A moving/dynamic zone would be cool (e.g. a ship or train)

I feel like that the doom train fight is good and bad because it kinda embodies this a touch. They couldve gone farther with it (where the doom train slowly destroys the train your on, and if youre not fast enough, you run out of train.) Among other mechanics like needing to switch tracks or even trains possibly (havent done the Savage version, so if that is a thing on savage, woo. Gotta go do that then :3).

phantom train is not doomtrain.
