A really cool game which deserves to be on top 1.
This game includes everything a guy like me wants. It starts off with a cool introduction of your character telling he's in danger. Thanks for adding a history to an action game with a lot of blood. That makes the game include more than just shoot 'em up.
The one thing I find weird is the slim chances of actually finding a weapon when spending 9-10 hours searching. I don't know what formula you used to script that, but I found it weird that with 3 people at my team and 9 available hours to search for a weapon, I found nothing but a dead mate after the search.
Your story should pop up more than it did. If you after like every 3rd of 5th day had a continue of the story, that would add another buff to the game.
This game is really worth a try. It's "only" 20 levels, and they are not boring at all. Every scene is just the same as the other one, just that it gets more intense during game play. Worth your time!
