And then this...Jack Carver isn't here. The monstrous Trigens are gone and that tropical island from the original game is over a thousand miles away.

"The game takes place in two fully open worlds that are five kilometres on a side, with the second world 'unlocking' roughly one-third of the way through the game," he explains.
"This gives a playable area of 50 square kilometres, through which the player is allowed to freely travel at any time. The story's also non-linear, dynamic and procedurally assembled using a simple drama-management engine to populate the story with key characters and facilitate the convergence of the story toward major climactic events."
