The swarm

'The Swarm' is a Scrin support power, enabled by construction of the Nerve Center, that allows them to teleport a number of Buzzer swarms to any visible location. This is, naturally, very bad news for any human infantry in the vicinity. As well as anti-infantry defence or offence in a pinch, this ability is useful to the Scrin for scouting purposes, as well as occasionally just creating a nuisance. It does, however, cost Tiberium to deploy each time.
