(there is a gun and body armor in the ship)Just run from the freakshows until you are exeptionally far away from them, then aim with R1 and shoot them with the gun. Do this until Vincenzo comes in. After the cutscene, aim and fire at him and use the boxes to hide behind after u kill him the mission will be complete and you will have unlocked the overalls costume. Oh and by the way, repeatedly tap X to run away from the freaks.
