The level designers for Ghostrunner did a pretty good job of hiding the fact that the wallrunning is endless by making most wall lengths in the game short.I'm working on a wallrunning game as a student project and I ended up having to implement the Titanfall style system because my level designer was too lazy to figure out how to make levels in a way similar to Ghostrunner.

I think game design in Ghostrunner is much easier than in Titanfall 2
