Deep beneath Warsaw, a team of specialized operatives gathered in the sewers to plan their assault on the ominous Revenant Tower. While recovering from injuries using a short rest mechanic, they discussed various infiltration options as their newest member, Hunter Hawk Williamson, joined their ranks. Hawk was an amnesiac marksman recovered from a Russian void bridge incident, deployed by Project Genesis under Colonel Gerald Cross and Dr. Walter Davenport's supervision to assist the team.
The infiltration began with Gaston Dubois, transforming into his signature green gaseous form to enter the tower's ventilation system while the team carried his empty suit. From his sniper position overlooking the tower, Hawk created a distraction by reanimating a fallen soldier loaded with explosives. The resulting blast created an entry point, though it drew out eight remnant drones. Ellie Mae Harper quickly dispatched two with lightning strikes while Hawk's precision shots eliminated two more.
Inside the tower, Gaston reached the security room and successfully deactivated the Tesla tower relays, disrupting the zombie control signals. After reuniting with his suit, he planted an unstable mine beneath the security room. The team discovered a key to access the restricted upper floors, revealing three blacked out levels and mysterious force field barriers. They encountered Takeshi, who struggled against the tower's corrupting energy.
Patrick Danielson scouted ahead and located a reinforced window leading to the power source - a massive generator room guarded by a heavily armored sentinel. He planted explosive charges on the window and tested the energy barrier using rainwater. Meanwhile, the team accessed the ornate throne room on floor 65, where they confronted the tower's cybernetic commander, who possessed a massive pneumatic claw arm and void-energy saber.
The confrontation escalated as the commander released revenant soldiers from containment chambers. Though Hawk briefly controlled some enemy forces, the commander demonstrated devastating combat abilities. The battle turned dire when Gaston suffered critical damage to his containment suit, threatening his very existence as his gaseous form began to dissipate. Throughout the facility, they encountered various specialized equipment including Hawk's Tech Burst Pistols, Gaston's unique gas knife, and the mysterious void energy weapons that seemed to connect to the tower's dark purpose.
