How to Play Aliens (World set 4)
Quick start
Try low shots against small enemies and check which weapon you picked up. On the APC, remember that the second button fires rockets from a limited stock.
Controls
Move with the joystick. A fires while standing and B fires while crouching. On the APC, A uses the basic weapon and B fires an available rocket.
Aliens (World set 4) — About this game
Your smart gun can give way to a flamethrower or rockets as the route switches between side-scrolling sections and other viewpoints. Firing height matters against smaller creatures. APC sections also change the second button’s function, so check the situation before attacking.
