Borderlands 4
Borderlands 4 takes the looter-shooter series to the new planet of Kairos, where four Vault Hunters become caught in a conflict against the authoritarian Timekeeper. As expected, the game focuses heavily on ridiculous weapons, character builds, skill trees, and explosive combat.
The full campaign can technically be completed during the free period, although you'll have to put in some serious hours to do it.

It's a particularly good game to try during the Free Weekend if you're looking for a co-op shooter to play with friends.

How to Play These Steam Games for Free
You don't need to purchase any of these games to play them during the promotion. Simply:
- Open Steam and sign in to your account.
- Search for the game you want to try.
- Open its Steam store page.
- Select the Play Game option.
- Download the game and start playing.
Remember, you must play these games before September 14 at 10 AM PT / 1 PM ET. Once the Free Weekend promotion ends, you'll need to purchase the game to continue playing.
Don't Confuse Steam Free Weekends With Free Games
Steam has two different types of promotions that can easily be confused.
Free Weekend games let you play the complete game for a limited period. You don't need to purchase them during the promotional window, but you also don't keep access after the event ends.
Free-to-Keep games, on the other hand, can be claimed during a specific promotional period and remain permanently in your Steam library.
So, if you're interested in any of these five games, this weekend is the time to try them out. You can decide whether they're worth buying before the free access ends on September 14.
