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 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 get taxing with some GPUs.
