Get Mr.Addon in Sulpicius Gallus M for PC

Mr.Addon in Sulpicius Gallus M is a 2D platform game about a cosmic renegade helping awaken the “Big Human,” who lies asleep in part of the Sulpicius Gallus M crater. You battle system maintenance technicians, Dominion aliens and replicating cyborgs across three worlds, each ending with a boss.

Combat and puzzles

Mr. Addon fires multi-frequency “rainbow” rays that turn enemies into moons, snowballs or fireballs. You can then roll these transformed enemies into others to defeat them. The levels also use ice, fire and teleportation portals, and include sharp puzzles that require you to work out how to navigate each screen and eliminate its enemies.

Modes and progression

You can play in Arcade mode or Level Selection mode. The game cannot be saved, and continues are limited. Difficulty rises as you progress, mainly through more dangerous enemies and increasingly challenging screen layouts.

Three worlds

The game has three levels to complete in a row, across three worlds, with a final boss at the end of each. Its pictorial work is by Peláez Ochoa, and its music is by unTIL BEN.
