Steam‘s Free Weekend promotion is giving PC gamers a handful of co-op and multiplayer games to check out this weekend, with the current selection available from now until September 21 at 10 am PT/1 pm ET. For those unfamiliar with this specific Steam promotion, it essentially grants unfettered access to games for a limited time, but that access will end at its expiration time. The good news is usually there’s a discount for anyone who wants to keep playing.
There are numerous free PC game promotions on the internet, ranging from Lenovo Legion Gaming community’s giveaways and Alienware Arena to the weekly Epic Games Store games on Thursday. Steam itself has two of note, which any PC users should familiarize themselves with. Steam’s Free Weekend Promotions work as described above, but Steam’s Free-to-Keep promotions are the inverse: players can download and keep the game forever as long as they claim it by a specific date. For the games in the current promotion, though, fans will want to play them ASAP to avoid ponying up.
Steam Free Weekend Games List (September 17-September 21)
While Steam’s Free Weekend Promotion typically includes a handful of unique games, this weekend’s seems to focus on co-op and multiplayer experiences, including Diablo 4, Sea of Thieves, Last Flag, and Jump Space. Each can be played as much as folks want until September 21 at 10 am PT/1 pm ET, with the promotions lasting shortly thereafter. Alongside core info like the mentioned price and links to each free game, the items are listed below to help readers decide which games to play for the promotion.

Steam Free Weekend Game: Diablo 4
While it hardly needs any introduction, Diablo 4 is an action RPG set in the dark world of Sanctuary, where players create a character, fight through hordes of demons, collect increasingly powerful gear, and build their character around different abilities and equipment. The campaign can be played alone or with friends as players explore an expansive world, clear dungeons, battle bosses, and take on enemies tied to the return of Lilith. Once the campaign, DLC, and so on are finished, Diablo 4 also offers an extensive endgame—no one but the baddest demons in hell are getting their fill of Diablo 4 during this free weekend.

Sailing across a massive shared world is the foundation of Sea of Thieves, with players taking on the role of pirates who can explore islands, search for buried treasure, complete voyages, and battle both enemies and rival crews. Much of the game revolves around bringing treasure back safely, since crews can lose their loot if their ship sinks before they reach an outpost. Along the way, players can fight creatures such as the Kraken, fish, customize their ships, create treasure maps, and take part in a variety of seasonal events and activities.

Multiplayer game Last Flag aims to elevate the core, classic Capture the Flag game mode by making the entire match revolve around finding, stealing, and defending a team’s objective. Two teams of five players first get 60 seconds to hide their flag before the hunt begins, with each contestant bringing unique abilities that can be combined with their teammates. Cash earned during a match can also be spent on upgrades, adding another layer to the fights. Once a team captures the opposing flag, the match enters its final stage as that team must protect the stolen flag for 60 seconds while the other side tries to take it back.

Steam Free Weekend Game: Jump Space
Jump Space is a four-player co-op PvE game on Steam where players work together as the crew of a spaceship and constantly switch between operating the ship, exploring planets, and venturing into space. Missions can include random elements, so crews have to adapt as they fight enemies, salvage resources, repair damage, and keep their ship running. Players can take on different responsibilities such as piloting, engineering, and field exploration without being locked into traditional classes, while the ship and weapons can be upgraded and customized between missions. The biggest part of Jump Space is keeping everything working under pressure, adding in a nice doze of co-op zaniness.
