Marathon Update v1.0.0.4 Patch Notes
Marathon update v1.0.0.4 alters loot economies, nerfs thermal scopes, and cuts UESC enemy health.
Update v1.0.0.4 for Marathon adjusts item spawn rates, thermal optic ranges, and enemy difficulty while introducing new contracts and stability fixes.
Item Economy and Loot Spawns
Perimeter features increased Med Cabinets and Munitions Crates. Free Sponsored Kits for MIDA, CyberAcme, and Arachne grant more starting ammo, and Overrun raises default ammo capacity by 2. UESC Grenadiers drop EMP grenades less often, and the LUX bundle increases from 1000+100 to 1000+120.
Weapon Balancing and Thermal Nerfs
Thermal scopes suffer reduced visual clarity and shorter maximum ranges. Pistols drop to 40 meters from 55, Rifles, LMGs, and SMGs drop to 60 meters from 65, Precision Rifles drop to 80 meters from 100, and Snipers drop to 100 meters from 180. Gunfire and explosion audio travel distances increase.
Runner and UESC Combat Adjustments
Most UESC enemy health drops by 10% to 15%, and UESC boss shield health decreases by 25%. Rook players benefit from fixed map position tracking, resolved backpack deletion upon exfil, increased CyAc reputation gains, and a WSTR shotgun that spawns as Compromised.
Contracts, Zones, and Stability
Default objective nav point distances increase from 10m to 20m alongside the NuCaloric and Traxus contracts and an adjusted UESC Commander encounter. The Outpost Broken Wing entrance is temporarily disabled for tuning. Dedicated server crashes, client errors, IME typing bugs, and black screen loading hangs are patched.
Why this patch matters
Update v1.0.0.4 dials in combat balance by trimming thermal scope utility and softening UESC enemy stats.
