Multiplayer only titles are known to not have much in terms of a story and Natural Selection 2 is no different. In Natural Selection 2 you either fight on the side of the human space marines known as the Frontiersmen or alien species known as the Kharaa. As they both battle for resources and dominance on the battlefield."
