Strategy

Winning isn’t just about spraying bullets. Start each mission by picking a weapon that matches the enemy wave composition. The shotgun tears through close‑range swarms, while the rifle whittles down distant threats. Keep an eye on the lane indicator – a missed shift means a Zombie will flank you. Air support is a game‑changer; call it when a massive cluster blocks your path. Your support squad can hold a lane for a few seconds, buying precious time to reload or regroup. Grenades clear tight choke points and reset the flow. Upgrade your arsenal between rounds; each improvement adds a layer of survivability. Remember, the longer you survive, the tougher the next wave, so balance aggression with positioning.
