The Ultimate Achivement Map.

[A throwaway number 423.]

This is a throwaway account because I couldn't find anything on the manner so I will post my idea here.

I imagine a map, that has 520 separate rooms to finish 520 separate TF2 achievements. I imagine putting some sort of challenge between each room so that it could be like a single player game where you win by getting every achievement.

I don't think it is really possible to get all of the achievements in one map, when you include stuff like Halloween, MvM, Foundry and Doomesday. That is a good Idea, though. Maybe making a super map that accomplishes what other achievement maps have done and then some.
