Invasion
Contains a script but its compatible with most mods out there
Best used with Diplomacy and AI, but also mods like Faction, Empire and Movement + Supply System would really make a difference.
Submod and stand alone version of "Very Hard Campaign Overhaul" and "Radious – Very Hard Campaign Overhaul" (you don’t need this if you are subscribed to those overhauls and Its made for Vanila version and mods that did not altered same script.)
Changes:
– Attila becomes mortal after defeating him once instead of twice
– Spawning distances has been changed slightly
– 4 turns before system will test if there should be a new spawn of Hunnic armies instead of 2
– Maximum number of spawned units has been doubled and is now 6 (so its less gradual and it will give AI and player some breathing space but it allows Huns to come in bigger hordes
– Quality of units has been improved
– Maximum number of spawning hunnic stacks

I have been inspired by no longer updated version of "Weaker Hun Invasion" by Magnar.
