The Cradle is the progression system that arrived with Marathon's Season 2: Nightfall, replacing the way you leveled up and built your Runner throughout Season 1. Instead of selling unwanted loot for credits, you now feed weapons, implants, and other valuable items into the system to earn Energy, then spend that Energy across six stats to shape how your character performs on a run.
How the Cradle progression works in Marathon Season 2
The Cradle ties your character growth to a single currency called Energy. You earn Energy mainly by converting the loot you bring back from runs, and you spend it to unlock skill points. Those points raise six different stats, and your overall Cradle level climbs as you invest.
The most important rule is flexibility. You can pour everything into one stat at the start of the season, then completely reset and redistribute it later if that build is not working for you. There is no penalty for swapping. If strength is not paying off, you can move all of it into endurance, support, or dexterity and keep playing. This was detailed in Bungie's Season 2 blog post.
The six Cradle stats
Energy is spent across six stats, each tied to perks that change how your Runner plays. Maxing a stat unlocks its associated perk, which is shown directly in the stat's tooltip.
| Stat | Notes |
|---|---|
| Strength | Unlocks the Leech perk when maxed |
| Recharge | One of the six investable stats |
| Dexterity | Maxing unlocks WEAVEworms, which boosts agility and loot speed by +55 |
| Endurance | One of the six investable stats |
| Support | One of the six investable stats |
| Resistance | One of the six investable stats |
Convert loot into Energy
The Convert Matter screen is where loot becomes progression. You select the weapons, implants, mods, and other valuable items you want to spend, then confirm with Convert Items. Each item adds toward your Cradle level, which is shown as an XP value against the next threshold.
This matters most for duplicate gear. When you finish a run with an implant, weapon, or mod you already own, converting it gives you permanent stat progress instead of leaving it in storage where a failed run could cost you. You will still want a stock of backup weapons for future runs, but turning extra loot into Energy makes every successful extraction count toward your build.
Implant changes that pair with the Cradle
Alongside the new progression system, implants are now easier to read at a glance. Each implant is defined by its perk first and carries fixed stats, and its name reflects that perk. This makes it faster to tell implants and mods apart while you are looting or putting together a loadout, removing a common source of confusion from Season 1.
Contracts and accessibility tweaks
Contracts received a rework to fit the new flow. Priority Contracts are no longer locked behind Faction Reputation levels, so you can take them on sooner. Bungie also trimmed the more tedious objectives, such as contracts that forced you to cross a map several times in a single run to complete different goals.
How you know the Cradle is working
After converting items, your Cradle level and XP total update on the Convert Matter screen, and any newly available skill points can be spent on the stat screen. When you max a stat, its tooltip shows the perk as unlocked, like Leech under strength or WEAVEworms under dexterity. If you reset, the points return for you to redistribute, with no loss in progress.
Season 2: Nightfall is live, bringing the Cradle together with the Night Marsh addition to the map, the Sentinel Runner Shell, and new weapons in the KKV-9SD SMG and the D54 Battle Pistol. The progression overhaul is the centerpiece, turning the loot you pull from Tau Ceti IV into lasting character growth you can reshape at any point during the season.
