Guild Wars 2

A dungeon that can be one of the monthly events that has multiple levels within it and relevant to the theme.

Maybe have a new section released each week.

Saved progress, so you don’t have to redo the entire dungeon again once you have finished an area.

Dungeon doesn’t necessarily have to be harder as you go to a different section, just something different and maybe have transition as to the type of mobs you are fighting.

One idea is for this Flame and Frost theme. A section be dredge, another be Flame legion then you have sections that provide a mix of both.. or none (maybe a travel point between the two that is unused because of w/e is lurking there).

The entire dungeon as a whole could be an intricate layout of enemy camps/bases with options to which section you want to enter. (Like a maze)

good idea! like a certain point in the dungeon ( like a magical sphere that records you’re progress up to that point.) make it challenging a bit linear and great bosses (big ones to) !
