Marathon has begun a duos-mode experiment, which will allow players to team up with a partner for a limited time. The experiment is a response to player requests, and may become a permanent feature if it is successful.

The introduction of duos mode is a significant development for Marathon, and one that is likely to be welcomed by players. The feature has the potential to enhance the gaming experience, and may help to attract new players to the game.

The success of the experiment will be closely monitored, and may have significant implications for the future of Marathon and the wider gaming industry.
