Hosting: three clicks and a save slot
The flow is short, and every step matters.
- Play with Friends from the main menu — not Play Alone
- Choose a save slot (there are three) — this is the slot the group’s progress and unlocks live in
- Host — you land on the second floor of the lobby house
The save slot choice is the part players regret. Progress is tied to the slot, so a group that keeps switching slots keeps restarting its view milestones. Pick one and reuse it.
The two invite methods
Once you are hosting, there are two routes and they behave differently.
| Method | How | Notes |
|---|---|---|
| Second-floor terminal | Walk to the monitor with the Invite Friends sign, press E | In-game, no overlay |
| Steam overlay | Shift + Tab, right-click the friend, Invite | Familiar, but one person at a time |
The terminal is more reliable when the overlay invite option is missing — a common complaint that usually just means the friend has not launched the game yet. Invites only land reliably if the other player has the game open.
The 4-player cap and the door lock
Four total, host included. There is no way around it in the base game.
More important than the cap: the front door locks when the expedition starts. From that moment, nobody joins. That one rule explains almost every “my friend can’t join” thread — the run was already in progress, and Content Warning has no mid-session joining and no rejoin after a disconnect.
If someone drops, you finish short-handed or you rehost. There is no drop-in support.
Crossplay and friend codes
The console versions launched in April 2026 and added crossplay with Steam. Console players cannot use the Steam friends list, so the game uses codes instead.
- Host: the join code appears in the pause menu
- Joining player: Main Menu → Join Game → enter the code
- Both sides: enable cross-platform play in Options → Matchmaking → Cross-Platform Play
If the cross-platform toggle is greyed out, the standard fix is to play one match and then retry — it unlocks after the first session.
How to talk to your team
Content Warning uses built-in proximity voice chat, not a party channel. You hear teammates only when they are nearby, which is deliberate horror design — being separated means being silent, and the moment you most need to warn someone is the moment they cannot hear you.
That has three practical consequences:
- Stay in earshot. A camera operator who wanders two rooms away can film something the team cannot hear a warning about.
- Agree a fallback before the dive. Discord or another voice app is the standard workaround when proximity chat fails or when the group wants constant comms.
- Test microphones in the lobby. Voice is a core mechanic here, not a social extra; a dead mic is a player who cannot call out a monster.
There is no in-game push-to-talk setup step beyond your platform and system microphone settings.
What actually makes a co-op run work
Four players does not automatically mean four times the output, because of how scoring works.
The camera is singular. Only one camera exists and only one player can hold it. Three people cannot film simultaneously, so the group splits: one cameraman, three people making things happen.
Objects score once per day. Every player filming the same radio adds nothing after the first. Assign different objects per player per day rather than all filming the same thing.
Enemies score per individual. This is the opposite rule, and it is what makes combat footage the reliable income. Four players each filming a different Slurper is four scores.
Emotes are per-player. Each player can hold one emote, so a group of four can produce four daily emote scores.
Pre-run checklist
Before the host opens the door:
- Everyone is in the lobby — after the door opens, no one else joins
- Same save slot as last time — otherwise the group’s progress restarts
- Crossplay enabled on every client if the group is mixed platform
- Roles agreed — who holds the camera, who carries the shock stick, who scouts
- Different emotes equipped — four players, four daily scores
- Voice working — proximity chat is the core mechanic, and Discord is the standard fallback
