I've started designing and building a huge level in Unreal 4 to teach players how to use the Titan Gear System.
Below is the general shape I'm working towards, splitting the map into quadrants that teach different uses of the Movement System, ultimately leading to the northern section which is an open sandbox area.
Building this level has revealed some weaknesses and areas of potential polish in the movement system, so going forward I'll be balancing working on the system with building the rest of the level, allowing each to influence the design of the other.
Also, when I say huge, I mean huge. The Player is about the size of a pixel in this picture. This system lets you move REALLY fast.
