Dark Swarm worked similarly to the defiler's version, creating a smokescreen for units to hide under, protecting them from ranged attacks.[7][8][9][10]
Dark Swarm protected units from a ghost's Snipe attack as well.[11]
A roach's attacks were unaffected by Dark Swarm.[12]
The infestor used to have these abilities as well.
The infestor targets a single unit or structure (even flying ones), draining it of 4 hit points per second and gaining half that back in energy. The ability is channeled and can be autocast.[19]

↑ 17.017.117.2Already mentioned by a few, but M&Ms are very susceptible to any AoE type abilities/attacks. For example, they fall quickly to Banelings (if they get close enough, usually using burrow), Psi Storm, Colossi, Siege Tanks, and Disease (does 100 damage to units in an area but will not kill the unit - replacing fungal infestation). 2009-04-28.
