- For quest-only bosses, see quest boss.
Many of the "Special" type infected types also have a boss form, introduced in beta v0.52 and beta v0.54 , which looks like a "Supercharged" version except without the floating skulls. These bosses have deadly attacks and an extremely large amount of HP.
Each boss will only drop good loot (including experience and reputation) once a week. If you kill them more often, you will get poor loot. But for most players, you don't get any loot after you kill a specific boss without it resetting. Boss kill counts reset sometime on Thursday 12am UTC, after which point you can gain good loot from each of them again.
Visit the page for each boss for potential spawn locations and strategies. It appears bosses can appear in any spawn area that spawns infecteds with a legendary infected level[Confirm] (which includes secret passages as well as other locations around the map).
