What the developers have to say:

Why Early Access?

“We're releasing in Early Access because as a small two-person team (Kaira Interactive), we want to build this game alongside our community rather than in isolation. Multiplayer survival games live or die by balance, server stability, and player-driven emergent moments — things that can only be properly tuned with real players testing real sessions at scale. We're fully committed to ongoing development: regular updates, responding to feedback, and seeing this project through to a complete, polished release.”

Approximately how long will this game be in Early Access?

“Roughly 6–12 months, depending on community feedback and the scope of features we add based on player requests.”

How is the full version planned to differ from the Early Access version?

“The full version will expand significantly on the current base-building and raid systems, adding more building pieces, defensive structures, and base customization options. We plan to add additional weapon types, attachments, and progression systems, expanded zombie variety with new AI behaviors, additional maps/biomes, deeper base-raiding mechanics and further polish to networking stability and performance. We'll also continue expanding social and Steam-integrated features such as leaderboards and achievements based on community demand.”

What is the current state of the Early Access version?

“The current Early Access build now includes multiplayer co-op gameplay in addition to the demo mode. Players can now survive together in the same session, build bases, and fight off zombies. We've also added the ability to join other players' sessions and launch "raids" on their bases. All other features listed in the About This Game section above are also implemented in this build — please refer to that section for further details.”

Will the game be priced differently during and after Early Access?

“It's going to be the same price.”

How are you planning on involving the Community in your development process?

“Community feedback will directly shape our development priorities — bug reports, balance feedback, and feature requests from players will guide what we focus on in each update. We'll primarily communicate through [] and Steam community discussions, where we'll share development updates, gather feedback on new features before they're finalized, and run polls on upcoming content priorities.”

About This Game

Zombie Defense: Breach of the Undead is a survival-focused zombie defense game built around constant pressure and escalating danger. Your goal is simple: hold your ground, survive the waves, and last as long as possible.
But with every wave, the undead grow stronger, faster, and more ruthless.

Using limited resources, you must build your defense, choose your weapons carefully, and adapt your strategy as endless zombie hordes breach your position. Fast-paced combat, dark atmosphere, and intense moments define the experience.

  • Wave-Based Zombie Attacks
    Each wave introduces tougher and more aggressive enemies.

  • Weapons & Defensive Tools
    Multiple weapons and damage styles to fit different playstyles.

  • Dark and Tense Atmosphere
    Sound, lighting, and environment design create constant tension.

  • Smooth and Responsive Gameplay
    Performance-focused mechanics with clear feedback.

  • High Replayability
    Every run is a new challenge with a different outcome.

There is no escape.
