During the campaign of Rage you eventually are given the opportunity to leave Wellspring and the Wasteland to a different location (hopefully this isn't a spoiler). The character you are talking to mentions to finish anything up before leaving. Do they mean I will have absolutely no chance to come back to Wellspring at a later point?
I'd like to continue on with the story, but at the same time there are some achievements that I'd like to finish up. As far as I know the only ability to complete those achievements is based on specific characters that reside only in Wellpsring or the surrounding area.
