired, and altogether boring. More or less, they send you in a series of pre carved tunnels to run around and shoot stuff. This would be mildly tolerable if it wasn't a chore. The guns are boring, the action is boring, and the overall game play is a chore. After the first two hours, I had to force myself to continue playing. The gameplay quality is among fun things to such as running your pecker through a printer. Seriously.
The graphics are, just like everything else, bland. The models are very undetailed, and most of them just look stupid. The enviorment is sparse, and you get the sense that the game was decorated by a prison warden with a small budget. While not exactly painful, it just feels like a rush job by the developers, and if I had to guess why, it would be because they were tired of the game themselves.
The sound is perhaps the high point of the game, if you have the guile to lie to yourself and others on such a scale. Like the graphics, it's bland, and very forgettable. It's difficult for me to recall much of the soundtrack as I write this, so don't be surprised if you ever play this game and the music goes in one ear and out the other. The sound effects are a little on the weak side, and so is the voicing, but the audio still the best element. Best in the same manner that it is better to get AIDS then die by being trampled to death. It still suck pretty hard.
This game very well might have decent value, but the problem is, it is fairly unplayable. If you like the pain or for some reason are in love with this game, then you might be able to squeeze 10-12 hours out of it, but otherwise you'll be in for a short ride.
In short, I do not like this game. It is not a terrible game, but I think it is a fair epithet to call it crap. I could say that with a little more polish, this game could've been good, but then I'd be lying. It's tough to find a reason even to RENT this game, much less buy it or enjoy it. Either way, you've been warned.
