Discharge tar-like mucus slowing its prey.

Tar Mutalist MOAs are Infested Corpus MOAs that launch globs of mucus to create puddles of thick tar, which damage and slow enemies to a crawl.


  • Launches a salvo of four projectiles, each one creating a puddle of acidic tar that deals damage per second and slows players that linger on it.
    • Slow debuff affects movement speed.
    • Tar puddles will dissolve after 10 seconds or when destroyed by ranged and melee weapons.
    • The puddles deal Corrosive b Corrosive damage, which is extra effective against the player's Ferrite armor.
  • Can leap away to put distance between themselves and their enemies. They can also leap high to avoid taking damage, sometimes giving the illusion of them disappearing.
  • Can perform a ground stomp similar to Shockwave MOA, stunning and knocking back players touched by the shockwave.
  • As with standard MOAs, shooting at the Tar Mutalist MOA's "chest" counts as a headshot, dealing 2x damage, while shooting the fanny pack (manifested as a tail-like appendage) on its back deals 3x damage.
  • Has a higher movement speed than other Infested units.
  • Can be Disarmed using Loki's Radial Disarm, which does not damage them but disables their spit and stomp attacks, leaving kicks as their only means of damaging players
  • Many frame powers target their fanny pack, dealing 3x damage.


  • The Tar Mutalist MOA was first introduced in Devstream 35, alongside its Swarm counterpart. It was initially referred to as the Slow Bomb MOA.
    • Curiously the Slow Bomb MOA moniker was referring to the design that would later be used for the Swarm Mutalist MOA and vice versa.
  • For a long time after they were released, puddles of bile would damage and slow players while under MindControl130xDark Mind Control or when produced by Shadows.
