Sectors in End of Abyss
Nine named sectors show up between the weapon routes and the trophy list. Six of them have a floor or a role you can walk. Factory West, the Waterworks, and the Containment Sector are named only by SCU trophies, and no floor is stated for them. The graph on this page draws only the links the notes actually support: Outer Sector with Maintenance in both directions, Habitation Sector toward the Infirmary, and the Lower Levels toward the Infirmary.
There is no coordinate grid. A shuttle name plus a floor tag is the location system. F1 and F2 are above, B1 and B2 are below. When a sector cell says the floor is not stated, leave that deck blank instead of assigning a number from the trophy order.
| Sector | Floors | What you do there |
|---|---|---|
| Outer Sector | F1 and B2 | Treated as the first area. The Support Gun is an optional find on B2 after you come back. |
| Habitation Sector | F1 | Riot Breaker sits near Security on the way to the first shuttle. The Infirmary lift is to the right of that shuttle. |
| Factory East | F2 | Security Rifle room off the larger room near the Factory East shuttle. Needs the Factory Keycard and an Explosive Charge. |
| Maintenance | F2 | An Explosive Charge in the floor outside the safe room opens a drop toward the Outer Sector shuttle. |
| Lower Levels | F1 | Treated as the final area. The Incinerator is on the right-side story path. Burning the Parasitic Spire yields the Infirmary Key. Descent Initiated marks the trip down. |
| Infirmary | F1 and B1 | Optional late area opened with the Infirmary Key. Restricted Access Keycard on F1 opens B1, where the Particle Disruptor sits past a boss. |
| Factory West | not stated | SCU: Factory West asks you to override the SCU there. No weapon pickup is tied to this name. |
| Waterworks | not stated | SCU: Waterworks asks you to override the SCU in the Waterworks. No weapon pickup is tied to this name. |
| Containment Sector | not stated | SCU: Containment Sector asks you to override the SCU in the Containment Sector. No weapon pickup is tied to this name. |
The loop you can draw
Outer Sector and Maintenance are the only pair marked in both directions. You leave the opening wing, and later a hole in the Maintenance F2 floor drops you back toward the Outer Sector shuttle. That return is how the optional Support Gun on Outer Sector B2 becomes reachable after the Lower Levels, instead of during the first stroll through F1. If the graph looks thin, that is because Factory East does not have a drawn edge to Maintenance or to Habitation. The shuttle network is the missing line, and Shuttle Network Restored is the trophy for switching all of those stations on, not a new sector name.
Habitation Sector points at the Infirmary and nowhere else on this graph. The lift is to the right of the first Fast Travel Shuttle, and it stays a locked promise until the Infirmary Key exists. The Lower Levels also point at the Infirmary, because that is where the key is made. Burning the Parasitic Spire on Lower Levels F1 with the Incinerator is the link. There is no edge from the Infirmary back to those wings on the graph, even though you can of course ride a shuttle out once the stations work. The arrows are acquisition links, not a full subway map.
Floors that have a weapon
Outer Sector is F1 on the way in and B2 for the Support Gun. Habitation is F1 for the Riot Breaker and for the shuttle that leads the eye toward the Infirmary lift. Factory East is F2 for the Security Rifle, in a small room off the larger room near that wing’s shuttle. Maintenance is F2 for the charge hole, not for a gun of its own. Lower Levels is F1 for the Incinerator on the right-hand story path. The Infirmary is F1 for the Restricted Access Keycard and B1 for the Particle Disruptor after a boss and a burned wall.
Read those floors against the weapon page when you are holding an Explosive Charge and deciding which wall earns it. The Security Rifle wall and the Maintenance drop are the two charge spends the sector notes name. A third charge use, the hole before the Support Gun, is the same return trip described from the Outer Sector side. Do not spend your last charge on a cosmetic crack if the Security Rifle is still behind plaster.
SCU wings without a deck number
Factory West, the Waterworks, and the Containment Sector each have one bronze trophy: override the SCU in that place. They do not have a weapon, a shuttle sentence, or a floor. Grouping them under the other six sectors would be a guess. Leave them as their own nodes with the floor cell set to not stated, and hunt the override when you are already sweeping for Master Explorer, which is a visit to every room, and for the three SCU rows themselves.
Mainframe Restored, reboot the System Protocols, is a separate hidden bronze and is not pinned to one of these three names. Power Online is the Reactor Core, and Waste Management is draining the Reactor pool. Those two sound like a utilities wing, and the Waterworks name is the closest label, but the trophy text does not say the reactor sits in the Waterworks. Keep the reactor tasks on the trophy table and the Waterworks task on its own SCU row until a route actually joins them.
Descent Initiated is the hidden bronze for going to the Lower Levels, so the final wing is marked twice: once as a place with an Incinerator, and once as an arrival. Unexpected Arrival, the experimental Restoration Pod, is not given a sector either. When a trophy refuses a floor, the sector page refuses one too. Use the stills on this page for the look of the pipe runs and the lit machinery, then go back to the graph before you plan a shuttle hop.
