3. Shank 2
I bet most of you never heard about this game so let me clear it up for you. Shank 2 is an incredible indie game. Like the first game in the series, Shank 2 is a side scrolling beat 'em up with a comic book art style. Its story isn't that great but the bloody amount of fun you can have playing this little game is just worth your money. Also, it has a co-op mode, which makes the whole experience even better, especially when side-by-side with a friend. Just try not to hate me for picking this game above the others.
