Secret rooms and underground or alternate routes are reported in current MM2 of The Locust coverage, but no verified complete list or permanent entrance map is available. A useful hidden-room route starts from a stable landmark, uses normal movement or interaction, and can be reproduced without clipping through unfinished geometry.
Search where the map language changes
Look for unusual wall gaps, vents, windows, stairs below the main level, doors with prompts, repeated symbols, rooms behind familiar routes, and connections visible from another floor. Do not press against every wall during an active chase. Search when the Locust is elsewhere and keep a known return route.
Compare the entrance with nearby architecture. A deliberately framed vent or door is stronger evidence than a seam between assets. A dark space behind an unloaded wall may be an unfinished area rather than a secret.
Reproduce a normal entrance
Start from a named or visible anchor and write each turn, elevation change, and interaction. Enter using the standard Roblox client. Leave, return, and repeat in the same build. If the route works only after a jump glitch, camera clip, exploit teleport, or collision failure, label it as a bug and do not recommend it as a player route.
Record whether the entrance is always open, role-specific, objective-gated, item-gated, event-driven, or one-way. Unknown requirements should remain unknown until the live UI or repeated play supplies them.
Decide what the room is for
A hidden space can be a route connector, hiding place, objective area, event room, unfinished zone, or purely visual detail. Watch for a normal interaction, inventory change, objective update, or safe exit before assigning a reward or purpose.
Do not call a room safe because the Locust failed to enter once. The monster may not have seen the route, may have abandoned the chase, or may have been affected by a bug. Test access through ordinary rounds.
Use a secret during a chase
Only use an entrance you can reach without stopping at a complex interaction. Break sight before approaching so the monster does not learn the route immediately. Know whether the exit returns to another zone or traps you inside.
If the secret has one entrance, treat it like a dead-end hide. If it connects two areas or layers, it can reset the chase. The route value matters more than how hidden the room looks.
Avoid the other Locust game’s item chain
Search results often mix MM2 of The Locust with House of The Locust, a separate Roblox experience. Routes involving colored cubes, wire cutters, keycards, and a green EXIT are associated with that other Universe and are excluded here. Verify Place ID 113385977463481 before following any hidden-room instructions.
Ordinary Murder Mystery 2 map secrets also do not automatically transfer. Similar architecture can be a visual starting point, but the entrance, collision, and purpose must work in the target experience.
Secret-room record
If the route disappears
Return to the stable anchor and confirm the correct floor. Check whether the round objective or item state differs. If the entrance stays closed, treat the old route as version-limited and use another loop. Do not force it through collision.
Compare the failed attempt with your last successful record: same map, server generation, role, carried item, objective stage, and visible prompt. Change one condition at a time. If ordinary players cannot reproduce the entrance in fresh servers, archive the route as an older observation instead of presenting it as a current shortcut.
Check Updates for official map changes, Hiding Spots for normal recovery routes, and Key Locations if the entrance appears connected to an objective.
Confidence
Secret and underground areas are Community reported. Specific entrances, requirements, monster access, rewards, and permanence remain Needs in-game testing until reproduced in the normal current experience.
