Zombdroid Servants are servant droids turned into killers by a digital strain of the Thera Virus, introduced in in SAS: Zombie Assault 4.
Some Zombdroid Servants are known to be infected servants of the VIP (in the VIP mission) of SAS 4. All Servants have relatively high health and can do a large amount of damage with their swipes. Later on, when more and more Zombdroid Servants appear, Savage Zombdroid Servants may appear in the place of many regular Zombdroid Servants. They have several times more health than the regular Servant and their melee damage is much higher.
Like Zombdroid Soldiers, the Servants appear only in VIP and Power Out. Zombdroid Servants are considered weaker versions of Zombdroid Soldiers, rarer and deadlier droids, which have some resistances, more health and twin fully-automatic guns, enabling them to attack from afar.
- Zombdroids are apparently very physically strong, as they deal a moderate amount of damage, and their Soldier counterparts carry a minigun in each hand. They are also much more resistant to flinch when being shot.
