Even though a good 1st person, the game does have a few bad points

Take Halo's flood and residents evils T-virus, and you'll get a good idea about what your exactly your killing in this game. The game is really fun, don't forget that, but you might want to rent it to get a good idea of what kind of shooter. The plot is pretty good, along with all those crazy guns and zombie alein people trying to rip you to little pieces or crud.
Perhaps the game could have done better if the whole alein-mutation-feature was added a little BEFORE you got used to being a human. But being a alien thing and slashing up other alein zombie things and those stupid soilder guy to busy trying to kill you while there's all these freaky things everywere.
Charater designs could have been better, but I highly suggest trying this game, before yo buy it. and its worth it. really
