The comment below should be used on webpages as a description
of the Alien versus Predator Mod Pack:

'The AVP Mod Pack takes Civ II to the stars, where Colonial Marines, Aliens,
and Predators battle for supremacy. Version 2.1 fixes bugs and makes
several minor improvements to earlier versions. 
Also included is a new scenario, based on the movie Aliens, 
which is optimised for use with the Scenarios CD.'
