About ZEPHON


Humanity emerges, hesitantly, into ruination. Almost nothing is left of the world as we knew it—settlements, forests, seas, mountains—all have been blasted into unfamiliarity. Horribly mutated animals hunt in packs through deformed woodland. Decrepit military robots stumble unknowingly through the ruins, sensors and logic centres blown. Alien soldiers, once impossibly powerful, cower in the wrecks of their ships, praying to heedless gods for rescue.

Control the survivors of humanity in a near-future apocalypse of alien origin. Pick a path between the indifferent abominations of the Voice and the uncaring automata of ZEPHON, with city management, turn-based tactical combat, unholy research, diplomatic maneuvering, and branching narrative quests. Gather your allies and pick your actions wisely.

On the planet Earth, that was once a cradle of life, the extinction of humanity is at hand.

What will you do to survive?

BATTLE


Intense turn-based survival strategy in both single and multiplayer.

  • Command over 50 unique units in battle—each with its own graphics, voice overs, weapon systems and sets of traits and abilities.
  • Plan out optimal build orders amongst 3 asymmetric paths—Human, Voice and Cyber—or combine them in surprising ways.
  • Deploy tactical operations—interference protocols, otherworldly hymns of decay and even nuclear weapons—to gain an advantage.
  • Combat occurs on the main map—no switching modes and having to auto-resolve battles because they drag on too long.
  • Use distinctive leader abilities in fully-featured multiplayer—with or against your friends.

BUILD


Take your settlements from scrappy bases to sprawling metropolises as your faction expands its sphere of influence.

  • Find and grow your cities by constructing buildings on tiles—everything you build needs space.
  • Optimize an empire-wide economy with 11 tiered resources—allowing you to specialize cities by their placement.
  • Recognize each building by its appearance—3 architecture styles to accompany your chosen path.
  • Fortify key strategic points to prevent enemies from assailing your positions—sometimes defense is the best defense.

EXPLORE


Traverse the unfamiliarity of the destroyed Earth and unveil its deadly new secrets.

  • Discover dozens of terrain features and phenomena spread across 6 climates—flesh trees, microchip factories, traveling sandstorms, erupting volcanoes and much more.
  • Tune the generation of a new post-apocalyptic game world—cliffsides, ruins and deformed woodland occupied by violent wildlife and expanding NPCs acting out their own agendas.
  • Exterminate packs of mutated animals to collect caches full of rewards, capture outposts and expand your reach—one turn at a time.

RESEARCH


As mankind strives to catch up to the new masters of the Earth, you’ll make strange new discoveries that could be just what you need to survive.

  • Unlock over 150 technologies spread across 10 tiers—units, buildings, operations, weapons, abilities and passive bonuses.
  • Advance from post-apocalyptic survivalism—through a blend of magic and cyberpunk aesthetics—before achieving transhuman transcendence.
  • Observe each unit upgrade visualized on the model—outfit regular, large and titanic units with cruise missiles, tunneling nails, deflector shields, and much more.
  • Read exact modifier numbers in tooltips and the easy-to-browse in-game compendium—so you don’t have to scour the internet for information.

NEGOTIATE


Diplomatic negotiations are key to staving off defeat—but your opponents are watching your actions and reacting.

  • Roleplay with AI-controlled opponents through diplomatic encounters—each AI comes with their own likes and dislikes based on their character.
  • Establish peace, trading agreements and alliances—or use your influence to antagonize your friends towards each other.
  • Choose sides—ZEPHON, Acrin and Reaver non-player factions permeate the world and need to be contended with.

DECIDE


As the clash between ZEPHON and the Acrin continues, your choice of Leader and path will determine who survives in the wreckage of Earth.

  • Steer your empire through multistage, branching, unexpected events—nightmares, cries for help and economic crashes all have to be dealt with.
  • Dive into your chosen leader’s backstory through their unique quest chain—complete it to unlock a permanent reward.
  • Play a key part in determining if humanity, machines or horrors prevail—the clash between ZEPHON and Acrin continues across the planet.
  • Resolve the prophecy that has brought the Acrin to Earth to unlock new game modifiers—all of this has happened before, and it will all happen again.

“Open your eyes, singleton. You are not dreaming—you are the dream. The old world is dead, your old self is dead, so who are you now? We were the Meek, the Silent, and the Accomplice. Individually we were no one, together we are god itself. Woo us, fear us, worship us… these are all acceptable answers to the riddle of what you can do for us.”
— Furtive Tribunal

How much does ZEPHON for PC cost right now?

ZEPHON for PC starts at €6.71 at Difmark, 83% under the €39.99 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €39.99 at Steam.

That €6.71 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.

With 12 offers across 8 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.

Which format should you buy?

The cheapest route is a shared account at €6.71 at Difmark: you get into an account that already owns the game, but it never becomes yours. A key for your own Steam account starts at €39.99 at Steam, €33.28 more, and that is the sensible option.

The 7 Steam Gift offers start at €34.37, pricier and more prone to issues.

Can you activate it in your region?

11 of the 12 offers work on US — the Global ones plus the ones issued for your own region.

Why is one listing so expensive?

One listing is worth ignoring: the Steam gift that Difmark Digital Keys has at €52.32 is more than 7 times the cheapest offer and is not what this game costs. The number to work from is €6.71 at Difmark.

So, which ZEPHON deal should you buy?

There is no third-party key on offer today, so the choice is between the shared account at €6.71 at Difmark — cheap, but the game never becomes yours — and paying the official €39.99 for a key on your own account. Either is defensible; just know which one you are picking.

Information about ZEPHON for PC


ZEPHON sets out a post-apocalyptic world in which humanity is barely surviving on a planet Earth devastated by an alien apocalypse. What was once a familiar world is now a hostile landscape, filled with mutated creatures, decaying military machines, and abandoned and vulnerable alien soldiers seeking refuge amidst the ruins. In this bleak landscape, the player leads the last survivors of humanity, facing difficult choices and uncertain alliances as they navigate the chaos.

The player can choose from several factions, such as humans, the mysterious entities of the Voice, or the automatons of ZEPHON, each with unique abilities and characteristics. Tactical choices and resource management are crucial as settlements must be built and defended, new technologies researched, and diplomatic maneuvers must be engaged in to ensure the survival of civilization.

The game features over 50 unit types, each with specific skills, weapons, and characteristics that can be combined, along with combat tactics, to confront alien threats. There are also three development paths (Human, Voice, and Cyber) that allow the player to customize their strategies and combine powers in innovative ways.

The combat experience is enriched by the possibility of carrying out special tactical operations, which include technological interference, supernatural abilities, and even the use of nuclear weapons. In addition, in multiplayer mode, the player can use special leader abilities, either facing friends or allying with them to face danger.

Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.
