Frequently Asked Questions

How do I control my cannon?

Left/Right arrow keys or A/D to move. Press Space to shoot.

Do the aliens speed up?

Yes — the fewer aliens remaining, the faster they move. The last alien is extremely fast.

What are the shields for?

The barriers in front of you absorb incoming alien fire — but they degrade with each hit.

Are there different alien types?

Yes — top-row aliens score more points than bottom-row ones. The UFO that flies across the top earns bonus points.
