Planetwar Total War is a fantasy based mod for Medieval II Total War. It places the human race on an alien planet with many other alien and mythological civilizations.
Somewhat a really interesting mod. Actually it´s an humor mod. You will have Humans fighting aganist Predators, Shreks, Dinossaurs and many other kind of alien/creature. All this with medieval weapons.
btw, there are some bugs around. Be that missing texts, missing faction icons, and maybe some balance issues, but considering that it´s the very first release, it´s ok.
