After over two years, London Conspiracy announced its return to Halo on February 13, 2017, again acquiring the Team Vibe roster. The roster this time around consisted of (again) Septic, now going by "SeptiQ", alongside Ryan "Batchford" Batchelor, Andrew "Ramirez" Corrigan, Casey "Lunny" Lunn and coach Kyle "Turk" Wall. The new London Conspiracy roster's first task was qualifying for Halo World Championship 2017, which required a top 2 finish at Gfinity London 2017. They started off on the right foot with a 3-0 victory over Epsilon eSports, but were decimated in the Semifinals by FAB Games eSports. In Losers Round 4, they were swept by Supremacy, resulting in a top 6 finish. On February 20, Batchford announced his free agency. London Conspiracy competed in the Last Chance Qualifier with Christopher "Qristola" O'Keeffe acting as the fourth member of the roster. They won the tournament and qualified for Worlds, and Qristola was officially confirmed as Batchford's replacement shortly after. At Worlds, London Conspiracy were placed in a pool with Team Liquid and Luminosity Gaming. Both of the North American powerhouses made short work of London Conspiracy, and they were sent to Losers Round 1 after back to back losses. They would fare no better in the bracket, losing 4-1 to TMMT Crowd Pleasers and going home with a top 12 finish.
Following Worlds, London Conspiracy parted ways with its roster, which began using the name Invictus.
