How to Add Friends on Ready or Not

Ready or Not is a tactical shooter built around coordinated team play — and that means getting friends into your lobby matters. Whether you're planning a co-op campaign run or want regular squadmates for multiplayer operations, the process for adding and connecting with friends has a few layers worth understanding before you dive in.

The Platform Layer: Steam Is the Foundation 🎮

Ready or Not is a Steam-exclusive title, which means the entire social and multiplayer infrastructure runs through Steam's platform rather than a separate in-game friends system. There is no standalone in-game friend list independent of Steam. If you want to play with someone, the starting point is always your Steam Friends List.

To add someone on Steam:

  1. Open the Steam client or overlay
  2. Navigate to your profile and select Friends > Add a Friend
  3. Search by their Steam username or profile URL
  4. Send a friend request — they'll need to accept before you can invite them to a game

Once someone accepts your Steam friend request, they become visible within Ready or Not's multiplayer interface as an available contact you can invite directly.

How In-Game Invites Work

Once your Steam friends list is populated, inviting someone into a Ready or Not session works through the lobby system:

  • The host creates a lobby (either through Play > Multiplayer or via the co-op campaign mode)
  • From inside the lobby, the host can use the Invite Friends option, which pulls directly from the Steam friends list
  • Invited players receive a Steam overlay notification and can join through that prompt

Alternatively, friends can join through the Steam Friends panel itself — right-clicking your name in their Steam friends list and selecting Join Game when you're in an active, joinable lobby.

Lobby Visibility Settings Affect Who Can Join

One variable that trips up many players: lobby privacy settings. Ready or Not lets the host control who can enter the lobby:

Lobby SettingWho Can Join
PublicAny Steam user can potentially find and join
Friends OnlyOnly confirmed Steam friends can join
Invite OnlyOnly players explicitly sent an invite can join
PrivateLobby is closed; no outside players can enter

If friends are having trouble joining, the lobby being set to Invite Only or Private is the most common cause. The host needs to either change the setting or manually send an invite.

Co-op Campaign vs. Multiplayer Mode: Different Entry Points

Ready or Not has two distinct modes where friends can play together, and they handle lobby creation slightly differently.

Multiplayer mode operates through a server browser and dedicated lobbies. Players can create open or invite-only rooms for standard missions.

Co-op campaign runs through a hosted session where one player acts as the session owner. Progress saving in co-op has historically been tied to the host's save file, meaning guests may not retain all progression. This is a significant variable — players with different goals around progression should be aware of how host-side saving works before committing to long co-op sessions.

When the Friend System Doesn't Behave as Expected 🔧

Several technical variables can cause friend invites and joins to fail:

  • Steam overlay disabled: If the Steam overlay isn't active in-game, invite notifications may not appear. Check Steam settings under In-Game and ensure the overlay is enabled for Ready or Not specifically.
  • NAT type and firewall settings: Players behind strict NAT configurations or certain router firewalls may struggle to connect to peer-hosted lobbies. Ports commonly associated with Steam matchmaking (UDP 27000–27036, for example) sometimes need to be open.
  • Game version mismatch: If one player is on a different version of the game — possible during rapid patch cycles — connection attempts will often fail silently or with a generic error.
  • Steam friends list visibility: Steam profiles set to Private or Friends Only visibility can affect discoverability, though this doesn't usually block an already-accepted friend request from functioning.

Platform and Account Variables That Shape the Experience

How smoothly this process goes depends on a few factors that vary by user:

  • Steam account standing — accounts with spending restrictions (new accounts that haven't spent $5 on Steam) have limited social features, including friend requests
  • Network environment — corporate networks, strict ISP configurations, or VPN usage can interfere with peer-to-peer lobby connections
  • System firewall rules — Windows Defender Firewall or third-party security software occasionally blocks Steam's matchmaking traffic
  • Number of mutual games — not a technical blocker, but Steam's friend request spam filters are stricter for accounts with no mutual games or history

What Changes Based on Your Situation

For a player who already has an established Steam friends list and a home network with standard settings, adding and playing with friends in Ready or Not is generally a low-friction process — a few clicks from the lobby screen.

For a player on a fresh Steam account, behind a strict corporate or campus network, or trying to coordinate with someone in a region with significant latency differences, more troubleshooting steps may be involved before sessions run reliably.

The difference between a seamless co-op session and a frustrating connection loop often comes down to which of those variables apply to you — and your friends — specifically.
