I only have a vague idea of what the Gorillini Invasion would actually include. I just know it would be a good name for a campaign about a large number of armies with high scrap:platoon ratios fighting on a big map. It’s the bigger, better super-campaign idea. Armies are more able to use very expensive toys like power armor and tanks, and the total scale of the conflict is larger. It’d probably have some kind of good vs. evil narrative, where one gorilla tribe has gone tyrannical and has invaded their neighbor. The goal would probably be to occupy the enemy capital.
The only thing I know about the Ateles Vendetta is that the name sounds bitchin’.
