The XS1 Vulcan is a 600-point scorestreak. Once acquired, players will take out their tablet and take control of a satellite. It requires 600 score to acquire. Upon pressing the fire button, a charge meter can be seen powering on the top of the HUD. After a certain amount of charge, there will be an option to instantly charge the laser titled "rapid charge". Upon complete charge, a laser beam will fire down from the sky, slowing the users movement speed and nearly instantly killing any enemies within the beam, but it is possible to escape the beam before it manages to get a second hit on the player. The base Vulcan lasts for a few seconds, but time can be extended with the Extra Time module. The Vulcan satellite is not visible and cannot be attacked directly. However, a System Hack with the Disable Streaks module can destroy a Vulcan, earning the offender the Icarus medal.
The Extra Burst module allows another laser burst to be fired from the same satellite. This module can be taken twice, for a total of three separate laser bursts.
It is somewhat effective against enemy A.S.T.s, but there are better scorestreaks to use against them. It is overall mostly effective against enemy infantry. It leaves the player vulnerable on the ground since it is controlled, so the player should be cautious about where they choose to stay while controlling it, as enemies could easily assault the player and down/kill them while the player is using the Vulcan.
