Hard Reset

Developed by Flying Wild Hog, a studio that prides itself with the fact that its creation is PC exclusive (bless them), Hard Reset is a first-person shooter that's set in a future cyberpunk setting of a dystopian world. It reintroduces many of the gameplay mechanics that have made classics such as Quake wickedly fun to play and that are sorely lacking in today's tactical military shooters, thus creating a 'void' for Flying Wild Hog to fill.
The game uses the studio's in-house Road Hog Engine, which isn't particularly heavy on new-generation DirectX features, but can still be taxing for some GPUs.
