Extreme Unit Size pack for Total War: ATTILA.
Doubles the size of units.
I strongly recommend the mod “performance maker for massive battles” by WhyXelsink, i don’t think its even duable without it. Link: https://steamcommunity.com/sharedfiles/filedetails/?id=1493472759
I would also recommend a Geforce GTX 1070 or better for battles with 30000+ men.
Enjoy being a tactial mastermind
