Wondering where to look for specific faction zombies with the appropriate setting enabled? Look no further!

Loners & Renegades - Car Repair/Auto Shops, McCoy Logging Areas, Construction Sites
Bandits - Banks, Factories, High-end Hotels
Duty - Army bases
Freedom - Police stations
Clear Sky - Fire departments
Ecologists - Secret bases, medical buildings
Military - Army bases
Monolith - Secret bases
Mercenaries - High-end Hotels, Offices, Prisons
Sin - Shelters, survivalist areas
UNISG - Secret bases

Each faction's random/global spawn chances (that is, their chance to be encountered anywhere in the world, not just in their assigned locations) can be tuned in the menus, though even going as low as 0.0 won't completely disable spawns of that faction.

Map mods should automatically be compatible, assuming they have zombie spawn regions set correctly; if your map has an army base with the army zone set properly, then you should see zombies with Duty and Military outfits there more often!

In both cases, "better" equipment is rarer than lower tiers. You are much more likely to see zombified rookies than veterans wearing higher-tier armours, and SEVA suits in particular are some of the rarest. Zombies do not currently spawn with Exosuit or full Exoskeleton outfits.

If the weapon submodules are enabled, zombies also have a good chance to spawn with weapons equipped, though they will often not have ammo or even a loaded magazine, and definitely won't have spares of either. Equipment quality also varies with the base 'tier' of an outfit, with rookies tending towards basic rifles and shotguns, with only (formerly) experienced stalkers carrying automatic or precision weapons like assault and sniper rifles. SEVA wearers in particular tend towards long-range loadouts!

A zombified stalker can spawn with up to three potential weapons; a hunting/combat knife, a handgun, and a 'longarm' or 'primary' weapon such as a shotgun, SMG, or rifle of some kind. The exact weapons vary, pulling from a pool that depends on the weapon submodule enabled; with Gunfighter/Brita's especially, weapons are more factionalized, with Freedom and Monolith zombies having 'Western/NATO' weapons and Duty and Military having 'Warsaw Pact' weapons as examples.
