Random locations

Random dungeons are new type of content introduced in Underrail version 1.1.1.0.

Mechanics

Random dungeons do not pop up like random events do. They are either there from the beginning of a playthrough, integrated and continuous with the static map, or they are not. All playthroughs will have at least one random dungeon, rarely up to three. Random dungeons can also be chained so that one random dungeon leads into another.

They should be as indistinguishable from regular areas as possible: A random dungeon will modify one or more zones by adding a small fragment into the map that serves as the dungeon's entrance. Usually, any entrance fragment can lead to any random dungeon of matching type (eg. a trapdoor will connect to a ladder, cave exit to west will connect to cave exit to east) but some random dungeons always appear in the same place.

In addition to random loot like in static areas, every random dungeon has randomized entrances and other varying random factors.

Random dungeons

As of version 1.1.1.0, there are 5 random dungeon base zones.

• Low level bunker 1 is a small bunker that can appear in low level areas before Junkyard.
• Low level bunker 2 is a three-floor robot facility that can appear in low level areas before Junkyard.
• Low level cave 1 is a fairly large, but possibly partially blocked, cave that can appear in low level areas before Junkyard.
• Low level cave 2 is a small two-level cave that can appear in low level areas before Junkyard and may lead to other random dungeons.
• Water Treatment Facility is a fairly large and complex two-floor facility that's always in the same place (Junkyard tunnels) if it appears. It also has a random quest tied to it, Mushroom Cove scavenger.
