Killer Is Dead: Nightmare Edition won't lend PC gamers its dose of quirky Grasshopper Manufacture action until May 23, but fans can check its system requirements right now and plan accordingly.

With minimum requirements calling for Windows Vista 64-bit, a 2.0GHz processor, 2 GB of RAM, a GPU that can handle Shader Model 3.0 and 13 GB of space, Nightmare Edition shouldn't be too taxing for your gaming rig. Recommended specs jump up a bit, calling for an Intel Core i5-2400 Processor, 8 GB of RAM and a NVIDIA GeForce GTS 450.

The $20 Nightmare Edition adds a difficulty mode, includes the Smooth Operator DLC and offers a theater to re-view cutscenes. Aside from its uncomfortable Gigolo side missions, we'd recommend giving Killer Is Dead's bizarre brand of combo-driven action a shot.
