Not much different here
There is an assumption that you have played the original game when you play this sequel. If not play the original because this is not very different. Basically you are in space and humans have been turned into monsters and you have to kill them to get out. Yes thats not the full story but overall thats what it is. You get a small variety of weapons and ammo and you get different outfits. These outfits give you different powers but the differences are so small you could probably just go with the most expensive outfit instead of trying out the strengths and weaknesses of all of them.
Not to keep like I am dumping on this game because it is fun. Do not get me wrong overall the game is very creepy and can be fun at times. The problem I get is that there is not much here for a sequel. Nothing is really changed and it seems to be a redo of the original game. A few new guns and suits and a few new monsters. Graphics and sound are good and they really help the creepiness.
I would say to get this game because it is probably very cheap and you can buy it as a bargain. If you have not played the first one then go play that one and if you like it go for this one. I really cannot write much about this game because there is not much to say. Its a carbon copy of the orignal without changing too much. It has the usual monsters coming out in droves then coming out fast at you thats about it. Not much has changed from the original sorry to say.
