About Sid Meier's Alpha Centauri™ Planetary Pack
Lead one of seven ambitious factions in this sci-fi colonization strategy game where you design custom units and outmaneuver rival leaders with distinct personalities and agendas. With deep tactical gameplay rooted in the Civilization legacy, each faction's unique strengths and hidden weaknesses create a dynamic chess match for planetary dominance.
Key features:
- Great spin-off of the legendary Civilization series, in a refreshing sci-fi setting
- Design your own units. Balance their speed, power, and toughness to suit your current tactical needs
- Seven factions to chose from, each with its own artificial intelligence model that creates a very suggestive feeling that you’re up against real people

Literally the best turn-based strategy game ever made. I can't stand any other compared to this one. Start playing it at 8:30pm and you won't even think to check your watch until it's 5:30am. Trying to improve on SMAC is like trying to improve chess. It can't be done.1 found this helpful
This was my favorite game when it came out. It finally showed up on Steam. I prefer to play the Alien Crossfire version. BUT... on Windows 11, IT WILL CRASH as soon as the first autosave happens! This is a program bug in the game itself, not Steam's fault. There is a patch that fixes it: Adamite.exe is a program written by Nathan Baggs. Find it on www.nexusmods.com. This patch fixes the program error in SMAX that causes it to crash in Windows 11 (not previous windows versions or Linux). Running Adamite.exe will cause Windows to freak out. No worries! Just override Windows refusal to run the program. There will also be something about hash. Ignore this and continue. Adamite will create a small window. On your computer, go to C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Alpha Centauri Find terranx.exe (NOT terran.exe) Drag terranx.exe into the window the program created and run the program. It should be very fast. Go back to C:\Program Files (x86)\Steam\steamapps\common\Sid Meier's Alpha Centauri and rename terranx.exe (I used terranxBUGGYORIGINAL.exe) Find terranx_nb.exe, and rename it terranx.exe. Done. Game will run without crashing.
Alien crossfire constantly crashes
Game is super. Wish it was more supported. Problems with crashing and incompatibility issues raise a concern. Help with crashing would be much appreciated you can reach me at [email protected] and advise me with what could prevent the game from not launching from steam. Thanks!
Always an amazing game. have played it for over twenty years, great stories for all factions and world building lore. nice fast game play make it better in my opinion than the typical Civ games with slower animations.
Awesome old-school game.
