Killer is Dead on PC is now available for pre-purchase at 10% off until the release date of May 23, 2014. Preload should be available from May 16th onwards! The Nightmare Edition includes the "Smooth Operator" DLC -- previously released for the console version -- as well as a brand new Nightmare Mode difficulty in which you can only kill enemies with skillful play (so no button mashing). Japanese and English audio is included, with your choice of subtitles in English, Japanese, French, Italian, German, and Spanish. Please note that Windows XP is not supported for this PC version. Steam Trading Cards will also be available for Killer is Dead - Nightmare Edition.
