You can choose to fight on either the Good or Evil side, and in all of the biggest
battles from the Lord of the Rings movies!

EA tells it like this -

In this exciting, action strategy game, players fight on the side of both Good and Evil in all the biggest battles from The Lord of the Rings movies. The Battlefront format allows them to switch between characters at will, to suit the circumstance or their style, reliving – and even reinventing – the chaotic and engrossing conflicts from the films as they choose how best to tackle their objectives and defeat their enemies. In online multiplayer, gamers can choose to be Evil from the outset. - EA
