Aliens versus Predator 2 is a 2001 first-person shooter video game developed by Monolith Productions and published by Sierra Entertainment and Fox Interactive for the PC. A Mac port was later released in 2003. The game is a sequel to 1999's Aliens versus Predator, although its plot does not connect to the previous game. Instead it follows events on the planet LV-1201, where a Weyland-Yutani Corporation research facility has become the centre of a large-scale Xenomorph outbreak. A detachment of Colonial Marines is dispatched to investigate, while the Predators also send several of their kind to conduct a Hunt on the planet.
