This game is seriously one of the best first person shooters I have ever played.
What I thought I was getting was Doom with wild-west skins. What I got was the greatest Wild West adventure I've ever played, though I have heard Red Dead Redemption can top it. Outlaws has fully voiced animated cut scenes that looks like a cartoon but is still incredibly mature and badass. The protagonist is a Clint Eastwood copycat who spits one-liners while blasting enemies and solving puzzles. There's a ton of weapons, a train level, a long campaign, two discs, tons of extra content and levels, a fantastic soundtrack, great voice acting, memorable villains, and even though I've only played it LAN the multiplayer was incredibly fun. Outlaws is a classic that in my opinion trumps even Doom. It's that sick.
