Trevor McFur in the Crescent Galaxy is a 1993 horizontally scrolling shooter video game developed and published by Atari Corporation for the Atari Jaguar. The game stars Trevor McFur, a corporal in the Interplanetary Defense Squad's Circle Reserves chapter. The Crescent Galaxy has been conquered by an entity known as Odd-It, whose purpose is to make every living being like it. Alongside his partner Cutter piloting a shuttlecraft, McFur must free four moons of the planet Cosmolite and defeat Odd-It.
Crescent Galaxy was produced by James "Purple" Hampton, who designed it with programmer Eric Ginner and art director Susan G. McBride. The project entered development at the same time as Cybermorph. Ginner had ideas for a side-scrolling shooter while Atari wanted a mascot similar to Mario or Sonic the Hedgehog, which resulted in Trevor McFur's creation. The game was given a short deadline to meet the Jaguar's launch before other consoles were released, leading to several cut features. It was considered as the Jaguar's pack-in game until Atari chose Cybermorph instead. The game was released in North America in November 1993 and in Europe in June 1994. Mumin Corporation published it in Japan in January 1995.
