- Backrooms: Code Yellow is a 1-6 player co-op investigation game set in the infinite Backrooms
- Core loop: spawn in, open the gate at the terminal, complete two assigned tasks, return alive
- Main threats: Still Life monsters appear periodically; avoid them rather than fight
- Co-op note: joining in-session was removed in Patch #9; use save/load to add players
- Best practice: track your route visually, since the map layout stays consistent
Gameplay Overview: What a Shift Looks Like
Backrooms: Code Yellow places you and up to five coworkers inside a seemingly endless office complex. You are an employee, not a hero. Your job is to investigate, collect data, and get back out. Every run follows a recognizable rhythm, which makes the walkthrough straightforward once you understand the pieces.
Video Highlights:
- Runs begin with two tasks displayed in the bottom-left corner
- The gate must be opened at the terminal before you can leave the starting area
- The map layout does not change, which rewards learning the layout
- Still Life monsters appear periodically and must be avoided
The game is currently in Early Access on Steam, and the developer ships frequent patches. As of Patch #9, joining a game already in session has been removed to fix multiplayer replication problems, so assemble your team before departure.
You are collecting data and items, not clearing dungeons. Treat every run like a contract job: enter, document, grab what you need, and extract before a Still Life finds you.
Step-by-Step Walkthrough: From Spawn to Extraction
This is the standard route for a successful shift, whether you play solo or with a full crew of six.
Read Your Tasks at Spawn
Check the bottom-left corner of the screen. You are assigned two tasks per run. Read them before moving so you can plan a route instead of wandering.
Open the Gate at the Terminal
Walk to the terminal in the starting area and turn on the gate. This unlocks access to the wider complex. Do not leave your crew behind at this point; the gate is your anchor to safety.
Navigate and Complete Tasks
Head out and complete your two objectives. The map layout stays consistent between runs, so mark landmarks such as furniture clusters, unusual rooms, and intersections to avoid getting lost.
Avoid the Still Lifes
Monsters appear as frozen, still figures dressed in streetwear or office uniforms. Some walk, some run when triggered. Keep your distance, do not linger in their line of sight, and reroute if one blocks your path.
Return Alive
Bring your collected data and items back to the starting area and complete the shift. Saving lets you resume later, which matters since the complex is effectively endless.
You can no longer join a game in progress. To add a player: save the game, exit to menu, create a lobby, load from the save, then invite them.
Still Life Monsters: Threat Behavior
Monster variety is still growing during Early Access, but the current threats share a few behaviors you can exploit.
| Behavior Type | Description | Threat Level | Recommended Response |
|---|---|---|---|
| Walker | Slow, patrol-style movement | Low | Keep distance, slip past when it turns away |
| Runner | Stands still, then sprints at you | High | Break line of sight, reroute through doorways |
| Frozen Still | Never moves, blocks paths | Low | Walk around carefully, do not touch |
| Door Closer | Shuts doors behind you | Medium | Watch for self-closing doors; they can disorient your route |
This is an investigation and collection game. There is no meaningful combat answer to the Still Lifes. Evasion and awareness keep you alive.
Players report doors closing on their own, which creates a disorienting deja vu effect in repeated room layouts. Leave items moved or furniture repositioned along your path to build personal landmarks.
Items and Equipment Reference
Your toolkit is small but purpose-built. Items are scattered across the complex, and some tasks reference specific gear.
| Item | Function | Usage Tip |
|---|---|---|
| Tape | Data collection medium | Note: a Patch #8 fix resolved the stuck "Remove Tape" prompt; tape occasionally not appearing for other players is a known issue |
| Tripod Camera | Records footage for tasks | Patch #7 fixed it not being destroyed on pickup; model is now better optimized |
| Terminal | Opens the gate, manages save data | Always your first and last stop in a run |
| Collected items | Task objectives and loot | Carry only what your tasks require to stay mobile |
Efficiency Runner
- Two tasks only, minimal carrying
- Fastest extraction time
- Best for solo play
Data Collector
- Grab every tape and item along the route
- Higher value per run
- Needs a crew for safety
Scout Role
- Maps landmarks and routes
- Watches for Still Lifes
- Ideal for the most experienced player
With up to six players, split duties: one scout ahead, a pair on tasks, and the rest carrying loot. Coordination matters more than speed.
Common Problems and Fixes
Because the game is in active Early Access development, expect rough edges. Here are the issues players most frequently report and how to handle them.
| Problem | Cause | Workaround |
|---|---|---|
| Cannot join friend mid-run | Patch #9 removed in-session joining | Save, exit to menu, create lobby, load save, invite |
| Tape not visible to teammates | Known bug under investigation | Host picks up the tape; communicate verbally |
| GPU at 100% on launch | Optimization still in progress | Cap framerate via driver software; monitor temps |
| No key remapping | Settings menu currently limited | Laptop players report LMB+RMB camera issues; external mouse recommended |
| Fake door prompts on lamps | Interaction raycast glitch | Reposition your view and retry the correct object |
| No player name display | Missing UI feature | Use voice chat to identify teammates |
Multiple save slots are a requested feature. For now, save before risky deep runs so a wipe does not erase a long expedition.
Pre-Shift Checklist:
- Read both tasks before leaving spawn
- Open the gate at the terminal
- Assign roles across the crew
- Mark landmarks as you push deeper
- Save before every risky extension run
FAQ
Q: Can you play Backrooms: Code Yellow solo?
Yes. The game supports 1-6 player co-op, so solo play is fully possible. Solo runs favor the efficiency approach: take only your two assigned tasks, move carefully, and extract before Still Life activity increases.
Q: How do you invite a friend to an existing run?
Since Patch #9 removed joining in-session games, you must save the game, exit to the menu, create a lobby, load from the save, and then invite your friend from the lobby.
Q: Does the map change between runs?
No. The map layout stays consistent, which many players consider accurate to the Backrooms concept. Use this to your advantage by memorizing landmarks and building reliable routes.
Q: Is this Backrooms: Code Yellow walkthrough affected by patches?
Yes. The game is Early Access and receives frequent patches, such as Patch #7 fixing the tripod camera and Patch #8 fixing the tape interaction bug. Check the official Steam community page for the latest patch notes before deep runs.
