A chunky co-op merge tower defense. Drop turrets, fuse two of a kind up the rarity ladder to Legendary, and hold the grid with a friend on one shared health bar.
Play solo any time — an AI ally holds your second lane while you learn the grid. No ads, no pay-to-win.
Every turret starts Common. Merge a matching pair and it jumps a tier. Reach Legendary and it can evolve mid-battle into one of three specialist forms — each with its own trick.
Seven turret families, each fighting its own way — and a boss crashes in every fifth wave.
You defend the bottom lane, your partner defends the top — and you share a single health bar. One leak hurts you both, so every merge and every mine counts. Team up in real-time online co-op, or hold both lanes solo with an AI ally.
Get matched against another commander for a fast head-to-head. Send minibosses charging down their lane, outlast theirs, and move your Elo. Claim a username to enter the global leaderboards and chase the crown.
Crack packs for turret parts, pour them into the families you love, and push your account level. Add friends by username and pull them straight into a co-op run or a friendly duel.
