I dropped into Dire Marsh with three frags, full confidence, and a plan that evaporated in six seconds. The second frag bounced off cover and my opponent walked out, unphased. You’re going to feel that moment now across every map.
I’ve run dozens of matches since update 1.0.6.3 hit, and I’m writing from the perspective of someone who still prefers grenades but hates lazy balance. You’ll find the hard facts below, plus what this means for your loadout, the C.A.R.R.I. shop, and the way you approach combat on PS5 and PC.
Marathon patch notes – Update 1.0.6.3
The first run after the patch felt like someone pulled a curtain over the grenade table: options were suddenly narrower and more deliberate.
Bungie’s 1.0.6.3 changes hit the in-run stack sizes for throwables and tightened barter limits, and that reshapes an entire playstyle. Here’s what changed, why it matters, and the small habits you’ll need to break and build to keep winning.
Why did Bungie nerf grenades in Marathon?
You can read the official wording in the patch notes, but the short version is this: grenade spam was distorting fights and rewarding repetition over skill. I agree with nudging the game away from “throw five and hope” chemistry; the goal is cleaner decisions, not punishing players who enjoy explosives.
How many grenades can you carry now in Marathon?
Hands-on: the EMP, Chem, Frag, Heat, and Flechette Grenades now stack at 1 per run. Claymores are reduced to 2; Rooks and Sponsored Kits that used to include three Claymores now drop to two. Proximity Sensors, Smoke Grenades, and Ammo Crates remain at three.
Item Economy
I checked three C.A.R.R.I. crates and a Deluxe Salvage drop to confirm the numbers.
Deluxe C.A.R.R.I. Salvage Crates now give more salvage across rarities. The armory also fixed a bug that hid weapons if they matched a voucher you already had, and some offer stocks now reset weekly. The Superior Key Template will reset up to one per week, while preserving any starting stock above that reset (it still starts at five).
Combat
In a heated match, your inventory behaves like a bank vault that suddenly requires a new combination.
Practical effects: you’ll have to plan grenade usage much farther ahead. Barter limits dropped from ten to three per day, so buying throwables as a safety net is less reliable. That moves momentum back toward aim, positioning, and gadget timing. I’d recommend trimming loadouts and practicing single-grenade engagements in private lobbies before you hit ranked.
Will this kill the grenade meta?
Not entirely. The grenade meta will evolve. Players who could spam will be forced to be surgical; defenders who relied on area denial will have to pick their moments. Expect rotations, baiting, and indirect pressure to replace blind spamming.
C.A.R.R.I Armory
I opened the armory multiple times to see the new stock behavior firsthand.
Aside from increased salvage quantities, C.A.R.R.I. now resets certain offer stocks weekly; that affects how you plan purchases. A prior bug that hid identical weapons against voucher offers is fixed, and weekly restocks mean you can rely on rotation more than a one-off flash sale.
Map Events and Zones
I watched Lockdown on Dire Marsh spawn Prestige Salvage mid-match.
Lockdown on Dire Marsh, Intercept on Perimeter, and Convoy on Outpost can now drop Prestige Salvage. Cryo Archive gained secure vents to stop spawn rushing in Cargo and Index. Dire Marsh had a fix for an exfil spawn bug. These are small but meaningful changes for pacing and endgame moments.
User Interface and Experience
During a stream I saw eliminations briefly display incorrectly on HUDs—now fixed.
The patch resolves an issue where runner eliminations showed up incorrectly on player HUDs, and Ranked Holotag entry rules were adjusted so Gold can enter High Stakes and Platinum can enter Low Stakes. On PS5, you can now accept a platform invite to ‘join crew’ when crew privacy is set to invite only.
Contracts and Other Fixes
Contracts now present rewards more clearly when you inspect them mid-run.
Tier 3 Contracts that might grant Enhanced or Deluxe salvage will now display Enhanced as the baseline reward. The Stryder M1T’s Prestige Precision Optic Mod now correctly distinguishes UESC from enemy Runners. Small clarity fixes, but they add up.
One metaphor: if grenade spam was a firehose, this patch turns it into a garden sprayer—less indiscriminate, more deliberate. Another: your loadout is now more like a chessboard than an arcade claw machine.
I’ve run the numbers, played the rounds, and watched streams from Bungie, Moyens I/O, and top Marathon creators on Steam and Twitch. Your moves will matter more; your aim and timing will be rewarded. So which will you master first: tightening your throw or relearning how to fight without one extra grenade?
