This was on the NBS Clan MvM Server...

No one really knew why this was happening but someone said something about a voucher ticket and a 100% chance to get a botkiller weapon

[markg]

thats one of the modes they had for halloween.

but what they said about a voucher and botkiller weapons makes no sense

Coaltown Event is a map that was released on October 26, 2012, as part of the Spectral Halloween Special update. It is designed for the game mode Mann vs. Machine. Coaltown Event is a version of Coal Town at night, with pumpkins, gravestones, and other Halloween-themed objects scattered around. It is unique in that all robots on the map are reskinned to look like zombies, though this is purely cosmetic. The map contains only 1 mission: the Nightmare mission Caliginous Caper. As it is not playable in Mann Up mode, there is no reward for completing this mission.
