The game is set in the near future and follows a team of four misfit agents collectively known as Overstrike 9, whose mission is to stop the evil Raven Corporation from gaining an alien substance called Fuse. Using Fuse powered weapons and tech gadgets and lethal teamwork to gain the energy. The members of Overstrike 9 are Dalton Brooks (voiced by
Brian Bloom), a reformed and sarcastic mercenary, equipped with a Mag Shield, which is an energy shield, Naya Deveraux (voiced by
Jennifer Hale), worked for Raven with her dad, she is equipped with a cloak device and has a gun that creates tiny black holes called the Warp Rifle, Isabelle "Izzy" Sinclair (voiced by
Ali Hillis), a gifted, but rebellious young scientist, equipped with a crystallization gun called the Shattergun, and Jacob Kimble (voiced by
Khary Payton), a decorated detective with a bit of a temper, equipped with a fire crossbow called the Arcshot. Their government handler is Lyndon Burgess, codenamed Oculus (voiced by
David Kaye). The antagonists include Dalton's ex-lover and boss, Meilin Mao (voiced by
Gwendoline Yeo), Naya's estranged father working for Raven, Luther Deveraux (voiced by
JB Blanc), Ivan Sovlenko (voiced by
Steve Blum), who purposely injects himself with Fuse to grant himself superhuman abilities and Senator William Fable (voiced by
David B. Mitchell), who plans to use Fuse to make his weaponry more powerful. A top secret government weapons lab, called Hyperion Base, had mysteriously went quiet some time after Senator William Fable arrived. In response to this, Lyndon Burgess sends in his black ops team, Overstrike 9, to investigate. Once inside, they learn of Fuse, an alien substance that radically bonds with anything it comes into contact with, used in development of advanced weapons. At the same time, Raven, a paramilitary corporation, breaks in. Overstrike 9 manages to reach the main Fuse lab. Though Dalton orders it destroyed, Izzy "accidentally" opens the main Fuse vault at the same time Raven captures the lab. Dalton's former lover and boss, Meilin Mao, appears, holding Fable hostage. Dalton threatened to kill Fable, suspecting that he allowed Raven into the base but his team reminds him that they are outnumbered, so they surrender. Overstrike 9 is brought to Raven's underwater Triton Base, where it is revealed that Dalton's suspicions were correct, as Fable was in league with Raven. At the same time, Naya is reunited with her estranged father, Luther, who seeks to aid their escape. Overstrike 9 then goes to the base's Fuse core and prepare to detonate it but first had to deal with Ivan Sovlenko, who purposely injects himself with Fuse to create illusions but they defeat him. Overstrike 9 then escapes the destruction of the base. The team is later sent to Sheng Island, where Meilin was planning to launch a corrupted Fuse rocket at a populated area as a demonstration for interested buyers. They were able to lock the missile in place and Dalton kills Meilin, narrowly escaping as the corrupted Fuse ignites, destroying all life on the island. Overstrike 9 is next sent to Karakoram in search of Luther and Fable. But at the same time, Fable betrays Raven, revealing to be in league with a mysterious organization only known as "the Order". He coerced half of Raven to defect and steal the corrupted Fuse. Overstrike 9 is unable to attempt pursuit. For their failure, the client that hired the team rescinded their contract. However, Naya convinces the team that her father might be able to help them locate the Fuse and reveals that she had located his safe house in
Jodhpur. With Burgess' aid, Overstrike 9 storms Luther's compound at the same time Fable's loyalists assault it. Fighting their way through both way through both Raven factions, Overstrike 9 manages to locate Luther and enlist his aid against Fable. Overstrike 9 goes into space, where Fable was deploying satellites to fire Fuse-powered missiles to create an extinction event and force the world into ending conflict, framing Raven as a scapegoat. As a demonstration, Fable wipes out
Munich. Overstrike 9 manages to prevent Fable from firing anymore by launched AI-controlled shuttles into destroying the satellites. They then arrive at the last vault of corrupted Fuse. They managed to destroy it at the same time Fable engages them in a powered exoskeleton. After a vigorous battle, Overstrike 9 is able to vaporize Fable before narrowly escaping the space station's destruction. Then suddenly, their shuttle collides with debris. Burgess and his client presume Overstrike 9 dead and agree to cover up the destruction of Munich to have been perpetrated by Raven fanatics. Burgess also learns from the client that Fable's faction was known as the Order of Grigori, who may be searching for other stockpiles of Fuse. Up in space, it is revealed that Overstrike 9 had survived and are merely unconscious. Dalton then opens his eyes, revealing that they are glowing, hinting that he, and presumably the rest of his team, have bonded with the Fuse. ==Development==
