Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We want to develop Outbreak Horizon alongside our community. Building a high-scale tactical shooter with massive crowds, responsive multiplayer combat, and multi-faction engagements requires continuous player feedback. Early Access allows us to refine weapon balancing, optimize crowd performance, expand game modes, and fine-tune cooperative mechanics based directly on real player experiences.”

Approximately how long will this game be in Early Access?

“We anticipate Outbreak Horizon will remain in Early Access for approximately 6 to 12 months. This timeline allows us sufficient time to implement community feedback, optimize performance across diverse hardware configurations, and introduce planned content milestones before the official full release.”

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

“We plan to expand the game with additional content and deeper tactical mechanics, including:
• Expanded urban and quarantine sectors with new tactical choke points.
• Additional military weaponry, customizable loadouts, and support equipment.
• More varied infected archetypes and bandit faction behaviors.
• Additional multiplayer scenarios, expanded objective-driven modes, and refined VOIP features.
• Ongoing performance optimizations and community-requested quality-of-life improvements.”

What is the current state of the Early Access version?

“The current Early Access version offers a fully playable core experience featuring:
• Core three-way tactical warfare involving military squads, massive infected swarms, and hostile bandit factions.
• Working multiplayer conquest modes and cooperative squad missions.
• Integrated positional proximity voice chat (VOIP).
• Functional military weapon mechanics, ballistics, and tactical positioning systems.
• Stable crowd simulation delivering dense waves of infected enemies.”

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

“We plan to offer Outbreak Horizon at a lower price point during Early Access to thank early adopters who support development and provide critical feedback. As we implement major content milestones, introduce new modes, and polish the game toward the 1.0 release, we plan to moderately increase the price to reflect the expanded scope and feature set.”

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

“Community feedback is vital to Outbreak Horizon's growth. We actively engage with players through our official Steam Community Hub and Discord server. We closely monitor bug reports, weapon balance suggestions, crowd performance feedback, and feature requests. Regular development updates and patch notes will keep the community informed of upcoming content and changes shaped directly by their input.”

About This Game

CONTAINMENT IS YOUR ONLY ORDER

A deadly viral outbreak has struck, plunging the region into absolute chaos. As a Military Commander deployed alongside your squad directly into the heart of the quarantine zone, your mission is absolute: maintain order and hold the line at all costs.

As emergency protocols collapse, massive hordes of infected rapidly overwhelm defensive positions across the sector.

THREE-WAY TACTICAL WARFARE

  • US Military Forces: Command your squad, execute tactical orders, manage high-caliber firepower, and defend critical choke points under extreme pressure.
  • The Infected Swarms: Face terrifying, dense crowds of infected enemies filling every approach, powered by high-scale crowd simulation.
  • Hostile Bandit Factions: Armed lawless gangs have seized upon the panic, ambushing military checkpoints and fighting for control of vital supplies.

ONLINE MULTIPLAYER & CO-OP

  • Multiplayer Conquest Mode: Fight alongside other players for large-scale control across intense combat sectors.
  • Tactical Co-Op Missions: Squad up with friends to execute high-stakes PvE objectives behind enemy lines.
  • Proximity VOIP: Communicate in real-time with integrated positional voice chat—keep your squad close, as only nearby players can hear you.

KEY FEATURES

  • Intense Tactical Combat: Lead your team, utilize military-grade weapons, and deploy strategic positional defenses to suppress escalating threats.
  • Massive Enemy Crowds: Stand your ground against overwhelming swarms of fully animated infected entities pressing against your defensive line.
  • Multi-Faction Encounters: Adapt your strategy on the fly as military operations intersect with hostile bandit ambushes and relentless zombie waves.
  • Firepower & Resource Management: Balance aggressive shooting with strategic squad positioning to prevent containment failure.

Can you execute your orders, keep your squad alive, and hold the quarantine line, or will you be swallowed by the crowd? Survive the collapse in Outbreak Horizon.
