The art is bright and fun, but the narrator really makes this game fantastic - narrating every move as you shoot and smash your way through the story.

Hotline Miami [Steam store page]
Prepare to enjoy smashing open heads with a bat, slitting throats, and shooting enemies at breakneck speed in a psychedelic environment.

Beat Hazard [Steam store page]
An interesting mix of music and gaming - enemies generated by songs. Disappointing that they charge extra for multiplayer (DLC - BH Ultra).
