New build! https://wiki.arcengames.com/index.php?title=AI_War_2:Finalizing_Multiplayer#2.805_Relentless_On_Several_Levels
This fixes an absolute metric ton of multiplayer bugs. It also makes the "relentless" AI waves way smarter, and able to pursue more complicated and unexpected objectives.
This version also introduces per-difficulty variants of the AI Overlord (the final boss), so that the challenge is appropriate at each level. We had based it around difficulty 8 during the paradigm shift, and donblas was quick to let us know how much of a difficulty spike that created at the end of a difficulty 6 game. The overlord should now be nicely tuned for each difficulty level, with 9 and 10 being even harder than before. Speaking of difficulty 10, there are two different versions that you can run into; the x-4000 and the PFFN. They are definitely terminators in relentless pursuit of your tasty home station.
A lot of other bugfixes and balance tweaks in this one, and still working on DLC2 art as well. One key balance change is to make the dyson sphere substantially LESS relentless in turning its neighborhood into a parking lots for its giant (now unopposed) armada. They were a wee bit overtuned.
Enjoy!
