Vortex Coop
An experimental mod that removes racial limits in Vortex coop – so you can play as say, Settra while your buddy plays Noctilus. Victory conditions seem to stay the same for each faction so this is more for sandboxing and world domination than for competitive Vortex play, which Head to Head mode already does perfectly well.
Should be compatible with ALMOST everything, including overhauls new unit mods etc. However, this does data core the campaign_mp_coop_groups_to_factions table so it will crash if you try to run it with another mod that does the same thing – idk if there are actually any mods that do the same thing tho, I didn’t find any when I looked.
For unknown reasons, selecting Tomb Kings in lobby is a bit buggy with this mod, haven’t been able to fix.
