Marathon Update 1.0.6.3 Restructures Grenade Stacks and Loot Economy

Marathon Update 1.0.6.3 alters in-run grenade stack sizes, adjusts C.A.R.R.I. Armory stocks, and introduces Prestige Salvage to map events.

Bungie has deployed Marathon Update 1.0.6.3, bringing substantial adjustments to item economies, equipment carry limits, and armory rewards. The update rebalances combat utility by lowering stack sizes for common throwables and revamping how players access C.A.R.R.I. weapons and salvage.

Grenade and Ammo Rebalancing

In-run stack sizes for multiple grenades have been reduced. EMP, Chem, Frag, Heat, and Flechette grenades now stack up to a maximum of 1. Claymores drop to a stack size of 2, meaning Rooks and Sponsored Kits that previously granted 3 Claymores will now provide 2 instead. Proximity sensors, smoke grenades, and ammo crates remain unchanged at stack sizes of 3, though ammo crate barter limits have been lowered from 10 down to 3 per day. Meanwhile, the Stryder M1T Prestige Precision Optic Mod now clearly distinguishes between UESC and enemy Runners.

Armory and Loot Economy Adjustments

Map events including Lockdown on Dire Marsh, Intercept on Perimeter, and Convoy on Outpost can now drop Prestige Salvage as part of their loot rewards. Deluxe C.A.R.R.I. Salvage Crates drop increased quantities of salvage across all rarities. The armory also resolves an issue where the Hurting Hands V4 could be claimed for free multiple times, and fixes a bug where C.A.R.R.I. weapons failed to appear if they matched an active voucher offer. Non-refreshing C.A.R.R.I. offers now reset weekly, with the Superior Key Template's stock restricted to a reset limit of 1 while preserving any starting stock of 5 or remaining stock above the limit.

Contracts, Zones, and Matchmaking

Tier 3 Contracts offering Enhanced or Deluxe salvage now consistently display Enhanced salvage as their baseline reward. In the Cryo Archive zone, secure vents were added to Cargo and Index to prevent spawn rushing, while an issue preventing the final exfiltration from spawning on Dire Marsh was resolved. Ranked Holotag entry requirements were shifted: Gold Holotags can now enter High Stakes, and Platinum Holotags can enter Low Stakes. On PS5, players can now successfully join crews via platform invites even if crew privacy is set to 'invite only' in-game, and incorrect runner eliminations on the HUD have been fixed.

Why this patch matters

Update 1.0.6.3 forces players to be much more deliberate with tactical throwables by slashing stack sizes, while smoothing out armory economy loops and ranked entry rules.
