Xatax is a side-scrolling shooter in which the player must defend the remains of the Alliance's guilds against the titular aliens. This is accomplished in a traditional shoot-em-up fashion, fighting waves of alien ships and stationary turrets. The player-controlled ship can become stronger by collecting power capsules dropped by defeated enemies. The game features three different worlds, of which the shareware version only contains the first.
