About Galaxy Space Defender

Galaxy Space Defender loads a full Two-Player Arena game into one page: no install, no account, no waiting.

The core mechanic is shooting.

Main controls: shoot.

You also get boss fights.

It starts within seconds even on 3G, and keeps your progress in the browser so you can stop halfway and come back later.

Every control is on screen, so there are no long instructions to memorise.

If you are collecting Two-Player Arena games for downtime, this is a good one to bookmark.
