OpT1mUs: So Hive is apparently immune to inefficiency, it cannot go below 0. Only place I found about is is the game wiki, it's not mentioned in the manual nor in the game (as far as I know) ? Why is this? Are there other hidden faction bonuses like that one?
The Hive's immunity to inefficiency isn't in the manual because that trait was added in a patch. See the section of the readme.txt file titled "CHANGES IN ALPHA CENTAURI VERSION 2.0." The Believer's +2 SUPPORT isn't in the manual, but this appears to be a simple oversight. The Usurper's -1 PLANET isn't in the manual, but was added in a patch (again, see the section in the readme file titled "CHANGES IN ALIEN CROSSFIRE VERSION 1.0.").
