Hotline Miami looks a bit like the top-down Grand Theft Auto games and their open-world descendant Vice City hooked up and had a deeply disturbed, inbred baby nine months later. Here's the official description from publisher Devolver Digital:
Step into the neon-soaked underground of 1980s Miami as bizarre messages on your answering machine seem to be urging you to commit terrible acts of violence – but will you obey? Hotline Miami overflows with raw brutality and skull crushing close combat as you find yourself outgunned and using your wits to choreograph your way through impossible situations. An unmistakable visual style, a driving soundtrack, and a surreal plot that will have you question your own thirst for blood. Bash and blast through over 20 multiscreen levels with 35 unique weapons and collect 25 game-altering masks in one of the darkest and most unusual independent games on the scene.
Hotline Miami is due out soon for PC and Mac with planned console versions to follow.
