There are many types of rooms in UnderMine. These rooms include:
Normal rooms[edit | edit source]
Secret rooms[edit | edit source]
These rooms must be blown into with any sort of an explosion. If there are sparkles on a wall, it has a secret room behind it. Sparkles can be revealed with any kind of an explosion in the room. They may contain one or more Blessings, treasures, puzzles, items, and so.
Secret rooms can be bombed out of into locked rooms, and saving keys.
Crawl Spaces[edit | edit source]
Crawl Spaces are hidden underneath rocks which must be exploded to gain access. The Potion of True Sight can be consumed to see any hidden Crawl Spaces. These Crawl Spaces may contain Mr. Rat and Mrs. Rat, Kurtz, Lillyth, treasures, puzzles, items, Blessings, and Potions.
Relic rooms[edit | edit source]
Shops[edit | edit source]
Shops can contain items, relics, artifacts, and more. There are some different types of shops. The shops may be found locked.
Sacrifice rooms[edit | edit source]
Offering rooms[edit | edit source]
There is no point in doing so, but destroying the Relics does not curse the player.
Treasure rooms[edit | edit source]
Hoodie's rooms[edit | edit source]
Hoodie can be found on the first floor of every Location behind blue blocks to the north of the starting room. The blocks require the Echo Blast upgrade to bomb. The room will contain an opened crawl space that contains Hoodie. The player can teleport to the first floor of any Location that is below the current one if the player owns the corresponding map Artifacts.
! rooms[edit | edit source]
These rooms signify rooms with a quest or NPCs.
Most of these require Bombs to get into.
Boss room[edit | edit source]
The room contains the Location's Boss. The entrance to the room is a large pit in the ground. The fight beings if the boss has not been defeated on this Ascension level; otherwise, the room will be empty. The boss room's exit leads to the entrance to the next Location, and can be used as a shortcut.
Altar rooms[edit | edit source]
These rooms contain shrines. The player may pray at a shrine for a blessing at the cost of a curse, or pray to get rid of a curse at the cost of health. For more info, see Altar, Blessings, and Curses. The room may be found locked.
"Too mysterious altar" - Relic Altar[edit | edit source]
This room does not have a proper name yet. It can spawn on any floor. The room contains an altar that acts as a bank for a relic. The relic placed on this new altar is stored for future runs.
