One Punch Man: Justice Execution is a gacha mobile game where players assemble a team of elite heroes to engage in strategic, turn-based battles. Featuring 3D graphics and voiced story cutscenes in Chinese, players can summon new characters through a gacha system, starting with a free pull that guarantees an SR-level hero. With a maximum of six heroes per squad, two spaces are initially locked. The game includes PvE and PvP modes, offering a narrative campaign and competitive arenas, though access requires authentication via WeChat or QQ.
