....Be more specific to what kind of a crossbow you mean? I thought this thread would've had a workshop link or two so that I could get an idea of what you mean. Unless you mean the Hl2 Crossbow which would be OP as hell if it were to be implemented, unless the damage was that of a sniper. Which would still be rather...odd.
Workshop links for weapon suggestions are what gets them suggested. Post some videos of it being used and possible weapon stats. -1 for now. The traitors have plenty of weapons at their disposal. However, I'm not against a detective with a crossbow.

-1 This seems A LOT like another version of the harpoon. UNLESS you're suggesting we replace the harpoon with this?
i mean, the harpoon is a lot like the knife, but not the same. The crossbow would be a hybrid between a sniper and a harpoon more or less
