Survival protocol: auto-fire, reload windows, wave pressure, loot rolls, permanent scars.
Each wave escalates: more infected, faster pathing, tighter spawns. Standing still is a death sentence.
Your gun fires automatically. Your job is to aim with movement, time reloads, and never let them close the ring.
Roll gear, stack perks, build synergies. Small choices compound. The meta is movement + DPS + survivability.
