Hentai Killer casts the player as an anime girl fighting to stay alive against anime zombies. Its central objective is direct: shoot the approaching enemies, clear the area, and keep them from getting close.
The combat is framed around four different weapons and zombies with different abilities, while the game also describes its AI as advanced. It lists one map, giving the action a concentrated arena-like setting, and offers a mode without the HUD, toggled with the Q key. These details suggest a design built around readable combat and repeated attempts to manage threats in a bounded space, without requiring a broader campaign structure.
Multiplayer is among the listed features, and the store categories identify single-player, online PvP, and online co-op, alongside a leaderboard. Those formats give player-count figures a useful context: Hentai Killer is presented as both a solo survival shooter and a game with competitive and cooperative online options. Steam achievements and trading cards are also listed, rounding out its platform features.
