This game is gory! Having only just started with the game I am yet to really get into it but so far its been good. You get your hands on some good weaponary early on and the story begins to unfold. The feel of the game is very similar to the Bioshock games where not much of the game environemt is very interactive and all the models are static but the environment is well designed. Basically the environments are quite scripted and not much in the way of physics like half-life etc. The story unfolds as you find tape recordings, written notes and movie reels, again very similar to Bioshock. I particularly like the way time shifts as you progress in the game and the world around you changes from present time to the past. Theres some genuine jumpy moments in there too.
The game runs on the unreal engine and runs at a fantastic framerate on my mid range gaming machine at max settings and resolution, this is most likely because the game is also a console port to the PS3 and XB360 so changing detail settings is very limited. Its pretty much a generic low, medium or high setting and a choice of resolutions which may be a blessing to some people to avoid tweaking all the various settings to find that steady framerate. Id recommend downloading the latest official patch for the game that corrects some graphics problems some people are experiencing whereby the texture quality will drop in and out. Its something to do with how the unreal engine pools textures.
The main feature to the game is the ability to slow time for that slow-mo sniper shot or manipulate time by placing explosive barrels near to enemies so when time unfreezes they can be blatted into a big mess. Lots a fun.
The atmosphere is creepy, the time shifting is a good feature and the graphics look great. Recommeded.
