Patches[edit]

Unofficial patches[edit]

If you use SMAX, you're best served by Yitzi's patch, otherwise you should use kyrub's. The AI improvements won't make the AI too hard for new players, and instead aim for a reasonable level of challenge at "Librarian" difficulty. Tweaks mostly involve teaching the AI how to do not-terribly without cheating.

This list is not updated with the latest releases of these patches. scient no longer works on the patch project, but kyrub and especially yitzi are both still active with a couple of releases a month from Yitzi in 2014 and two releases from kyrub in that year.

Latest patches can be found on the alphacentauri2.info downloads page (scroll down). Patches are developed in the Bug and patch subforum and elsewhere on ac2.

Official patches[edit]

Note: these are for the retail version of the game only. The GOG.com version already has the official patches, you should strongly consider installing an unofficial patch, though.

Now you can install the unofficial patch of your choice.

Run Without CD/DVD[edit]

The game will run without the CD but only if you have performed a full install.

Issues fixed[edit]

The game hangs[edit]

Try the Sid Meier's Alpha Centauri#Unofficial patches latest copies of Yitzi or kyrub's patches.

Otherwise, might be related to a bug with automated artillery units (though I think Yitzi might have fixed this one sometime). Try turning off automation and see if it helps. More info here.

AMD/ATI compatibility[edit]

GOG.com recommends using Catalyst 13.4 or earlier but the game also works with 14.x or earlier.
