Weapons: who won and who lost

Almost every assault rifle gained range or headshot damage. The Hyeon Burst’s Hyperburst Apex, which dominated launch, takes the big hit: its full-auto damage drops sharply. The VEL 46 loses some range, and the APOC-338 loses some headshot damage.

Multiplayer

  • The Argonaut killstreak is much tougher, with 1,200 health instead of 800.
  • Crossfire now has spawn protection. Its bullets hit a 25% smaller area for half the damage, and the camera shakes less.
  • Claymores trigger from 3.18 m instead of 2.29 m, across an 80° cone instead of 60°.
  • Text chat in Multiplayer and DMZ now defaults to Team/Squad.
  • Fixes include Binary Trigger reload canceling, Sprint Cancels ADS with variable-zoom optics, and Hardpoint captures not counting.

DMZ

  • X01: a new GRANIT Arms black site under Hajin.
  • Possum: the no-revive radius around the squad that killed you is 2.5 times larger, and the fallback timer goes from 4 to 5 minutes.
  • Supplied Drops: now covers Dynamic Ops crates, and the chance of an extra container doubles from 25% to 50%.
  • Weapon XP from killing AI with vehicles was reduced, and Crossfire does more damage to vehicles, especially tanks.
  • New event: Threat Briefing: Battle Tank.
