Overwatch 2 developer Blizzard has released a big new update for PS5, PS4, Xbox Series X|S, Xbox One, PC and Nintendo Switch.

The new Overwatch 2 update adds the 6v6 Experiment mode while also making a number of balance changes.

According to developer Blizzard, the 6v6 Experiment mode will be playable in the Unranked Menu from December 17 until January 6.

Map selection and gameplay is based on the Quick Play ruleset, with teams comprised of two Tank Heroes, two Damage Heroes, and two Support Heroes.

Blizzard describes it as a return to the game's roots: "Revisit the roots of Overwatch with the 6v6 Role Queue experiment, bringing back the structured 2-2-2 team composition for a limited time.

"This mode combines the thrill of the original six-player team dynamic with the strategic depth of Overwatch 2’s updated heroes and abilities.

"Dive in to experience a new balance of strategy, adaptability, and pure team synergy—showcasing how modern Overwatch gameplay thrives in a classic format."

The mode makes its debut just days before the release of this year's Winter Wonderland event.

Winter Wonderland comes with its own set of rewards, as well as limited time game modes like Mei's Snowball Offensive and Yeti Hunt.

In the meantime, you can check out the patch notes for the December 17 update below...
