Activision and its developers have been inching towards science fiction with the Call of Duty franchise for years now, but with Infinite Warfare they've finally taken the plunge. In the campaign mode you play as Captain Reyes, a Tier 1 Special Operations pilot at the helm of the Retribution, one of Earth's last remaining warships, in a conflict not just for our planet, but for the whole solar system. See, in Infinite Warfare's future the Earth's resources are spent and our world relies on colonies spread across the solar system to provide it with resources. Not all the colonies are happy with this set,up, though, and the fascist SetDef, hardened by years in extreme environments, seeks to control these outposts and put a stranglehold on the countries of Earth. It's into this conflict that you step. As is befitting this interplanetary set,up, the action takes place across a wide array of environments that bring their own twists on gameplay. In particular, Infinity Ward has included zero,g combat, in which players can move around using a grappling hook and attempt to outflank their enemies.
