The Skeleton is an enemy that is spawned by another type of zombie (which varies by game). They appear in SAS: Zombie Assault, SAS: Zombie Assault 2, SAS: Zombie Assault 2 Insane Asylum, and SAS: Zombie Assault 3.
In Zombie Assault, the Skeleton is spawned from a Wizard-like Skeleton. In Zombie Assault 2 and Insane Asylum, Skeletons appear after a zombie is killed if there is a Sprinter-like zombie in the wave. In Zombie Assault 3 and Tower Defense, the Skeleton is spawned from Devastators.
If left unchecked, Skeletons can be spawned in large numbers and overwhelm the player. Skeletons have very small health, though they can overwhelm with the mass amounts that can be produced. The best way to kill them is with grenades, or fast shooting weapons such as submachine guns and assault rifles.
- In the PC version of Zombie Assault 3, Skeletons appear to have regular hands. However, in the mobile version, their hands look more like scythes/long claws.
