After some testing and then inspecting some engine code I just found out that you can't change usercmd with set_uc because a copy of it is passed to CmdStart. Look like you can't do much without Orpheu or Okapi.

Also to make them move in certain direction you are supposed to change UC_ForwardMove, UC_SideMove and UC_UpMove, not just set IN_FORWARD.
