Strategy

Winning isn’t about spray‑and‑pray. Start each wave by positioning your squad in the lane that faces the biggest threat. The three‑lane system forces you to juggle front‑line fire with back‑line support. Upgrade your weapon loadout early—shotguns shred clustered Zombie packs, while rifles keep distance threats at bay. Use air support (A) when a massive horde overwhelms a lane; the blast clears space and buys precious seconds. Deploy the support squad (D) to hold choke points; they act as a moving wall, buying you time to reload or switch gear. Grenades (F) are perfect for breaking enemy formations; a well‑timed explosion can turn a losing wave into a clean sweep. Keep an eye on the pause menu (P) to check your stats and adjust your strategy on the fly. The longer you survive, the more upgrades unlock—better armor, faster reload, even a drone that auto‑targets high‑value Zombies. Master the rhythm of lane‑switching, weapon swapping, and support calls, and the defense line becomes unstoppable.
