Antag type: Hardmode traitor

[BaneOfGiygas]

instead of a separate role you could make it a toggle when you start as a traitor/in the uplink (before you spend crystals). turn on hardmode, you'll lose all your TC and get some extra objectives, but if you can complete all of them, you'll unlock ~fancy skins~ or achievement items

This is a pretty cool idea for a literal hardmode traitor, but I personally think that the separate role would be a welcome addition. Maybe add both?
