About this game

Alien Assault II places a marine inside a starbase overrun by hostile creatures. The packaged instructions describe a mission to reach the central reactor, destroy it and escape. Movement between areas involves teleporters, and locked routes require the appropriate cards or computer access.

Arrow keys move, Alt fires and Ctrl makes the marine run. To activate a computer, approach it and press Alt; shooting and interaction share the same key. F1 opens the options, including game speed.

Look for health, ammunition and access cards while working through each area. Floor arrows can restrict travel to one direction, so a route that lets you enter may not let you return the same way. Check the surroundings before using up ammunition or committing to a narrow passage.
