THE FULL GAME UNLOCKS โ€ข All 25 waves + endless mode โ€ข A second battlefield โ€” The Quarry, where terrain fights back. Golems terraform the ground as they march, ore pockets pay out gold when cracked, and a keystone wall splits the map โ€” hold it or watch the shortcut open โ€ข Tower-smashing GOLEMS โ€” armored bruisers that stop to wreck your towers โ€ข WARDENS that raise energy shields โ€” burst them before they recharge โ€ข A deployable DWARF hero โ€” a roaming gunner only the wasps can touch, who levels up to repair wrecked towers and mine ore for gold โ€ข Bosses and the final victory stand โ€ข The global online leaderboard โ€” submit your score and claim your rank SIX TOWERS, EVERY ONE USEFUL Gunner, Cannon, Frost, Venom, Tesla, Sniper โ€” each with upgrades and a role. Freeze a swarm, chain-zap a cluster, poison the tanks, or snipe through armor. There's no single right build.
