As long as people keep playing this game with low-end devices, FM won't include Green Hell because it takes too much system resources. Sucks for those who have the resources, but can't because of reasons I just mentioned. There also might be engine limitations, RR3 is ancient in that regard.

Wouldn't mind Green Hell as an optional DLC which would only be visible on supported devices.

To sum up, don't get your hopes up. You're better off with removing that thought from your head.
