Alien Breed 3D is the fourth game in Team17's Alien Breed franchise, a series of science-fiction-themed shooters largely inspired by the Alien films. It was published in 1995 by Ocean Software, and it is the first first-person shooter in the series. It is the first game that Team17 did not self-publish.
^Alien Breed 3D by john girvin "In March 1997, Team17 released the source code to AB3D’s sequel, “Alien Breed 3D II: The Killing Grounds” (known as TKG), on the cover CD of Amiga Format issue 95. It was megabytes of undocumented, disorganised, messy assembly language. Andy Clitheroe, the lone programmer of both games, must have been some kind of genius, I think. The official release was of the TKG source code. However, when poking around the CD I found the original (and equally messy) AB3D source too." (2009)
