Such trailers won't give you anything in the way of gameplay. Heck, you can't even see the game.

But they're designed to get you all hyped up for the final product; set the tone and atmosphere, so-to-speak. Call of Juarez: Gunslinger is the latest effort from Techland (who is also working on the new Dead Island Riptide ), and it could be promising.

This is the teaser trailer for the Western-themed title, which features classic Wild West names like Butch Cassidy and Billy the Kid. And as it says at the end of the video, "Where justice fails, vengeance follows," which sort of implies a vigilante style of action. Well, of course. We're talking about the old West here, where in many cases, that was the only way to get anything done.
