How GROUND BRANCH multiplayer works: 16-player servers, 8-player co-op, server browser (no matchmaking), joining friends, ping, and crossplay.
Ground Branch Multiplayer FAQ — Servers, Co-Op, Ping & Crossplay (2026)
GROUND BRANCH is a multiplayer game first and a single-player game second — the official FAQ calls co-op "core" to the experience, and the server browser is where the community lives. If you're new, this FAQ answers the questions everyone asks first: how many players, how to join, whether there's matchmaking, how to play with friends, how bad the lag is, and whether crossplay exists. (Short version: 16 players max, no matchmaking, invite via Steam, no crossplay — GROUND BRANCH is Windows-only.)
Here's what you'll learn:
- Player counts: 8-player co-op and 8v8 PvP, with a 16-player server cap
- How the server browser works (and why there's no matchmaking)
- How to host, invite friends, and join community servers
- The full mode list for co-op and PvP
- Latency expectations and dedicated server options
- Crossplay and platform facts

Is GROUND BRANCH Multiplayer?
Yes — unambiguously. The game supports online co-op against AI and adversarial PvP, plus a persistent community of dedicated servers. The store page's own pitch: "Whether in 8-player co-op or 8v8 adversarial game modes, GROUND BRANCH's unforgiving gameplay makes careful and calculated teamwork essential." The community hub and Discord (discord.gg/groundbranch) are the two places to find regular groups.
How Many Players Does GROUND BRANCH Support?
- Co-op (PvE): up to 8 players on one team against AI
- PvP (adversarial): 8v8 — 16 players total
- Server hard cap: 16 players
The official FAQ notes the team plans to eventually restrict co-op to 8 maximum ("16 players on a single team isn't compatible with the game's vision and map sizes") — but today, the technical limit is 16 across both modes. The 8-player cap for co-op is the recommended configuration on most maps.
Is There Matchmaking in GROUND BRANCH?
No matchmaking, and that's by design. GROUND BRANCH uses a server browser in the tradition of old-school tactical shooters — you pick a server, not a queue. From the main menu you have four online options:
- Server Browser — browse Internet servers (players vs AI or players vs players, never both on one server at once)
- Host Game — create a listen server hosted from your own PC (Internet or LAN); this is the "invite friends" path
- Join via invitation — friends can join your lobby through the Steam overlay
- Dedicated server — community-run or rented servers that persist 24/7 (see our dedicated server guide)
The Ready Room is the game's physical lobby: players kit up, check loadouts, test weapons on the range, and plan before deploying. There's no automated skill-based matchmaking — server reputation and community rules matter instead.
How Do I Play GROUND BRANCH with Friends?
Three reliable methods:
- Host Game from the main menu, set the player limit and mode, then open the Steam overlay (Shift+Tab) and invite friends from your friends list. Listen servers are also reachable from the ESC menu's Invite Friends.
- Join a friend's session — right-click your friend in the Steam friends list and select "Join Game" when they're hosting.
- Meet up on a community server — most regular groups run dedicated servers listed in the server browser or posted in the Discord.
Listen servers depend on the host's machine, connection, and uptime — fine for 2-4 friends, rough for full 8-player co-op. If you're organizing a regular group, rent a server from an official partner (Citadel Servers, PingPerfect) or set up your own with the dedicated server guide.
Co-Op vs PvP — The Full Mode List
Co-op (PvE):
- Terrorist Hunt — eliminate every enemy on the map
- Intel Retrieval — find a hidden laptop defended by enemies and extract with it
- Training — practice at Camp Peary's ranges and killhouse
- Extraction (new in V1.0) — rescue a hostage from AI captors before their morale meter depletes
- Operations (campaign) — the Prologue missions, playable online co-op
PvP (adversarial):
- Deathmatch and Team Deathmatch
- Team Elimination — one-life rounds
- Uplink — capture-and-hold the objective
- Defuse — attack/defend the bomb
- Hostage Rescue — one attacker becomes the hostage; escort to extraction or wipe the defenders
- DTAS (Dynamic Take And Secure) — one-life capture-the-flag style play
Which mode should you start with? Our missions & modes guide breaks down each one, and the how to play guide covers the basics before you join a lobby.
Ping, Lag and Server Quality
Ground Branch's ping experience is what you'd expect from a niche tactical shooter:
- Listen servers — latency equals the host's connection quality; playing cross-continent with the host means everyone inherits the worst hop.
- Dedicated servers — the standard for organized play. Official FAQ lists renting through partners as the recommended route; community servers usually note their region in the name.
- Player population — averages around 470 concurrent players with an all-time peak of ~1,800 (Steam Charts). You'll find populated servers in North America and Europe most hours; other regions mean longer browsing.
- VOIP — the in-game voice (Settings > Audio > Communications) works on top of the connection; the V1.0-era VOIP crash was patched through Hotfix 2/2.5. If voice drops out, it's a known-but-fixed class of bug — update the game and verify files.
For latency troubleshooting, a wired connection beats Wi-Fi, and hosting dedicated in your region beats joining cross-region servers. Community-run modded servers (custom missions, game modes) are listed in the browser too — see our mods guide for what they run.
Per the official V1.0 release notes, the V1.0 build fixed "issues with rounds not successfully starting in online sessions" and improved door replication — the two biggest online reliability complaints from Early Access.
Crossplay and Platforms — Is GROUND BRANCH Crossplay?
No crossplay, because there's only one platform: Windows. GROUND BRANCH runs on Windows only (the Steam store lists no macOS or Linux build, and there's no console version). That means:
- No PC vs console play, no cross-save across platforms
- No PlayStation/Xbox versions announced — the developers have only fielded questions about consoles on social media, without committing
- Steam Deck players run the same Windows build via Proton, so they share the player pool
The practical upshot: if your whole group plays on Windows (or Deck via Proton), everyone can play together regardless of storefront region — but there's no console community and none on the roadmap.
