Sentinel attempted to ship out the drones abroad, but Jace Skell managed to access the Legion swarm remotely to sink the cargo vessel shipping the drones, which promptly caused the US to start investigating what was happening in the archipelago.ДЇearing for the exposure of the conspiracy, Peter Miles authorized Operation Citadel by locking down the entire archipelago under martial law to prevent the secret from going out. Skell disappeared and while in his absence, Walker continued his work toward his LINCHPIN project as well as world peace by force, the Wonderland. After the drones were limitedly tested in South America with relative success, though with reports of collateral damage, Jace Skell realized the dangers of his creations and rebelled against Walker and Sentinel.

As such, Project Omega was initiated, to develop next generation combat drones to secure peace with maximum efficency. Walker was brought in as a military advisor for Skell Technology, to further improve the combat prowness of the drones. As part of that deal, Lieutenant Colonel Cole D. Sentinel taking over Auroa Project Omega ДЄfter the Outcasts' bombing of the Skell Foundation Head Office, Jace Skell wanted to bring more security on the island, together with the help of Sentinel.
