Perhaps. I think a spiritual successor would work just as well, given the amount of backstory revealed in the game. [spoiler]In the game's storyline, after the Resistence leave with the aircraft and contact people on the mainland, the threat of the Ark's location being revealed is a very real threat. A sequel based off of this could feature a refugee militia versus Ark security forces.[/spoiler]

That'll be good too. And if they actually do something like that, lets just hope they don't do a repetitive storyline again.

While I liked how they tried to tell a story from both sides, a change of colour scheme and resdesignation of different objectives wasn't the best way to go about doing it. I think intertwining, yet distinct storylines for each faction would be much more effective.
