Passable slope is a parameter of robots given in degrees which describes the maximum terrain slope over which the robot can pass. There are three values of passable slope: 56°, 51° and 45°.
A terrain overlay showing the different slopes is available. The 'L' key is the default key to access slope capability overlay and will cycle through the 4 different settings.
Off: No slope capability is displayed
Current robot capability: Overlays impassable terrain for your currently active robot by means of a white bordered, diagonally filled box. The colour of the fill will depend on the slope capability of your current robot.
All capabilities: Overlays impassable terrain for all slope capabilities. Impassable for your current robot is outlined with a white border. Impassable for 56° capability robots have a white overlay, 51° capability robots have a dark blue overlay and 45° capability robots have a light blue overlay.
Structures: Overlays areas unsuitable for deploying MPC structures as well as impassable terrain for all slope capabilities. Areas unsuitable for MPC structures are overlayed in yellow.
