Floor plan, spawners, objectives and medicae come from the game's own navmesh and level units, captured in game with a SoloPlay mod on 2026-10-23. Hold candidates and chokepoints are computed from that geometry. Hover a marker (or long-press on a phone) for details.
Triggers on this route
Bosses, captains, daemonhosts, rituals and the twins are tied to a distance along the route. They appear when the player furthest ahead passes that distance, wherever the rest of the team is. The map shows every possible spawn point. A run uses only some of them: at most one boss per section, 5 ritual sites, and one twins point. How triggers work.

Scripted fights: where to try holding
These spots are computed, not playtested. For each event objective, every reachable floor spot within 14 m of the objective was scored by four things: how few lanes the enemies from the nearby event spawners arrive through on foot, how many walls are close, how far the nearest spawner is, and how close the objective is. The score knows nothing about gunner sight lines, enemies dropping from ledges, or specials, which spawn from the normal pool anywhere. Use these spots as starting points, then trust what works.
A Decoder
19 event spawners within reach, used by these scripted events: hacking, hacking transit guard.
- A12 approach lanes (north-west, south). Walls within 3 m on 9 of 16 sides. The nearest event spawner is 9 m away on foot, and the objective is 13 m away.
- A22 approach lanes (north-east, north-west). Walls within 3 m on 6 of 16 sides. The nearest event spawner is 9 m away on foot, and the objective is 13 m away.
- A33 approach lanes (west, south-east, north-east). Walls within 3 m on 8 of 16 sides. The nearest event spawner is 6 m away on foot, and the objective is 6 m away.
Chokepoints on the route
Places where the walkable floor along the main path narrows sharply next to an open area. The width is navmesh width, which is a little narrower than the gap you see, because the AI keeps its body radius off walls.
| Along route | Floor width | Opens |
|---|---|---|
| 77 m | 1 m | between two open areas (19 m wide) |
| 151 m | 2.5 m | between two open areas (29 m wide) |
| 271 m | 2 m | between two open areas (30 m wide) |
| 444 m | 2 m | between two open areas (26 m wide) |
| 574 m | 3.5 m | between two open areas (27 m wide) |
| 619 m | 4.5 m | between two open areas (22 m wide) |
| 693 m | 4 m | between two open areas (38 m wide) |
| 725 m | 3.5 m | between two open areas (30 m wide) |
| 846 m | 4 m | between two open areas (56 m wide) |

What players report
Collected from Reddit, Steam, the Fatshark forums and guides. Each tip links its source and says how many sources agree. Not verified in game.
- Opening tunnel and the big room after it. Called the hardest part of the map in Havoc: “Tunnel and big room after it. Most runs end here.” The Havoc OP says the same about “The tunnel and the area after it”. multiple sources agree - u/Enclave_Liberator, OP of “Worst maps on Havoc”
- Room before the mid event (rituals). “The room before mid game event. There are possibility for 3 dh ritual and 2 of them are buggy”. single source (Havoc) - u/madao123451
- End boss on the train (may be patched). “if you reach the door where he will spawn before he gets out the train sometimes he stays there shooting and the door closes again and kills him. Not sure it’s always possible to pull it off”. A second commenter describes the same door interaction. single source (one thread, two comments) - u/Shakaww, u/Jazzlike-Attorney-96

Objective names are the game's internal ids, in the order the mission file lists them. Mid and end events are scripted horde moments; plan your hold position for those.
How to read this map
The line is the mission's main path, taken from the level data. It is the exact path the director measures your progress along. Specials, horde quotas and captains are all paid for in metres along this line. Its colour shows height, so a sudden change from dark to light is a climb.
The shaded floor is the navmesh: everywhere the AI can walk, which is almost everywhere you can walk. Lighter floor is higher up. Event spawners are the closets, vents and doors scripted events pour enemies out of. Horde spawn points (off by default) are where the director may place ambient hordes along this route.
Hatched red shapes are drop-offs and kill zones. Grey outlines are invisible walls that keep players on the route. Walls and rooms are not drawn yet; the main path follows the walkable route through them.
