How to unlock the Galboss achievement in GALAGA - Definitive Guide
The Galboss appears on level 12. He looks like the creature in the achievement image. It's not necessary to finish the level to get the achievement, though you must finish your game before the achievement is awarded.
The Galboss can be found during level twelve. You do not need to destroy it; you only need to find it. It does not matter if you pass the level or die, the achievement will still unlock.
