### Sentinel Campaign

With multiple Sentinel installations and mainframes falling, the lead Sentinel AI activates the last remaining Mainframe and pushes back the Raak\-Zun invaders from within the underground facility while directing it's drones to observing and capturing a target specimen, revealed to be Ethan. Ethan is captured, wiped of his memories and transformed into a Symbiont, whom spearheads the counterattack on both Federal and Raak\-Zun forces, forcing Lex and the Chief Engineer to retreat to Earth, destroying their portal in the process. The Symbiont also activates a series of mainframes turned into detonators as a safety measure to destroy Elysium, identified as 'Trap 757'.

Afterwards, the Symbiont manages to establish contact with the stranded Sentinel drones on Earth allowing them to repair a portal on their side, allowing the Symbiont to travel to Earth in pursuit of a Parasite, revealed to be the aberration which had gripped Sauk and the Oracle, being discovered as an interplanetary being that travels between planets, leeching life and twisting lifeforms to perform it's bidding, essentially creating the Raak\-Zun. As the Symbiont fights through Federal and Raak\-Zun forces, the Federals under Lex and the Chief Engineer discover the Parasite bursting itself within the Federal Dome, attempting to escape Elysium, learning Trap 757 is an anti\-Parasite trap, and thus order their remaining forces to stand down, allowing the Sentinels to overcome the Raak\-Zun defenders and force the Parasite away and back to Elysium, which detonates in time to destroy it. With their function fulfilled, the Sentinels, including the Symbiont, deactivate themselves, becoming inert.

In the aftermath, as the Raak\-Zun remainders scatter and the Federals rebuild their dome, Lex investigates the deactivated Symbiont, determining it's been attempting to access a certain data file that the leading Sentinel AI constantly attempted to erase, but the Symbiont replicated itself non\-stop. As Lex access the file, discovering Ethan is the Symbiont, the safety protocols are broken. Because of this, the Symbiont awakes, it's breathing sound indicating Ethan had returned.


Can a Symbiont be used as a solution for interplanetary problems?
