From Grasshopper Manufacture, comes 'Killer is Dead - Nightmare Edition,' the PC version of the 2013 console game. Published by Deep Silver, not only is the PC version of this heavily stylized title value priced at $19.99, but the 'Nightmare Edition' includes both the Smooth Operator DLC as well as some other bonuses.
Chiefly, beyond the Smooth Operator DLC, which adds a new mission, boss, items, etc., there is the new Nightmare Mode difficulty, which specifically ups the skill needed to defeat enemies beyond simple button-mashing. "enemies can only be defeated using the following attacks: Adrenaline Burst, Dodge Burst, Headshots, so the gameplay requires far more skill and tactics. Players will not be able to use the Final Judgement finisher (QTE mode) to defeat enemies."
The PC version also gets Theater Mode for replaying cutscenes.
