Indeed. I've installed kush-extreme version 0.26.2 via the in-game interface. Thanks for developing this, and thanks to the WFG team for getting it signed.
freyyja, TwainRick and I were able to easily beat 5 "Very Hard, Aggressive" vanilla bots that were using the Gauls civ in alpha 26 rc3, so the bots needed an increase in difficulty.
A bot with "Hard" difficulty using kush-extreme is much more difficult. I was able to survive, but it took 24 minutes for me to obtain a battering ram. Maybe I'm not exploiting the bot's low intelligence enough by building diversionary structures, because the bot was wiping out most of my army with each attack. This is good, because it increases the skill ceiling of the bots.
It kind of reminds me of Jebel Barkal, where the opposition Kushites civ ("Napata") has quite strong units at mid game, depending on difficulty setting. Is that part of the inspiration for the kushites-extreme mod?
