Free This Weekend on Steam are five full games you can download and play without buying first: Borderlands 4, F1 25, MORDHAU, Surviving Mars: Relaunched and Crime Boss: Rockay City. All five promotions run through Monday, September 14, making this an unusually strong Steam free-weekend lineup.
Free This Weekend on Steam means temporary access rather than free-to-keep ownership. Once each promotion ends, you need to buy the game to continue playing, although save progress normally remains available if you purchase afterward.
Borderlands 4
Borderlands 4 is the biggest name Free This Weekend on Steam.
The first-anniversary promotion gives players access to the full base game, including the core campaign and free post-launch additions.
The Steam window runs until September 14 at 10 AM PT / 1 PM ET / 5 PM UTC / 6 PM BST.
Borderlands 4 is also discounted during the promotion, and progress earned during the free period carries into the purchased game.
If you want a co-op looter shooter for the weekend, this is the obvious first download.
F1 25: 2026 Season Edition
F1 25 is also Free This Weekend on Steam as part of EA’s September update.
The free period includes F1 25: 2026 Season Edition and the 2026 Season Pack content available through the promotion.
Steam access runs from September 10 at 17:00 UTC until September 14 at 17:00 UTC.
The September update adds the 2026 F2 Championship, sports updates, current liveries and other seasonal changes.
Progress carries over if you decide to buy the game after the free weekend.
MORDHAU
MORDHAU joins the games Free This Weekend on Steam for players who prefer medieval multiplayer chaos.
The first-person melee game is built around swords, polearms, bows, siege weapons and large battles where positioning matters almost as much as reaction speed.
The free period runs through September 14.
MORDHAU is also heavily discounted during the promotion, while double XP and Gold have been promoted around the weekend.
New players should expect a steep learning curve, but Frontline and Invasion give you room to learn without every fight feeling like a duel exam.
Surviving Mars: Relaunched
Surviving Mars: Relaunched is Free This Weekend on Steam until September 14 at 17:00 UTC.
The colony builder sends you to Mars and asks you to create a settlement that can survive resource shortages, infrastructure problems and the general inconvenience of living on a planet that would quite like everyone to leave.
Relaunched is the expanded remaster rather than the original release.
It has also received recent updates and new content, making the free weekend a useful way to see how the newer version feels before buying.
Crime Boss: Rockay City
Crime Boss: Rockay City completes the five games Free This Weekend on Steam.
The promotion gives temporary access to its mix of co-op heists, crime management and story-driven modes through September 14.
Crime Boss has received years of updates since launch, so the current version is considerably broader than its original release-day package.
It is also running one of the deepest discounts in the group, which makes the weekend a particularly cheap way to continue if the heist loop clicks with you.
What time do the Steam free weekends end?
The current promotions generally end Monday, September 14 at 10 AM PT / 1 PM ET / 17:00 UTC.
That is 6 PM BST in the UK.
Free This Weekend on Steam promotions are tied to temporary Steam licenses, so starting a download just before the deadline does not let you keep playing indefinitely afterward.
Give yourself enough time to actually install the games before the clock runs out.
Do you keep the games after the weekend?
No. These are not permanent giveaways.
The games Free This Weekend on Steam return to paid access once their free licenses expire.
Your save files and achievements generally remain, which means you can pick up where you stopped if you buy later.
Several of the games also have discounts running at the same time, but you do not need to purchase anything to use the temporary free access.
Which free Steam game should you play first?
Borderlands 4 is the strongest option if you want a big campaign and co-op shooting.
F1 25 is the pick for racing, Surviving Mars: Relaunched covers strategy and management, MORDHAU handles competitive medieval combat, and Crime Boss is the wildcard for co-op heists.
With five games Free This Weekend on Steam at the same time, the only real problem is download space and the irritating fact that weekends continue to contain only two days.
