Mutant Rush

About Mutant Rush: Evolution Battle Arena for 12 Players

Mutant Rush is an evolution battle arena where up to 12 players compete to become the last monster standing. Every match begins the same way — you spawn as a tiny larva — but diverges immediately as you eat biomass, level up, and shape your creature through a sequence of mutation choices. With 16 mutations, 6 synergies, and 13 species to collect in the bestiary, no two runs play out identically.

Mutations are not just stat bumps; each one visibly reshapes your creature's body and changes how it fights. Spikes, claws, jaws, an acid gland, a shell, wings, pincers, and webs are among the options, and stacking the right combination unlocks named synergies like the Armored Hedgehog or the Lightning Predator. Beyond other players, the arena holds the giant Leviathan to take down and a bounty on whoever holds the lead — all while a toxic mist closes in from the edges. Online matches fill empty slots with bots, and a solo mode is also available.

Five biomes, random conditions, and live events mean the map refreshes every match. Signed-in players access ranked mode and seasons, and recurring modes include a daily challenge, weekly King of the Nest, Single Mutation, and Raid. Quests, achievements, mutation mastery, and skins round out the progression, and a replay system lets you watch matches back and save video clips. Mutant Rush runs on desktop and mobile, with support for English, French, Russian, and Chinese.

How to Play Mutant Rush

Start each match as a larva and eat biomass to grow. Each time your creature levels up, three mutation cards appear and you pick one, gradually building a body and a fighting style from scratch. Combining the right mutations can trigger powerful synergies, so the choices compound as the match progresses.

Rivals can be crushed against rocks, and hunting the current leader earns a bounty. Taking down the Leviathan is another objective on the arena floor. The toxic mist continuously shrinks the playable space, forcing confrontations. The last monster alive wins.
