New beta build! https://wiki.arcengames.com/index.php?title=AI_War_2:Multiplayer_Alpha_And_Beta#Beta_2.724_Mod_Bonanza
You need to use the current_beta branch on Steam or GOG to play this one. If you have trouble with it, there is a most_recent_stable_beta, now, too.
This one fixes a bug in the prior version that was preventing AI Reserves from sending ships against you, and also changes up how the AI sends waves against other factions (basically they go straight Hunter now).
This new version also includes a ton of updates to our settings menu to make things more easy to find, and organize all sorts of categories of options so that you can actually focus in on specific items that otherwise were just kind of lost in an overwhelming soup of words. Like that sentence!
We also introduced explicit mod prerequisites, so that mods can define both what expansions and what other mods they require. When you enable such a mod, it now does its best to enable any other mods it depends on without you having to worry about it. Since we have a "modder framework" mod in place by NR SirLimbo, this makes it easier for other modders to use that without it confusing players.
The mods themselves now are visually broken out into their own tab, and into their own categories (normal, cosmetic, and framework). This new build includes three new cosmetic mods by ArnaudB, all of which are actually balance adjustments (but which don't break savegames to be turned on or off).
There's also another new mod, this one by CRZgatecrusher, called The Reprocessers. This is a new faction by the same name that organizes attacks, then does research, builds, has a lifecycle, and replicates.
