This isn't a particularly bad game. But it isn't a particularly good one either. What makes it so disappointing is that the first in the Blood series was very dark and atmospheric, much like the horror movies it was parodying. This one however did not have much of a horror feel, and it did not even come close to being as good as the original. The original was humor mixed with horror, this was just humor, and not very good humor at that. Leviticus 17:11 "For the life of the flesh is in the blood: and I have given it to you upon the altar to make an atonement for your souls: for it is the blood that maketh an atonement for the soul." (KJV)
This game is worth the price for the module toolset alone! (Romans 10:13 For whosoever shall call upon the name of the Lord shall be saved.)
I don't even play the regular game. I simply go to the editor, choose a massive map, and place soldiers and whatever else I feel like. Then I play. In this sense it is like the ultimate sandbox game. The worlds are enormous and you can place anything in them that you want. Arma Gold Edition is basically the same, but with much better graphics. The game itself is not for everybody. Imagine a sort of open-world Rainbow Six or Counter-Strike, only more realistic than both. Personally I prefer very fake first-person shooters like Doom and Quake. But since you can make your own missions, you can make the game to custom suit your tastes. I like to think, "What if I put these guys behind this building, with these guys helping me, and this tank here...?" and so forth. Then I play.
