Mix a Halo game with a basic rts and you get Halo wars it's one hell of a game! 10/10 helicopters.

Ok firstly it's not worth £14.99 but it's worth atleast £7 also this isn't really a xcom game it's more of a indepedent title, But if it's on sale cheap i would definetly recommed it. 7/10 helicopters
