One word describes it "UNPLAYABLE"
That's the good thing about it... Let's talk about the bad things, at first i didn't want to believe the official review from GS, but once i played this game i found how unplayable is it, If this game is not a candidate for the worst game of this year then I don't know wich one could be.
Th game sucks for one main reason, It's UNPLAYABLE, soon after you install it you'll face a lot of problems, lots of people got an error message related to PhysX, once you solve this by erasing a file in the folder where the game is installed if you manage to run the game you'll deal with its ETERNAL LOAAAAAAADING Times.
After the 2 to 3 mins that the games takes to load you'll start a game that runs less than 10 FPS, I'm not kidding you!
If you manage to play it you'll find lots of bugs, glitches and other stuff that will make you hit your PC.
Don't even bother to look for help or support from the developers, in the offical forum of the game there's a moderator who will try to help you, all other users are fan boys (AKA: Game staff acting like forum users) Who only post messages praising the game and talking about how wonderful is it, if someone comes with a problem or critizices the game they'll make sure you look like an idiot, and like it's your fault or that your PC can't handle the game.
I can run much better looking and heavier games than this and they're very playable in my mid spec PC, so this guys are obviously game's staff or paid fan boys, they start threads in the forum with titles like "MADLY IN LOVE WITH SHADOW HARVEST" Go to the official community of the game and you'll find it.
The game looks very monochromatic, everything is yellow, it doesn't look that bad at all, but it's dated and runs bad.
Ok, if the game was barely playable, then it would be a half decent shooter, no more than that, it's ashame because it seemed like a good idea and the setting is quite good, it has high difficulty wich is good, beacause most games today are very short and easy. but it's an unplayable mess that should have stayed for at least 6 month more of development.
