So I've found two somehow possible ways to do it, on Scorpion mission as NRF
Sprint to the ladder
and jump on it when very close
Now here's the problem. I can't reproduce this each and every time. Sometimes I just can't do it during entire match, sometimes I can ghost for half of the round knifing everyone around.
Sprint to the ladder start climbing
and when near the top jump to the side
and then again jump up
Any tips how to use this bug (before it will be patched on 22nd)? Maybe I'm doing something wrong
