Free on Steam means free: no trial, no month of access, nothing to buy before you can play with friends. The catch is usually the server. Most free games drop you into a queue with strangers, and the good ones let you run your own. This page splits them that way. First the free games you can put on a private server, then the big free multiplayer games that only run on the publisher's own servers.
Free games you can host a private server for
Everyone installs the game for nothing, you put up a server, and the group plays on it alone. These are all on our deploy pages, so the server is a few clicks and it is billed by the hour while it runs.
- Counter-Strike 2: 5v5 bomb defusal, free since 2018 and still the one everybody already has. On your own server you get the match you asked for: no queue, no strangers, bots to fill out the teams, and any Workshop map you like. Steam. Host a server.
- Team Fortress 2: Nine classes, Payload and King of the Hill, and enough silliness that a mixed-skill group still has a good time. A private server also skips the bot problem that public Casual has. Steam. Host a server.
- Sven Co-op: Half-Life campaigns played co-op with up to 32 people. Pure PvE, nobody is competing with anybody, which makes it the easiest sell for a group that does not play shooters. Steam. Host a server.
- Zombie Panic! Source: Survival horror where one player starts infected and everyone they kill joins the horde. The odds flip as the round goes on, so the last human alive is genuinely under pressure. Steam. Host a server.
- Fistful of Frags: Wild West shooter with six-guns, dynamite and whiskey. Rounds are short and daft, which is what you want at 1am with eight people. Steam. Host a server.
- Pirates, Vikings & Knights II: Three factions who all hate each other, mostly shoving people off ledges. The mode comes from the map, so one server can rotate between objective, capture and deathmatch nights. Steam. Host a server.
- SCP: Secret Laboratory: Multiplayer horror in a containment breach: some players are staff, some are D-class, some are the things in the cells. It needs bodies to be good, so it suits a big group. Steam. Host a server.
- Alien Swarm: Reactive Drop: Top-down co-op for up to eight. Ammo is scarce, friendly fire is real, and the aliens come out of the vents. A calm, tactical pick that runs on anything. Steam. Host a server.
Free multiplayer games you cannot host yourself
These are free and worth your evening, but they run only on the publisher's servers. There is no dedicated server to put up, so a group plays them through a party or a custom lobby instead.
- Apex Legends: Squad battle royale with movement that rewards practice. Three-player squads, so it fits an odd-numbered group badly and a group of three perfectly. Steam.
- Marvel Rivals: 6v6 hero shooter. Easy to pick up, and the roster does most of the work of explaining what your job is in a fight. Steam.
- Overwatch 2: 5v5 hero shooter with a custom-game browser, which is the closest thing here to a private server. Steam.
- THE FINALS: Team heist shooter in fully destructible arenas. Loud, fast, and best in threes. Steam.
- Warframe: Co-op PvE with a decade of content behind it. Four-player squads, and a friend who already plays makes the first week far less confusing. Steam.
- Dota 2: The whole game, free, no hero paywall. A five-stack of friends is the only sane way to start. Steam.
- Brawlhalla: Platform fighter with local and online lobbies. The one on this list a non-gamer can be competitive at within ten minutes. Steam.
Why bother with your own server for a free game
- Nobody else joins. No smurfs, no one leaving after two rounds, no vote-kicks.
- You pick the map and the mode, including Workshop maps a public server would never load.
- Bots fill the empty slots, so four people can still play a mode built for sixteen.
- Everyone gets a similar ping, because you pick the region near your group instead of near the host.
- Nobody has to stay online as host, and nobody touches their router.
What it costs
The games above cost nothing. The server is paid by the hour and only while it is up, so a two-hour session is a couple of dollars split across the group. One small server a week is free, which covers a short evening on any of these outright.
