Hard reset is a lot of fun and looks absolutely amazing.
It is the perfect game to play if you only have 5 minutes to kill and you want to blow stuff up. The shooting is simple and satisfying. There is a wide variety of enemies, and they so aggressive that it keeps things interesting. There are only two primary weapons but they can be upgraded many times each.
Hard Reset has some of the best graphics I've ever seen. The textures are very sharp and detailed, unlike most PC games I've played in the last few years. The environment, the enemies and the color scheme and look fantastic.
There isn't much depth, but who cares? You get to shoot a ton of robots!
