Blink packs

Blink pack are small antenna like devices that allow some high-end Scrin unit to teleport anywhere on the battlefield. Only a few of these units has been witnessed using this advance technology: Shock Trooper (Scrin), Prodigy and upgraded Eradicator Hexapod. It is also worthy to note that Traveler-59 Shock Troopers seem to come "pre-equip" with those devices, while regular Scrin fores and Reaper-17 must research it at a nerve center.
