The Cradle system finally fixes Marathon's stat progression
Season 1 of Marathon tied your stat upgrades to Faction standing, which meant a bad run of wipes could set you back hours of progress. Season 2 scrapped that entirely. The Cradle is a permanent upgrade tree that lives in your Shells menu, survives seasonal resets at the node level, and applies every point you invest across all your Runner Shells at once. Your Energy is also fully refundable, so a build you hate today costs you nothing to undo tomorrow.
Cradle upgrade tree overview
To access it, open your Shells menu and select "Access Cradle." Six stat categories sit in front of you, each with base stat bumps and passive perks gated behind Energy thresholds. You need to hit Cradle Level 84 to max every tree, but the perks that matter most come well before that ceiling.
How do you farm Cradle Energy fast?
Every 1,000 XP you earn raises your Cradle Level by one, and each level rewards you with Energy to spend on nodes. Two methods feed XP into that pool reliably.
The first is Contracts. Season 2 removed the Faction restriction, so every completed Contract regardless of which Faction assigned it dumps raw XP directly into your Cradle progression. If you want to grind Contracts without getting ambushed, adjusting your matchmaking settings before dropping in is worth the extra thirty seconds.
The second method is the Matter Converter. Open your Vault, select any gear you extracted that you no longer need, and hit "Convert Matter." The item disappears and XP appears instantly. Season 2 also added a batch selection feature to the Vault specifically to make this process faster, so clearing out a cluttered stash after a good run is now a reasonable way to push toward your next Cradle Level without queuing into another match.
Every Cradle upgrade tree explained
The six trees cover different playstyle needs. Base stats increase as you invest points, and each tree has three passive perks locked behind specific Energy costs.
Endurance tree node selection
What are the best early Cradle upgrades to unlock?
Spread your first points evenly and you will end up with a Runner who is mediocre at everything. Pick a lane instead.
Endurance is the strongest opening investment. Heat Capacity determines how long you can sprint, and sprinting is how you win positional fights, reach loot before another team, and escape situations that would otherwise cost you your gear. Quick Vent costs only 3 Energy and cuts the delay before heat starts recovering after you push your stamina hard. That perk alone changes how aggressive you can play in the opening minutes of a run.
Once the Endurance foundation is in place, move straight into Dexterity. The Agility bump feels good immediately, but the Loot Speed increase is what actually matters. Standing still while opening containers is one of the most dangerous things you can do in an extraction shooter game, and shaving time off that animation reduces your exposure window in a way that compounds across every single run.
If you run a heavily armored Shell, the Resistance tree becomes a strong third priority. TCIV Resist at 8 Energy reduces incoming damage from Ticks, lightning, and Heat Cascades, which are exactly the hazards that punish armored builds trying to hold positions in dangerous zones.
How does the Cradle interact with your Runner Shell?
Every point you invest applies to all Shells simultaneously, which means your Cradle build needs to work for your entire roster rather than just one character. That said, certain perks pair naturally with specific playstyles.
The Recharge tree's Lethal AMP perk rewards aggressive PvP players who can consistently down and finish Runners. Head Start and Primed give you partial tactical and prime charges at the start of every run, which pairs well with Shells that want to use their abilities early in a match rather than farming charges through the mid-game.
Support perks are worth considering for teams that run together consistently. Optimal Support at 14 Energy means revived teammates come back with significantly more health, which can flip a fight that looked lost. Factory Reset, the 10 Energy perk, restores your own health when you revive a crewmate, making aggressive revives less punishing.

Resistance tree TCIV Resist perk
Building around Season 2's new additions
Season 2 introduced the Sentinel Runner Shell alongside the Cradle, and its trap-focused kit creates some specific Cradle pairings worth considering. Sentinel's Snare Mine and Defender System reward players who hold positions and control space rather than pushing constantly, which makes the Resistance tree's TCIV Resist and Scab Factory perks genuinely useful for surviving the blowback when enemies push your setup.
The new Night Marsh map also changes how Endurance performs. Darkness forces slower, more deliberate movement, but the map features a smaller player count than standard Dire Marsh. Heat management still matters for repositioning between objectives, but the reduced Runner density means you have slightly more breathing room to recover between engagements.
For everything else Season 2 changed, including the new KKV-9SD SMG, the D54 Battle Pistol, the reworked Implant system, and the full Night Marsh map details, the Marathon Season 2 complete breakdown covers all of it in one place.
