Scarab out of limits
This trick allows you to make the scarab go out limits. So its also a good way to go out of the map.
first kill all the enemis near the scarab and on it. Then kill all your allies.
climb on the scarab and hang yourself to a turret. Then wait a bit. The scarab will start to move out of the map, if he doesn't start moving then get off the sarab and climb on again. Do this manipulation until he starts moving.
WARNING: if you are out of the limits and that you let go of the turret then the scarab will go back to hisinitial place.
