Combat is a combination of traditional FPS shooting (and when holding pistols in both hands, forcing your brain to remember to fire the right hand weapon), until you've killed enough baddies to trigger Concentration. And then it all slots into place and begins to make sense.
At first the game feels like trying to drag a fifteen foot oar through a lake of soup, the controls seemingly berserk. This is one of those cases where a demo does a wealth of explaining about the game. Declaring itself to be a truncated version of a full level, it gives a taste of the game's core mechanics: the Concentration mode bullet time, the cover system, and a duel to test your quickdraw hand. Call Of Juarez: Bound In Blood was released just over a month ago, but finally a demo has appeared.
