Follow more instructions inside the game.
Use the alien forms strategically based on enemy types—some aliens are better at crowd control, while others excel at boss damage. Keep moving with WASD or arrow keys to dodge incoming attacks, especially during wave surges. Position your attacks carefully using the mouse to aim in the direction you want to strike, maximizing damage while minimizing exposure.
