Marathon Release Date and Trailer Leaked Via Xbox Store

A new Marathon trailer briefly appeared on the Xbox Store, and it seems to confirm release date along with Deluxe Edition items for the game.

Over the past few weeks, interest in Bungie‘s upcoming extraction shooter, Marathon, has picked up again thanks to developer’s marketing push and a steady stream of new info.

That push started with Bungie’s Vision of Marathon ViDoc in December, which showed updated gameplay and highlighted changes since the closed alpha, including things like proximity chat and a solo queue. Then, earlier this month, Bungie followed up with a second long video focused on Runner Shells and how builds work through Cores and Implants.

The one thing Bungie still hadn’t pinned down publicly was the exact release date. The official work was that Marathon is coming sometime in March 2026.

Marathon Release Date and Trailer Leaked

Earlier today, that “sometime in March” window may have just gotten a lot more specific. A new Marathon trailer went live early on the Xbox Store and was quickly taken down, but not before people were able to grab it.

According to the leaked info from the trailer, Marathon is releasing on Thursday, March 5, 2026. The trailer itself runs for about 1 minute and 50 seconds. It shows an updated look at gameplay, environments, and characters, along with some dialogue lines from an unknown character.

You can watch the new trailer below.

The final moments of the trailer are where things get even more interesting. It ends with a screen showcasing the game’s Deluxe Edition and pre-order bonuses, giving players their first official look at what might be included at launch.

Marathon Deluxe Edition Items Leaked

Based on the screen shown at the end of the leaked trailer, the Deluxe Edition appears to include several cosmetic items. These listed items are:

• Destroyer skin
• Assassin skin
• Vandal skin
• Misriah 2442 Pump Shotgun skin
• Overrun AR skin

There’s also a text right above the “Pre-order Now” button that says: “Midnight Decay bundle and more,” suggesting there are additional items that were not fully shown or listed on screen.

Check out the leaked Deluxe Edition cosmetics below.

This confirms The Game Post’s report that revealed a large number of Runner skins, including some tagged internally as Deluxe Edition cosmetics. Apart from that, there was another leak that revealed the Destiny 2 side of Marathon-themed cosmetics. These included Armor sets and weapon ornaments. Check out our report on that here.

Bungie previously said that we’ll hear more about Marathon in January 2026. Going by that, an official announcement may be right around the corner, likely during this upcoming week.
