How to Play Space Invaders '91
Quick start
Move the cannon along the bottom and destroy each descending formation before it reaches you. Use shields as temporary cover, target high-value UFOs, and collect power-ups. Preserve lives for the faster late waves.
Controls
D-pad Left/Right: Move the cannon. A/B/C: Fire. Start: Begin or pause. Fire through gaps, step out from behind shields only when safe, and prioritise the lowest invaders before their march accelerates.
