I think the best word I can find for describing this game is "detached". There's a lack of response from the game. Is the gun even firing? Is that something hitting me? In fact, the most response I get is something shouting "Come get some" or words to that effect every time I fire a weapon.
The voice acting is terrible. Even hardcore fans of OFP wouldn't be able to listen to it. Graphics are pretty, but seem so 'now': We've been spoilt by the recent glimpses into the future.
The team behind this game has a lot of potential. I like the sound of what the game is trying to achieve. But the demo, at least, is another game that falls far short.
