The Single-Player Map Update #1, released December 12th, 2001, makes several changes to the Aliens vs. Predator 2 single-player missions.NOTE: Because this update makes changes to some of the single-player levels, saved games made before the update was installed may not work correctly once you install the update. Your level progression on each species' mission selection screen will carry over correctly, however, so we recommend that you finish the current mission before installing the update and then resume your progress from the mission selection screen after the update is installed.
