Hello, I am currently looking for a custom zombies map I used to play. It involved a safe room at the start and no round progression. You would enter a portal and be taken to an arena to fight zombies to gain points. You could then leave and go back to the safe room to upgrade your character, guns, and health.

Some things I think it included:
Boss Fight?
Castle themed
Maybe a buy able ending.
A seperate menu.
I think I first found it from a you tuber play through but I don't remember who.

Any name or suggestion would help!
