KILL KNIGHT is an action game from developer PlaySide. Players control a reanimated knight, branded KILL KNIGHT, tasked with slaying the last angel. The core gameplay loop involves fast, visceral top-down combat that rewards aggressive, precise play. Players descend through five increasingly dangerous layers of the Abyss, exploiting enemy weaknesses, using brutal executions, and managing resources.

New equipment and playstyles are unlocked through challenges, allowing for player evolution. KILL KNIGHT features retro visuals reminiscent of 90s arcade shooters and includes global leaderboards for high-score competition. The game offers four difficulty settings and a Sever Mode that combines all five layers into a single arena challenge.
