The Ultimate Protogames is a level 50 Dungeon and is presented as a show hosted by the Protostar Corporation. The entrance is located in Malgrave near the entrance of the Hellrose Bowl.
The dungeon is divided into 6 rooms. The rooms are connected via teleporters and are only available once the current room is completed. The first, third and fifth rooms along with their respective bosses and mechanics are randomized during each playthrough to add variety to the dungeon.
