Deathslinger and Clown are not living up to their character fantasies
Some work needs to be done to the deathslinger and the clown to make them live up to their character fantasies.
Deathslinger, the sniper
Problem 1: Short range
Currently, it is possible to reduce his terror radius to be smaller than his firing range. That means he can shoot at survivors without them even hearing the killer. The problem with this is that it is only 18 meters in range. He needs new addons to increase his range, so that he can fire up to 48 meters away. For context, 48 meters roughly means that he can stand on the second floor of the Thompson house and shoot almost half the map.
Problem 2: Non-lethal shots
Being a sniper means taking out targets from a long range. It feels weird to impale a human with a whaling harpoon and have them run marathons immediately afterwards. The gun should either instant-kill anyone hit, or at the very least put them into the dying state.
Let's make the deathslinger fulfil his fantasy of being a sniper from FPS games.
Clown, the grenadier
Problem 1: The bottles are not useful or strong
Give him addons that convert the gas bottles into high-explosive grenades. The grenades' blast radius should be big enough to affect the entire basement of the killer shack. "Fire in the hole!"
