Bestiary

Every zombie type and dangerous wildlife you'll run into

Universal modifiers

Almost any zombie on this list can spawn with one of two overlays on top of its base type — recognize these on sight (full detail in Combat):

Feral — glowing orange eyes, more health, hits harder, sprints even in daylight.
Radiated — faint green glow, tougher, regenerates health over time.

Standard and special infected

Type	Behavior / threat	How to handle it
Regular Zombie	Slow, weak, the baseline enemy you'll see everywhere	Basic melee is fine; the danger is being swarmed by several at once
Crawler	Always moves on the ground; easy to miss in grass, rubble, or dark rooms	Watch your footing indoors and in tall grass — it ambushes rather than approaches openly
Burn Victim	Common in Burnt Forest; can set you on fire on contact	Fight at range if possible rather than trading melee hits
Spider Zombie	Moves on all fours, has a stunning web attack, faster at night	Don't get cornered — the stun leaves you exposed to follow-up hits
Screamer	Spawns in response to "Heat" from base activity (crafting, forges, gunfire); screams to summon a horde	Kill it fast before reinforcements arrive; keep base noise/heat spread out to reduce how often she shows up
Infected Police Officer (Cop)	Large health pool, ranged acid vomit, suicide-rushes at low health	Fight at range if you can; back away once it starts its death-rush animation
Demolisher	Heavily armored, has C4 wired to its torso, hits hard	Shoot the explosive on its chest to end the fight fast instead of trading blows
Wight (Feral Wight)	Taller, faster, stronger than most zombies; always feral; can be summoned by Screamers	Treat as a mini-boss — gives the most XP and best loot of the standard roster, but fight it prepared
Mutated Zombie	Ranged spitter, projectiles inflict irradiated status; found in the Wasteland	Close distance quickly or fight from cover — don't stand in the open at range

Wildlife

Animal	Notes
Wolves / Dire Wolves	Often travel in packs — treat a pack encounter like a small horde, not a single fight
Bears / Zombie Bears	High damage per hit; zombie bears are tougher and can be summoned by Screamers late-game
Vultures / Zombie Vultures	Attack from above and retreat after landing a hit; can break blocks; more common in Desert and Wasteland
Mountain Lions	Fast, aggressive, and can catch you off guard while looting rural areas

Note: Radiated variants of animals exist too (e.g. radiated Vultures can spit acid) — don't assume "it's just wildlife" means "it's not dangerous" once you're past the early game.
