Its an older mod that is very fun and there is no download for it so im gonna post it here. (i have 2 versions one that is extended) This mod adds 100s of new units. this mod might be old but its good and all you do is put it in the mods folder and if that dosent work try coping it to the main folder! PS: all the credit in this mod goes to Demon Squirrel not me!! and this mod will not be updated i will have it uploaded soon and ill try to get so pics. for you in the mean time.
