Shuriken are fast, maneuverable, computer-guided strike craft. They may deploy to engage enemy space craft or ground units. The Plasma Charges of a flight of Shuriken may threaten capital ships, and the psi-blades lining the outer rims of the Shuriken that give them their name are strong enough to cut through reinforced armor plating.
Harbingers manufacture Shuriken. When deployed the strike craft attack and retreat rapidly to the Harbinger for repairs and rearmament.
Shuriken may be upgraded to possess the permanent cloaking technology of Observers, further increasing their lethality.
