Zombies (or known as Operations in ShooterofIO 1: Modern Ops (2023)) is a cooperative game mode known for being included in the ShooterofIO series most famously developed by Air Studios.
Zombies first appeared in ShooterofIO: Dark Warfare (2024). In this version, the Dark Aether Saga storyline began.
The mode is known for its repetiitve fast-paced action that involves players starting with a pistol (or a loadout weapon at a low rarity) and becoming more powerful by surviving endless waves of the undead. As the match progresses, the enemies become stronger, whilst in some older games, weapons become weaker.
Gameplay
ShooterofIO: Dark Warfare (2024)
Dark Warfare features the first iteration of the cooperative round-based mode called Zombies. In the mode, players must survive against endless waves of the undead whilst earning currencies to buy Perk-a-Colas, new areas, and other upgrades. The Perks Quick Revive, Juggernog, Stamin-Up, and Speed Cola return from ShooterofIO 1: Modern Ops (2023) with two new perks Deadshot Daiquiri and Death Perception being introduced. The mode features a out of match system—"Augments"—Augments allow players to add additional abilities to their ammo mods, perks, and weapons. Players can obtain Augments from collecting the in-game currency Plasma–by simply playing the game. During a game, whilst killing Zombies, players will find Power-Ups, such as Nuke, Max Ammo, Double Points, and Insta-Kill.
The mode launched with two maps "Undead Forest" and "Der Palace", both launch maps are set in the Dark Aether storyline. A third map "Turm der Toten" was released on December 16, 2024. A fourth map, titled "Origins", was released on January 24, 2025. A fifth map, titled "Der River", was released on April 3, 2025. A sixth map, titled "Boomtown Zombies", was released with Season 04. A seventh and final map for the first game, titled "Foldpoint", was released with Season 05.
Premise
Dark Aether Saga (2024)
In 1983, former archaeologist Noah Mad begins having vivid, lucid dreams of a woman named Samantha Voss, who claims to come from another thread of reality where the dead walk. She warns him of an imminent breach in the Everfall Rainforest — a rift she calls an Ecliptic Gate, leading into a realm known as the Dark Aether. Noah dismisses her warnings. Weeks later, he comes home to find his wife brutally murdered, her body surrounded by glowing spores that pulse like a heartbeat. Fueled by grief, he tracks Samantha down, who introduces him to rogue engineer Jessica Carver and disgraced military scientist William Peck. The group ventures deep into the cursed rainforest, now crawling with undead that phase in and out of reality. At its heart, they discover a crystalline monolith keeping the rift open. They destroy it, collapsing the jungle into a void — but their “victory” has consequences. The collapse echoes through the dimensional veil, tearing open twelve more gates across the world.
One of these new breaches manifests in the abandoned Weismark Palace in Washington State, a Cold War listening post turned spectral beacon. Battling glass-infused horrors, the team intercepts a transmission from Edward Richtofen, who claims to lead a covert agency called Requiem and possesses the means to end the Outbreak. Samantha rejects him outright, but Edward approaches Noah directly, convincing him the Palace is only the start of a dimensional merger. Noah joins him, fracturing the group. Samantha storms off east, while the Palace is destroyed — and Edward quietly pockets a pulsing artifact: an Ecliptic Core.
Samantha’s trail leads her to Turm der Toten (“Tower of the Dead”), a colossal Dark Aether tower jutting from the jungles of A Sầu Valley, Vietnam. Here, Colonel Lev Kravchenko and the Soviet-aligned Omega Group are siphoning Dark Aether energy to forge living weapons. Samantha infiltrates the tower but is captured and thrown into the Dark Aether itself. Edward, pressured by Noah, agrees to a rescue — recruiting Captain Sergei Ravenov, an Omega defector. Scaling the tower’s warped architecture, the team navigates gravity shifts and spectral storms to locate Omega’s Rift Engine. They reverse the machine’s polarity, tearing Samantha out of the Dark Aether in a blaze of violet light. Kravchenko is devoured by his own creations, but his second-in-command, Dr. Aleksandra Valentina, escapes with a shard of the Rift Engine.
Edward’s fixation deepens. He reveals his home reality, Dimension 63, where another Samantha died saving him. Believing he can resurrect her using this realm’s energy, he sends the reunited “Primal Crew” to Origins, a rift beneath the ruins of St. Petersburg. There they find the Prime Machine, a teleporter built by a prehuman civilization, guarded by Flesh Golems stitched from multiple timelines. Peck learns the machine needs Spectral Essence from every active gate. Noah, distrustful, tries to sabotage the harvest, but Samantha intervenes — revealing her powers are tied to the Dark Aether itself. She forcibly pulls the crew back to Requiem HQ, warning that destroying the gates too quickly could tear reality apart.
Two months later, the crew has disbanded. Noah leaves entirely — until New York erupts into chaos as an Outbreak spreads from the black, oil-like Der River, now twisting through Manhattan’s streets. Samantha, Peck, and Jessica are cornered when Valentina manifests, using the river as a conduit to merge worlds. She strips Samantha of her powers, declaring her intent to restore the Dark Aether to its “true form.” Noah returns, wielding a prototype bomb designed to neutralize the river’s flow. As skyscrapers collapse into the abyss, Edward arrives in Dark Aether–charged armor, scattering the undead. The river is purged, but Valentina escapes, now partially fused with the current. Tracking her leads Edward to Boomtown, a quarantined mining colony in New Zealand built atop an ancient meteor crater. The entire town shifts between decades with every siren blast, and undead miners wield spectral tools forged in another age. The Primal Crew fights to stabilize the area by shutting down smaller rifts — until Edward activates the Primal Gateway’s core, triggering the town’s collapse into the Dark Aether. Noah realizes Edward’s true goal: consolidating rift energy to reshape Dimension 63, not save this world. The crew barely escapes as Boomtown is consumed.
The final confrontation takes place in Foldpoint, the Dark Aether’s shifting nexus where past, present, and future bleed together. Requiem and the Primal Crew prepare to transport a nuclear warhead into the Gateway, hoping to collapse it. But Valentina opens dozens of secondary rifts, unleashing undead knights, mechanized revenants, and shadow-beasts older than Earth itself. Edward’s facade slips — he never intended to detonate the bomb. Noah offers to sacrifice himself, but Edward instead hurls a powerless Samantha into the Gateway. Her presence destabilizes the core, triggering a chain collapse that seals every rift worldwide and wipes out the undead. In the aftermath, Edward arrests the surviving Primal Crew, dismantles Requiem, and vanishes — vowing to “bring back some old friends” from the shards of the Foldpoint.
Development
Reception
The Zombies mode has recieved critical acclaim across the franchise and many sources say that Zombies peaked around the time of Dark Warfare III's release in 2015. This is because of the amount of maps that were added to the game during its life cycle and its gameplay being replayable in every aspect.
