#20. Far Cry Primal
Set in an age where giant mammoths roam the earth and the sabertooth tiger is the apex predator, Far Cry Primal takes the Ubisoft FPS franchise into prehistoric times. Without any guns to play with, gamers will have to make do with stone-tipped spears and crude hunting bows to down hostiles, both human and animal. Players will also be able to befriend and tame a variety of wild beasts and fight alongside them.
