Spiders are an enemy type that appear in the Call of Duty: Black Ops III Zombies maps Dead Ops Arcade 2: Cyber's Avengening, Zetsubou No Shima and Revelations. They have the ability to shoot webs at the players, as well as be able to use their webs to cover up Perk-a-Cola, GobbleGum machines, and pathways, though the player can easily slash through them by holding the use button. They are also needed for the KT-4 weapon in the cage step, where the player needs to extract their venom. They will usually spawn on round 6. When the last spider is killed, it will drop a Max Ammo. Upon killing a spider, the player will receive 50 points, while non-lethal hits will not reward the player any points.
- If any zombie tries to walk through a spun web, it will get stuck and have webs swirling around it, similar to the effect of a Widow's Wine grenade, and the zombie will eventually die.
- The spiders will put webs only on perks found outside the bunker, except for those that spawned via airplane.
- In code, they are referred to as "Spiders from Mars".
