**Owner decision, 2026-09-19.** After reading the inventory of the rooms as they were built, the owner found a pattern of things to interact with that gave the player no reason to care (the ward window photograph, the fault lamp, the bridge rack, and more), and said: "it seems like the best solution is for me to design each room manually." Asked how to begin, he answered: "let's start with an empty station and add the rooms as I design them", and "I will write them here. you will transfer them both to code and the wiki."

So this page is the home of the station's rooms from now on. **Every room below is the owner's own card.** The implementer builds exactly what a card says, and asks where a card is silent instead of filling the gap. The older room pages of this wiki ([Station Room And Module Inventory](/Hold%20The%20Flood/Station%20Room%20And%20Module%20Inventory), [Encounter And Mechanism Placement Inventory](/Hold%20The%20Flood/Encounter%20And%20Mechanism%20Placement%20Inventory), [First Expedition Options](/Hold%20The%20Flood/First%20Expedition%20Options)) describe an earlier design. They are not what the game contains.

The first slice built the set-ups of the old design and not the pay-offs that made them matter. The fault lamp was the sign of a power leak that cost the player nothing. The isolation bridge was the fix, and fitting it was meant to let the ship find the ward behind the window, which was meant to start the rescue; in the game it changed one line of text. The window photograph had no use even in the design. A thing the player can use, with no reason to use it and nothing visibly different afterwards, reads as a broken game. The record of the old rooms, in plain words, is here: https://claude.ai/artifact/YE2xxDvC7nCt2eNqCqboC5

One card per room, in the manner of the owner's item card on [The Pack](/Hold%20The%20Flood/The%20Pack).

- **Why the player goes there.** One sentence.

- **Doors.** Which rooms it joins.

- **Things in it.** For each: what it is; the key; how many seconds; what is needed first; what is different afterwards that the player can see; once, or every time.

- **Enemies.** Kind; how many stand in the room; how many hide, and behind what; what lets them out; how fast they come; how to stop them.

Anything outside this list is new code, which is fine; its size is stated before it is built.

- **Rules that hold everywhere:** every press of E answers; the only text in a room is the prompt on the thing the astronaut is locked on, and the box on the left that says in plain words what it is and what can be done with it; every job shows a bright bar while E is held; every word the player reads is plain.

- **North door:** locked. **Press E:** it answers "LOCKED", in red, at the door. When the right password is typed into the panel beside it, the two leaves slide apart into the wall and the door stays open for good: through going home, dying, saving and loading *(staying open for good is my choice; the card says only that it opens)*. The game saves at that moment.

- **The control panel:** on the north wall, to the left of the north door as seen from inside the room, 2.3 metres from the middle of the doorway. A wall terminal about one metre wide and a metre and a half tall, hung 0.8 metres above the floor: a dark metal body, a glowing screen with lines of writing and a blinking cursor, a lamp bar above the screen, a keypad with a red and a green key, a yellow and black strip along the bottom, and a cable running up the wall towards the door. Screen, lamp and the light it throws are **red while its door is locked and green once it is open**. It is **one prefab**, `Resources/Prefabs/ControlPanel`, with its own small script; every panel in the game will be this prefab, and what a given panel does comes from the content, not from the prefab. *(The look is mine; the prefab can be edited by hand in Unity, or rebuilt from the menu Flood > Rebuild Control Panel Prefab.)*

- *How it got here (owner, all 2026-09-19).* First version, flat lettering in a plain frame: "I am sure you can make the neon sign look better. Give it a proper font, place it better on the wall, that kind of thing. right now it looks almost like a 16 bit game." Second version, letters of bent glass tube on a dark board leaning out on brackets, with a soft glow and a stutter like a struck tube: "they both looks much better, but the neon sign now looks a little bit too much like a commercial sign. Like it's from Las Vegas brothel or Broadway Street. I want it to look more like a panic sign." Third version, the alarm sign, in a deep housing that stood 8 centimetres off the floor and leaned out at the top: "it now looks much better, but last small problem: the sign looks like it's placed on the floor, not on the wall." Two faults of position: its foot was so low and its box so deep that, seen from above at a slant, its lower edge was drawn in front of the line where wall meets floor; and it leaned the wrong way, turning its face down and away from a camera that looks from above. This is the fourth: flat on the wall, hung clear of the floor. The capitals, the two lines, the hazard stripes and the beacons are the implementer's choices.

- **Place and size:** 60 metres long (east to west) and 10 deep, joined to the Dock's west door by its own east door. The HUD names it "Western Promenade".

- **Doorways:** one in the middle of the east wall (open, into the Dock), one in the middle of the west wall, and three on the north wall, 15, 30 and 45 metres along it, so the four stretches of wall between and beside them are equal *(my reading of "equally spaced"; the other reading would be 10, 30 and 50)*. The west one and the three north ones have no room behind them yet, so they show as sealed doorways ("Sealed doorway. No room behind it now."), like any doorway the cards say nothing of.

- **When:** three seconds after the astronaut first walks in on a trip, the first one appears. Walking out and in again does not start it twice, and once started it goes on whether the astronaut stays or leaves *(mine: the card says only when it starts)*.

- **Where:** at a place in the room the camera does not show, picked at random from those just past the edge of the screen (no more than 6 metres beyond the nearest such place), so they walk in from every side that has an unseen part; never closer than 8 metres to the astronaut. When the camera shows the whole room, the place farthest from the astronaut. *(The 6 and the 8 are mine.)* They know where the astronaut is from the moment they appear.

- **How fast:** one every two seconds at first, climbing steadily to five a second over **60 seconds** *(the 60 is mine for "slowly")*.

- **The pause:** while 15 enemies are alive inside the room, nobody new appears. Any enemy in the room counts, whoever sent it *(my reading of "15 enemies in the room")*. Time spent waiting is not made up for by a burst afterwards.

- **The end:** when 50 of this room's enemies have been killed, no more come. Those still alive must be killed too: between 50 and 64 come in all. When the last one falls, the chest appears.

- **The kind: weak and slow.** A new, fourth kind, with no name yet. *(All its numbers are mine:)* walks 1 metre a second, as slow as the slowest thing in the station (the astronaut walks 4), dies from any one hit (health 1; the Service Gun does 5), hits for 5% of the astronaut's health after a one-second wind-up, then rests 1.8 seconds; a little smaller than the others and paler.

- **The chest.** It grows out of the floor in the exact middle of the room, with a soft gold light and a thin glowing outline round it, and the message line says "A chest has appeared in the middle of the Western Promenade." *(The words and the look are mine.)* Somebody standing on that spot is moved aside first.

- **Press E** while locked on it: it opens and gives a second Service Gun, the same gun the astronaut starts with; the pack opens so it can be placed. If it does not fit, it stays in the chest to be taken later; on a later trip it is still in there once the chest is won and opened again, and it cannot be got at before that. Opened and emptied, the chest says "empty" and its light goes out.

- **Every trip starts the room over** *(mine: the card does not say; it follows the game's standing rule that enemies are back on every new trip)*: going home or dying and coming back brings the enemies and the chest again, with another pistol in it.

- **Nothing else:** no jobs, no items lying about, no panel. Nothing on screen says that the enemies have started, how many are left, or that they have stopped coming *(not asked for; easy to add)*.

- **A game saved before this room existed gets the room:** the station is laid out as the content has it now, not as the save remembered it, and the message line says "The station has changed since this game was saved. Its new rooms are there now."

**New building blocks this card added:** a side of a room can be a row of large decorated windows onto open space; a room can fill with enemies by the rules described under "Rooms that fill with enemies"; a fourth, weak and slow kind of enemy; a chest that appears when a room is won and gives an item; open space is no longer drawn over a neighbouring room.
