How to survive high-speed waves and defeat the Alien Mothership.
🎯 1. Target Lock Mechanism
Press the first letter of any falling ship to lock your laser turret onto it. Once locked, complete the remaining letters to destroy the target before it hits your base.
⚡ 2. Golden Power-Up Ships
Golden vessels carry special words like NUKE (EMP wipe), FREEZE (5s time freeze), and SHIELD (repairs 30% base health). Prioritize them!
👾 3. Wave 5 Mothership
Every 5th wave brings an Alien Mothership with massive armor. Type multi-phase defense sentences rapidly before its plasma cannon fires!
