Player with a WORKING grenade launcher in a TDM room in Comat Reloaded

Most of us have probably seen players with grenade launchers before in DM and TDM rooms before, but usually the players is a bot and can't do any damage. So is this a serious bug, or a hack?

I think red username appears when someone is misplaced inside another room, or maybe it's cuz of hack. This guy is pure hacker😑👾
