Ghostbusters: Sanctum of Slime

The "Subway Smasher" is the boss which appears at the end of Subway Smasher (level 5). To defeat this enemy, simply shoot any of your weapons at him. He has 3 moves: slam, fire breath and fire balls with bugs. To avoid the slam and fire breath stay to either side of his head and near the edge of the area (he shoots and slams in a triangle shape from this head outwards) and to avoid the fire balls and bugs you must dodge and shoot.
