Key changes
- New Pottsville Scenario #2: Responders spawn on Downtown rooftops, align antennas under a timer, locate and burn bodies to prevent NPV-26 outbreaks, then reach the outskirts for extraction.
- Weapon attachments system added: Muzzle Brakes (rifle recoil), Compensators (pistol/rifle recoil + hip-fire spread), Laser Sights in Micro and Large variants (hip-fire spread), and Shotgun Chokes (medium-range effectiveness).
- Normal difficulty gains a final respawn window at the start of the extraction sequence, completing the respawn coverage that 1.0.4 added only to Survival.
- Nightmare Threat Level 10 horde composition adjusted: Walkers shift from 60% Normal / 40% Prime to 39% Normal / 59% Prime; Runners shift from 10% Normal / 5% Prime to 7% Normal / 10% Prime.
