I know that Carmageddon is owned by 2k Games, and Redneck Rampage is owned by VU Games (correct me on that if I'm wrong), but what about the other titles?

I still own the Action Hall of Fame, too...but I lost the damn Redneck Rampage disc. D:

Interstate is owned by Activision I think.. but I may be wrong since Activision sold a lot of its IP recently.

I have been playing Descent to undermountain and actually enjoying it until I became stuck in the "prison". Are you aware of any guides to the game and specifically this section?
