The short answer
Yes, We Were Here Tomorrow has full cross-play. Steam, PlayStation 5 and Xbox Series X|S players can team up together, confirmed by Total Mayhem Games' official announcement. Platform choice does not restrict who you can play with.
The non-negotiable requirements
Before anything else, three facts:
- Two players. The game is two-player online co-op. There is no solo mode and no AI partner.
- Two copies. Each player needs their own copy of the game. One purchase does not cover both seats — see the price guide for the launch-discount math.
- Online connection. This is online co-op; both players need a working internet connection for the full ~15-hour campaign (see How Long to Beat for session planning).
Setting up cross-platform co-op
The exact in-game menu flow for inviting a cross-platform partner is pending live-game verification — this page will show the confirmed click path once it is checked. The standard shape of cross-play setup in releases like this is:
- Both players install the game and sign in to their platform accounts.
- One player creates a session and receives an invite code or lobby link.
- The partner enters the code on their own platform to join the same session.
- Confirm voice chat is working before you begin the first puzzle (see below).
The four steps above are the standard platform procedure, pending in-game verification for this title. If a step does not match what you see on screen, follow the game's own prompts — the game is the authority, not this page.
Platform accounts
Cross-play titles generally require each player to be signed in to their platform's online service (Steam, PlayStation Network, or Xbox network). Whether this game also requires a separate Total Mayhem Games account or a platform subscription tier for online play is not yet confirmed. If the game asks you to create an account at first launch, that is normal — create it and continue.
Voice setup: do this before your first puzzle
The We Were Here series is built on asymmetric information: each player sees things the other cannot, and progress depends on describing them precisely. Voice communication is effectively mandatory.
- Use a voice channel outside the game or the game's own chat — whichever is clearer for your pair. Test it before you start playing, not after your first stuck moment.
- Headsets, not speakers. Your partner's speakers feed their game audio back into their microphone. In a game about careful listening, that echo costs you.
- Agree on naming conventions early. "The thing on the left" fails the moment your partner's left differs from yours. Describe by stable features — color, shape, position relative to fixed landmarks — and confirm you are looking at the same thing before theorizing. The stuck-help guide expands this into a full rescue method.
- Walkie-talkie rhythm. The series' signature interaction pattern is turn-based describing: one person talks through what they see while the other listens and asks questions, then you swap. Resist the urge to both talk at once.
Troubleshooting: when you cannot connect
These are general connection checks, not game-specific fixes — apply them in order:
- Both on the latest version. Cross-play sessions fail when the two builds differ. Check for updates on both platforms.
- Restart the session from the host side. Have the host close and re-create the lobby, then re-send the invite.
- Check NAT and firewall settings. Strict NAT types on consoles and aggressive PC firewalls are the most common silent blockers for peer connections.
- Try the same platform pair again after a router restart. Boring, but it resolves a real share of connection failures.
- Check official channels for outages. If nothing works for either of you, the problem may be server-side.
If a troubleshooting step references an in-game menu you cannot find, that specific detail is part of the pending live-game verification noted above.
Session practicalities for cross-platform pairs
- Input differences do not matter much. The game is about communication, not reflexes, so controller-vs-keyboard is not a competitive concern.
- Time zones are the real boss. A 15-hour campaign across two schedules is a logistics project — see the session-planning section in How Long to Beat.
- Shared notes help more than screenshots. Screenshot tools differ by platform; a shared text note with codes and symbols works for everyone. The beginner tips page covers this habit.
