Idol Showdown is a free, fan-made fighting game built around hololive performers and their fan community. Its roster features recognizable hololive talents, while stages recreate locations from the virtual world and music remixes draw on hololive original songs. The result frames its combat as both a fighting game and a celebration of the performers’ shared universe.
The action is fast 2D combat, with each talent shaped around a fighting-game archetype and given a distinctive twist. Flashy attacks and moves inspired by memorable moments and personality traits make character identity central to the design. Easy-to-learn controls are intended to welcome players who enjoy hololive but have little experience with traditional fighters; rollback netcode supports the game’s online play.
Its listed formats include single-player, online PvP, and shared or split-screen PvP, so players can approach the battles alone or face another player locally or online.
