Hey Supercheese, i can't thank you enough for this mod!
It's execution is totally stunning, pure joy.
In earlier "playthroughs" (better; maps) i thought about this mod it is absolutely op.
But as soon as i got natural evolution (and the likes), biters&spiters and especially worms were buffed so enourmous, i could not take on a larger bases.
And you can tweak it the way you want. Personally, i multiply the building cost by x10 and timer to 30 min.
Kudos to you, this is handdown a brilliant mod.
That you got multiple C&C voices to choose from is simply the icing on the cake!
