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) 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 enemies. Each dungeon also has other varying random factors.
Random dungeons
- This section needs expansion with all random factors of each dungeon.
As of version 1.1.1.0, there are 5 random dungeon base zones.
Water Treatment Facility
The Water Treatment Facility is a fairly large two-floor random dungeon that's always in the same place (Junkyard tunnels) if it appears. It also has a random quest tied to it, Mushroom Cove scavenger.
See the quest article for some of the random factors in this dungeon.
Low level bunker 1
Low level bunker 1 is a small bunker-themed random dungeon that can appear in low level areas before Junkyard.
Random factors include level of destruction, if the armory is blocked and if master power is exposed.
Low level bunker 2
Low level bunker 2 is a small three-floor bunker-themed random dungeon that can appear in low level areas before Junkyard. It's a robot facility with large open pit in the middle.
Random factors include the location of a key and whether an industrial bot is present.
Low level cave 1
Low level cave 1 is a fairly large cave-themed random dungeon that can appear in low level areas before Junkyard. Contains a camp with some loot and "Arena Now" Broadcasting Schedule oddity, a tiny shroom cave behind an agility check, two rubbles containing Trilobite Fossil and Obsidian Shard oddities.
Random factors include corpses that may appear in the dungeon. Access to segments of the cave, such as the camp, may be blocked off by rocks.
Low level cave 2
Low level cave 2 is a small two-level cave-themed random dungeon that can appear in low level areas before Junkyard.
Random factors include two creature types fighting near the waterfall and whether some of them survived.
