If it's not too much work on Halloween for one day only or for one server restart cycle, we switch the map to the old gmod TTT minecraft server map. I think a lot of our best memories on gmod were made on that old map and it would be really fun for Halloween to revisit it. We could all go to the wooden house, (different factions can lay claim to a traitor trap) we could pvp around the light house and the nether, have a diddy party in the traitor room and cops could arrest people and lock them in the test chamber. I don't think we would need to do much work besides spawning a gun npc, an atm and a car spawn and just let TTT take natures course from there.
