Wave Escalation Timeline
Prepare your defensive line. Each round intensifies the breach pressure with evolving mutant biology, devastating special abilities, and endless midnight siege conditions.
Shufflers & Walkers
Fragile, slow-moving infected scattered in minor clusters. Ideal for learning movement routines, securing baseline currency, and fortifying initial perimeter barricades.
Feral Runners
Agile, rapid sprinters targeting vulnerable flanks in coordinated packs. Demands immediate shotgun upgrades, secondary wall reinforcements, and tactical tripwire setup.
Armored Hulks
Reinforced plate-wearing infected resistant to standard small-arms fire. Concentrated heavy rifle fire, automated turrets, and high-impact explosives are required.
Wall Breakers & Exploders
Volatile bio-engineered carriers designed to breach reinforced concrete walls with suicide detonations and smash foundational barricades.
Mutant Stalkers & Leapers
Acrobatic predators capable of vaulting primary blast gates and attacking defensive platforms from elevated angles with acid projectile barrages.
Colossal Siege Behemoths
Massive multi-story titan organisms accompanied by endless hordes and permanent midnight weather. Requires coordinated survivor AI squads and max-tier energy barricades.
Mutant Threat Database
Tactical dossiers on hostile mutant strains encountered during outpost defense. Review attack behaviors, vulnerability specs, and optimal weapon counters.
Wave Escalation
Every 10 rounds a dominant boss strain breaches the perimeter. Boss encounters feature massive hit point reserves and wall-crushing strike sweeps.
