DAMN!!! The first thing that came to mind when I read the title of this game was that scene in the Teenage Mutant Ninja Turtles live action movie where Raphael got his arse kicked by Casey Jones. It's nowhere near what this game is about, but truth be told I still don't get why the game is titled DAMN???
DAMN, by closest comparison, is a top-down twin stick shooter with gameplay that is not unlike that of the base structure of Hotline Miami. You are some cybernetically enhanced punk with an interchangeable weapons arm that is on a repeated mission through several different locales. You rescue civilians, kill robots, plant a nuke, and get the hell out of Dodge before it explodes before finally facing off against the robot's champion. What stands between you and those objectives is gated access, limited health, and the previously mentioned robotic mobs.
