Star Citizen is an upcoming space trading and combat simulator video game for Microsoft Windows and Linux.[6][7] Star Citizen will consist of two main components: first-person space combat, first-person shooter elements and trading in a massively multiplayer persistent universe and customizable private servers, and a branching single-player and drop-in co-operative multiplayer[8] campaign (titled Squadron 42). The game is built on a modified CryEngine and will feature Oculus Rift support.

Both Star Citizen and Squadron 42 are set in a 30th-century Milky Way centered around the fictional UEE (United Empire of Earth), an analogue of the late Roman Empire. A central theme of the game is citizenship (or lack thereof) in the UEE, which must be earned through player actions (such as completing a period of military service). It is anticipated that Citizens will enjoy certain in-game benefits, for example paying a reduced tax rate or having easier access to interspecies trade,[9] but the exact details are yet to be determined.

A strong focus will be placed on player interaction, with player behaviour influencing and being influenced by a dynamic economy system.[10][11]

Star Citizen is currently being developed by Chris RobertsCloud Imperium Games, founded in 2011.[12] Roberts’ previous works include games such as Wing Commander,[13] Wing Commander: Privateer,[14] Starlancer and Freelancer
