Alien Breed 3D II: The Killing Grounds is the fifth game in Team17's Alien Breed franchise, a series of science fiction-themed shooters largely inspired by the Alien films. It was published in 1996 by Ocean Software. Team17 had originally intended this to be its final Amiga title. Following the success of Worms, Team17's first multi-format release, the company was looking to get out of the Amiga game market, which had become stagnant over the years. As it transpired, The Killing Grounds was not Team17's final Amiga title—Worms: The Director's Cut was released the following year.
