With Bungie officially leaving Destiny 2 behind next month, it's full steam ahead on Marathon, which is now days away from entering its Season 2: Nightfall. Ahead of the season kicking off on June 2, 2026, developer Bungie revealed a developer insights video and accompanying blog post that dives into some of the biggest changes in Season 2, like a reworked progression system, the new Sentinel Runner Shell, the Night Marsh map, and more.

You can check out the video below for the highlights of what's changing in Season 2, though if you want the nitty-gritty details short of what you'd expect in patch notes, you'll find those in the blog post. Here, we'll go through a mix of both.

As someone with 80+ hours in Marathon, the most significant change is clearly the reworked progression system and the changes to how mods and implants are communicated to players. Starting with Season 2, the pros and cons of different implants will be more clearly communicated to players as they will be "defined by their perk first and have fixed stats, with the name of each implant reflecting its perk."

Being unable to quickly tell certain implants and mods apart while looting or while just trying to prepare your loadout for another run has been a major source of friction for players, so it's good to see this ironed out with a new approach for Season 2.

As for the new progression system, which Bungie is calling The Cradle, its introduction will seemingly make progressing through Marathon feel entirely different from how it did for the whole of Season 1. You'll now be able to unlock skill points through Energy and be able to spend that Energy across six different stats that you can reset and re-spend at any point throughout the season.

You can spend all your points on strength at the start of the season, and if you find that's not working for you at any point, swap everything out and spend it all in endurance, support or dexterity. The key layer to all of this is that the main way you'll progress all of these stats is by converting your loot, including weapons, implants, and other valuable items in to Energy.

It's a massive improvement over simply being able to sell loot you didn't want or need for credits, and makes every run that much more significant, because even when you come back with an implant, weapon, or mod you already had, spending it on Energy lets you have a more permanent form of progression instead of it sitting in your Vault and potentially being lost on a failed run.

Of course, you'll still want to have a trove of backup weapons for runs, but this change, and Bungie simply increasing the maximum Vault size, are huge improvements to systems management. Also, keeping with progression changes, Contracts have also been given a revamp to make them more accessible for players to complete, as Priority Contracts will no longer be gated by Faction Reputation levels, and we'll see less annoying contracts, like ones that demand you cross a map multiple times to complete different objectives in a single run to be successful.

Other highlights are, of course, the aforementioned new Sentinel Runner Shell, which is designed to prevent teams from being so quick to close the gap between them and an enemy team with abilities like the Snare Mine and be another layer of defence from teams launching a swarm of grenades with its Defender System ability. Its Prey Tracker ability also helps it play a bit of offense, activating a radar to let you see nearby moving targets.

The new weapons this season are the KKV-9SD SMG and the D54 Battle Pistol, both seemingly solid additions for close-range combat against Runners and UESC units. There was also another quick mention of the experimental PvE queues to come in the blog post, though more on those will be revealed closer to when they actually launch in Season 2.

Overall, this all seems like it'll be a strong refresh for Marathon, potentially giving it the resurgence the game needs now that its Bungie's core focus going forward. We'll see if Season 2 can give the game the meaningful boost that was missing from Season 1.
