Our take on Sid Meier's Alpha Centauri™ Planetary Pack

The bounce point arrives when faction differences become central to decision-making. Players who do not want to learn separate agendas, goals, strengths, weaknesses, and artificial intelligence behaviors may find the seven-faction structure demanding before unit customization becomes useful.

What is Sid Meier's Alpha Centauri™ Planetary Pack?

This collection contains Sid Meier’s Alpha Centauri and the Alien Crossfire expansion.

It presents a science-fiction strategy campaign about humanity’s attempt to establish a colony on another planet. Players choose among seven factions, each with its own agenda, leader objective, and artificial intelligence model. The factions have different strengths and weaknesses, requiring players to adapt their approach to the group they lead and the opponents they face. The game also includes a unit-design system. Players can adjust a unit’s speed, power, and toughness to match current tactical requirements. The package combines the original game with its expansion in one planetary strategy setting.
