' Options' allows the user to toggle whether newly-placed rooms are assigned an event by default or toggle the visibility of adjacent doors in the 3D viewer. ' File' allows the user to create a new map, open a pre-existing map, or save the current map. The editor's other functions are covered by the options at the top of the window. Below the drop-down menu are a description of the selected event, as well as a slider which allows the user to adjust the probability of the chosen event happening. Underneath the list are a short description of the selected room, and a drop-down menu which will allow the user to select an event.

The sidebar displays a list of every room in the game, more specifically every room listed in SCP - Containment Breach/Data/rooms.ini. The left-hand sidebar has two tabs which will allow the user to switch between editing the map and viewing it in 3D. The maintenance tunnels use an all-white grid of the same size as the main facility's, whereas SCP-860-1 uses a grid with squares that are four times as large. At the top of the grid are three tabs which allow the user to switch between editing the configuration for the main facility, the maintenance tunnels and the path through SCP-860-1. When a room is placed, it will be represented by a shape inside the square depending on the type of room rooms with two entrances/exits are represented by a rectangle with two openings, rooms that have a 90º turn will be a smaller square with two openings on adjacent sides, and so on. A pink row and an orange row represent the checkpoints between the zones. The grid is divided into three colors to represent the respective zones: white for the Light Containment Zone, red for the Heavy Containment Zone and yellow for the Entrance Zone. The main section is represented by a grid, with each square representing a room.

The editor is divided into two separate sections.
