This game needs a challenge I propose dungeons

[secateurs]

There's a team of people making POI's, there's more than enough houses and factories in the game as it is.

 

Get a tiered mission from Rekt or Joel and travel to the location, hit the "!" and the dungeon is formed, Dungeons are immutable like the trader's POI so bring nothing but ammo and healing supplies and actually fight your way to the goal and navigate the hazards. 

Finish and be returned to the surface as the dungeon disappears.
