New beta build! https://wiki.arcengames.com/index.php?title=AI_War_2:Multiplayer_Alpha_And_Beta#Beta_2.717_Tuning_And_Optional_Capture
You need to use the current_beta branch on Steam to play this one. This one makes a number of refinements to the last version, which had things like broken GCAs, etc. One reason among several that we went to the beta branch over the weekend.
The game is indeed far too easy right now, but the frigates are no longer so ridiculously overpowered as they were in the prior beta build. We need to do a few things to make the AI a bit more beefed-out to match all the large power improvements that players got in the last build, but we'll take this a few steps at a time.
We also fixed a number of bugs, a number of mods were updated by their authors, and capturing things like golems and arks can now be paused or even halted entire -- that's a pretty handy new power! You also no longer have to worry about Poltergeists in most games unless you get into a mega faction like the Fallen Spire.
Next build, expect further refinements and bugfixes, but also some notable buffs to the AI forces to give them a fighting chance against yours -- particularly in the early game. It's not super clear to me yet whether the new balance is still too strong in your favor in the late game, but in the early game it's no contest in favor of players. This is why we do a beta for a bit!
