Mission 1 S.S.D.D.
After completing the tutorial, you are suppose to head into the pit. Instead, head to your right to find a sniper with three bullets. There are three clowns located outside the map that you need to kill: near the sniper spawn, on a warehouse roof across from the sniper tower, and finally on a construction vehicle near the bunker outside of the pit.
