When a model is climbing and falls unconscious, does it fall from its climbing position, or hang there? (supplementary question, if it hangs there, does it go prone?)
It stays. The only way to fall is ti jump. As to the later. No idea. Id suggest no due to the climb rules
Can't go Prone, as specified by Climbing rules. If it gest Unconscious, the model would hang there (and you better have a climbing plus engineer or a Medikit-carrying dude nearby, else the model will remain there). I assume the "explanation" is that they have a rope, and when KO remain there, propped against the wall in the least favourable position.
