Hub

The Hub is a location where the player can interact with NPCs or adjust settings before entering the first floor of the Facility. As the player progresses through the game, the Hub will gain more NPCs and features of various functions, but begins as a relatively bare room.

Kleines
Kleines is a friendly, talkative cat that appears in the Hub after the player's first run. He is the only NPC that remains in the Hub at all times, as he provides a valuable service to the player. Using their post-run collection of debris, the player can make purchases through Kleines that will add new items, weapons, and upgrades into their existing pools, giving them a chance to show up on the player's next run, as well as new ships and other run-altering options.

Kleines also provides helpful tips and has several unique lines of dialogue depending on the cause of the player's most recent death.

Furnishings
Accumulating debris through runs occasionally rewards new decorations for the Hub.

Jukebox
The Jukebox allows the player to listen to any song in the game that they have previously heard. Songs that have been heard before will be listed by their name, while unknown songs will appear as '???'.

If Skully is present in the Hub, his dialogue will change based on which song is currently being played over the Jukebox.

Terminal
The Terminal allows the player to customize their next run through a variety of settings. Options include choosing which ship is being played, changing the difficulty, changing run Lethality, playing a specific seed, and enabling loops. Available ships will be fully visible, while locked ships will appear as a silhouette. Most functions of the Terminal are initially unavailable and must be unlocked via various points of progression.

Bestiary
The Bestiary allows the player to view information about any enemy in the Facility that they have already encountered. Enemies are categorized by type, with the exception of mini-bosses and bosses, who have their own categories.

Currently, an enemy's info sheet contains their in-game sprite, their type, and a brief line of information or dialogue related to them in some fashion. Much of this dialogue serves to expand Monolith's lore and worldbuilding.

Mirror
The Mirror allows the player to view saved records of previous runs and rematch any boss that they have defeated. An icon next to any given boss's name indicates whether or not it has been defeated on the Hard difficulty setting. Not all bosses have a Hard mode variant, so this icon is not present for all bosses.

By adjusting settings in the Terminal before engaging a boss in the Mirror, the player can choose to fight as any unlocked ship and with any Lethality setting. The boss's difficulty is chosen upon selecting to fight them.

Trophy Table
The Trophy Table contains the player's pet Ghost and numerous trophies indicating their various achievements so far. It appears the next time the Hub is entered after Kleines arrives.

Level Completion Trophy
This trophy indicates the furthest floor of the Facility that the player has completed. The trophy has five variants (only the best is displayed):


 * Wooden: Awarded for clearing the Excavation.
 * Bronze: Awarded for clearing the Archives.
 * Silver: Awarded for clearing the Maintenance System.
 * Gold: Awarded for clearing the Bellows.
 * Diamond: Awarded for clearing the Sanctum.

Rank Trophy
This trophy indicates the highest overall rank that the player has scored after completing a run. The trophy has five variants (only the best is displayed):


 * Wooden: Awarded for receiving a 'D' rank overall.
 * Bronze: Awarded for receiving a 'C' rank overall.
 * Silver: Awarded for receiving a 'B' rank overall.
 * Gold: Awarded for receiving an 'A' rank overall.
 * Diamond: Awarded for receiving an 'S' rank overall (only rewarded if an S rank is achieved in all four categories in a single victory).

Ship Figurines
Figurines of Null and D-13 are rewarded for completing Floor 6 on the Normal and Hard difficulties, respectively.

The Watch
Completing a Floor 6, Hard mode victory as D-13 and receiving an 'S' rank overall grants the player the Watch trophy.

Pet Ghost
After fulfilling certain conditions, Kleines gifts the player a pet ghost in a glass jar. It can be interacted with, but is purely cosmetic. Hats can be placed on the ghost through Kleines' Furnish option once they are obtained by killing a ghost wearing the hat during a run.

Skully
Can appear near the Jukebox and will have dialogue dependent one whether the Jukebox is playing a song and which song is playing.

Sentinel
Has a chance to appear once any piece of furniture has been placed in the Hub. When talked to, it will comment on some part of the Hub. The comment varies per the different pieces of furniture or rankings of trophies(different carpets will receive different comments, for instance).

Bandana Hermit
The bandana-wearing hermit shares some fixed dialogue with the player upon speaking with them; they mainly just want to be left alone.

Blastcore
When spoken to, it will harmlessly explode. Once the player has found the Ribbon and spoken with Blastcore again, they will be treated with new dialogue and the Those You Could Save achievement.

In all future encounters with Blastcore in the Hub, they will be wearing the bow and will not explode, instead thanking the player for their help.

Trader
When spoken to, the Trader will allow the player to choose whether or not they would like to hear more about the story of the game. Whether or not they agree, the Trader will give some information. If the player agrees, they will give a relatively lengthy explanation for the games background, the Hub fades into a dark, star-filled room as the story is told. When the tale is concluded, the room fades to the normal Hub once again.

Tag Hermit
A hermit without a bandana. When spoken to, they will move away from the player. If the player is quick, and speaks with the hermit again and again in quick succession, they will begin hearing a noise that indicates they are accumulating a combo in their improvised game of tag.

The player's high score in tag is listed at the trophy table.

Rad Sentinel
The Rad Sentinel allows the player to spend some of their accumulated debris in order to practice hacking minigames. The more minigames the player completes in a single session, the faster and more difficult the minigames will become.

Accumulating a high score of 20 or higher grants the player the Hack Wizard achievement.
