Very satisfying game.
Other weapons includes guns and shotguns, but they don't even compare to the glaive, really.
Well, the story, as I said is awful. It has not depth, but the gameplay, as other reviewer has said, is tight. Some parts are very toughs, and the bosses are great. They can't be killed in a normal way. You have to think how to kill them because all of them have special weaknesses.
The length is reasonable. You can finish the game in about 8 to 10 hours. I haven't try the multiplayer though, because I'm not very interested.
The graphics are awesome. Very detailed. But some parts are very "dark" as the title say. Even with your flashlight you can't see very well and that's the only complaint that I have with the game. But anyway, instead of that and the horrible story, it's a very recommended game because of it's great gameplay and awesome graphics. Try it at least.
