What did Marathon duos mode change?

Marathon adds an experimental duos queue, aiming to broaden early access playstyles

Bungie has started testing duos mode in its extraction shooter Marathon, framing it as an “experimental feature” rather than a permanent replacement for existing team formats. Multiple items in your story set indicate the duos test is time-limited and being rolled out in phases.

In practical terms, duos mode targets players who don’t want to run either solo or a full three-person team. Bungie’s own framing suggests it’s an attempt to see whether this smaller squad size works for Marathon’s extraction-loop structure—particularly its balance, objective timing, and the pressure of risk-versus-reward gameplay.

A key detail is that Bungie warned some of the experience may feel imperfect. The coverage explicitly notes “jank” as a known risk for the early experimental build, which typically implies unresolved edge cases such as:

• matchmaking behavior
• team coordination systems
• balancing for engagements designed for other party sizes

Additionally, the reporting references the duos rollout and mentions Perimeter as part of how the feature is being staged (“rolling out as an experimental feature” on that location in one excerpt).

Why it matters for the scene is that extraction shooters live or die by player-team dynamics. A duos queue changes who you can match with, how fights are fought, and how much coverage you can provide during escapes and rotations.

So the overall outcome from the provided stories is:

• Marathon is experimenting with duos instead of just solo/triads
• It’s not presented as fully polished yet
• The change is intended to expand options for how squads form

If you’re looking for the best signal before you queue, the “experimental” label and “some things will be a bit jank” warning strongly suggest you should expect rough edges—while still viewing it as Bungie testing a new baseline for future team-size support.
