Civilization developer Firaxis is making XCOM: Enemy Unknown, a re-imagination of the classic turn-based strategy game.
US magazine Game Informer revealed Enemy Unknown, saying it "introduces a wider console audience to what made the storied franchise great in the first place". It launches on PC, PlayStation 3 and Xbox 360 this autumn.
"Unlike 2K Marin's previously announced XCOM shooter, which sparked tempers among longtime fans for turning its back on the series' cerebral roots, this title is a full-on strategy game that puts players in command of a global anti-alien defense force," Game Informer said.
"XCOM's leader needs a worldwide perspective where threats are identified, populations reassured, and national leaders mollified - but a tactical mind is just as critical considering every shot XCOM's soldiers fire on the battlefield is under the player's turn-based control."
Firaxis boss Steve Martin added: "It's been a dream of ours to recreate X-COM with our unique creative vision. We're huge fans of the original game and it's a once in a lifetime opportunity to re-envision a game that is as beloved as X-COM.
"We were careful to keep XCOM: Enemy Unknown true to the elements that made X-COM such a revered game while delivering an entirely new story and gameplay experience for both die-hard X-COM fans and newcomers to the franchise."
Firaxis' XCOM has destructible tactical environments, and fuses a real-time strategic view with turn-based combat.
