This game does have a few catches too it , they did'nt really think it through well. As the previous reviews have stated the graphics arent all that good, (there not bad though, it just depends if your used to Crysis or not) , the controls are quite complicated ( using just the keyboard) although as you get into the game you get more and more used to it, eventually mastering it ( hopefully). And yes you do have to close it using task manager... but who cares!
Now the good stuff!!!
As with all zombie games its quite exciting to play and there are some excellent scenarios. However towards the end you end up fighting more humanised zombies rather than your average zombie, which kind of sucks.
The choice of weapons is quite good with a limited choice in upgrades but allows you to customize leon to what weapon you prefer. If you like zombie killing this is your game!!!
if not get Crysis:P
