Rabbit & Steel frames its adventure around the Moonlit Kingdom, where a colossal tower appears each night and the city’s inhabitants attack outsiders. Players set out for the Moonlit Pinnacle, facing bosses and investigating what happened to the kingdom. Its rabbit-eared heroes bring a playful premise to a structure inspired by party-based MMO raids, without making the game itself an MMO.
Combat combines global cooldowns, deliberate skill use and gear effects with boss mechanics that call for teamwork. Runs begin with a class choice, then reward players with loot and upgrades that shape their builds; item sets can make particular combinations especially valuable. Boss encounters also bring bullet-hell patterns, giving the fights a distinct action challenge alongside their coordination demands. A single-player story campaign adds conversations with enemies as another way to uncover the mystery.
The format supports solo play as well as groups of up to four, with local, online or mixed local-and-online co-op. Going alone changes mechanics that would usually require cooperation into intense bullet-hell attacks, so the solo option has its own stated combat adjustment rather than simply describing a smaller party.
