What the developers have to say:

Why Early Access?

“We are using the early access so you can help us finish the game. We want your feedback on the current gameplay as we continue to update and add more content to the game.”

Approximately how long will this game be in Early Access?

“We expect another year of development to the game before we are happy that everything we wanted has been added and is working well. We have a lot of additional content that we are currently creating which we would like to see in the game before it's final release.”

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

“The finished game will have a lot of new features and will be more optimized than it’s current early access build, we have to delegate our time between bug fixing and adding this new content. Early access will allow us to hire more staff to the team to help speed up this process and make this the game we are excited to deliver.”

What is the current state of the Early Access version?

“The current game is running 99.9% stable. All features listed below are already in the game.”

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

“The price will very likely increase as we approach the release of the game and ship new content and features.”

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

“As mentioned involving the community into the development is a critical and important task in the early-access phase. During early-access we intend to try out game-mechanics for the game which you may like or dislike, your feedback on those mechanics is very important to us. We also would like to invite you to leave suggestions about the game and it's mechanics on our forums.”

Alpha Update 1.2.2

Hello Everyone,

While we are still actively working on cleaning up multiplayer, we have some new toys for a few to enjoy.

We do have a Discord channel for those interested as well.

    -The Infamous 'falling through the terrain at the game start' bug should be dead. If you receive this update and are still experiencing this, please post on the Discord channel.

    -Fixed the orientation of holstered long guns and tweaked postioning of all weapons in 1P ADS.

    -We added a Tactical Shotgun and the MP7A1 to the weapons complement. Currently, these are only available in Sandbox mode but will be integrated into the main game soon.

    -Extensive tweaks of weapon damage and accuracy. The numbers are based on the stats of the real world weapons, although they have been adjusted slightly for balance. This is another area where feedback to our Discord channel is greatly appreciated.

The primary focus on the next version will be cleaning up the Multiplayer experience even more. We have a pretty good understanding of what's causing the desync issues that many players have seen and we're working hard to resolve them swiftly.

Alpha Update 1.2

Hello Everyone,

We have been actively working on making Outbreak: Pandemic Evolution making the game that we personally want to play. That being said, it has been no secret that when we took over the project there were a lot of core gameplay mechanics, bugs, and features that were missing. We appreciate all your support and patience and can't wait to fix what is here and begin adding our new content and ideas. We are sure that you guys are going to enjoy the direction we are taking the game.

We'd also like to welcome industry veteran Scot Bayless to the team. Scot has decades of AAA game experience and will be heading up Outbreak: Pandemic Evolution and its team going forward.

We do have a Discord channel for those interested as well.

    Alaskan Cedar branches no longer block attacks. This was happening from only one direction which is why you could sometimes end up getting shot by an AI while simultaneously being unable to shoot back.
    Chain link fences no longer block attacks.

  • AI
    Player movement now affects ranged enemy accuracy. Basically, the faster you run, the lower their chance to hit. The effect is range dependent. At close range, running won't help you much. At long range, it'll help quite a bit.
    Crouching now affects enemy accuracy. As with running, range is a factor.

    Some general improvements have been made on the rendering side. This should get most players a noticeable boost in overall perf.

    We've been tweaking the 3P camera to improve on the parallax problem that can cause you to shoot cover that's in front of you even if your sight shows a clear shot. It's still a work in progress and, at the moment, 3P aiming with long guns is a little frustrating since your target can be obscured by your head. When fighting with long guns, the 1P view is probably your better choice at the moment.
    The FOV change when aiming has been changed to zoom your view in a little tighter. This happens in both 3P and 1P and is intended to give you a better sight picture when you're aiming.

  • UI / UX
    Changed the font in existing UI elements to improve readability, especially on smaller monitors. We have also added a version text to the HUD to help make reporting bugs easier going forward.
    Largest Fan Request! We also added a compass to the top of the HUD to help navigation and communication going forward.

This isn't a full roadmap. At the moment, we're focusing on knocking down the really egregious bugs and on nailing the fun in moment to moment gameplay.

  • AI
    More improvements in enemy AI. The goal here is to reward smart tactics, use of cover, etc. More distinct differences between types of enemy. Each type should present clear and unique tactical challenges. In combination, these could get pretty hairy, but then that's kind of the point.

    While basic FPS gameplay works pretty well over the wire, there are a TON of serious sync issues in MP. These are mostly associated with unique game objects and with character spawning. Our goal for the next update is to clear this list of bugs completely and it's currently our #1 priority.
    We're investigating the potential of an option to use cloud-based game servers. We don't have a timeline for this, but it's something we believe can greatly enhance some of the bigger online features we're looking at.

    There are a huge number of content bugs that need cleaning up. We probably won't get them all in the next patch, but we hope to clear many of them. Much of the game still needs lighting love. Expect to see continuing improvements as we work our way through this list.

    Along with the AI improvements, we're looking at, we have a growing list of gameplay tweaks. These range from weapon damage tuning to crafting tweaks and even major new features (which we cant' talk about just yet).

    We've received some reports of in-game crashes. Hopefully our cleaning up of the latest code will help, however, if you experience a crash, please know that we are actively looking at the possibility that some of the desync issues may be causing this. We are looking to fix this as soon as possible.

About This Game

Outbreak may look like a first-person survival game and while it has quite a few survival elements that are there to distract you from your mission the game is played completely different.

In Outbreak 2 factions, military and mutants, fight over areas. The military is trying to stop the mutant outbreak while the mutants are attracted by electricity and increase in numbers each time one of them dies. You, as the sole survivor of a high-tech research facility dug into the mountains, have to figure out how to stop the mutant threat. Capture them alive and experiment on them to find a cure. Push the military back and stop them from interrupting your power-supply while mutants are attempting to raid your facility. Put up defenses to fight-off the ever increasing attack waves of mutants. Craft tools like motion-trackers, turrets, landmines & weapons. Experiment on mutants and find the toxin. Capture areas in the game to weaken the factions and manage your facility.

The factions in the game fight each other on the map. It is up to you how you influence this fight - taking out military troops and cleaning up areas will strategically weaken them as they are loosing ground & numbers. Mutants are a bit harder to stop as you first have to figure out how to push them back which also requires capturing one of them alive, they also evolve over time and you will see more variations of them.


The game allows you to play coop with friends, hosting your own servers you can control who joins your game. Time is essential as the longer you play the larger the outbreak will become as it spawns out three classes of Mutants, each one larger and more deadlier than the last.

Core Features

  • Single-Player and Faction-based Co-op Survival. Play alone or with your friends who can join at any point of the game through steam.
  • Dynamic Story-Telling and Event System. (See Below)
  • AI Personality Profiles : Combat is dynamic, the AI might flank you, run away, call for help, depending on the situation and each NPCs personality. This is especially the case on the military side.
  • Beautiful Open-World with dynamic Day & Night Cycle, already optimized for average PCs.
  • Crafting System, which allows you to create weapons and upgrades using different types of machines in your facility.
  • Building System, allows you to reinforce & upgrade your base.
  • Looting System, each area in the game has different types of loot, you might find an area with a lot of resources for your base while other regions have higher chances for personal items like weapons, upgrades and supplies.
  • Food/Drink System balanced to a level where it is fun. We added it to add strategy to the game, not to annoy you.
  • Blueprint System. Find blueprints to gain access to more craft-able items.
  • Faction AI System, non-scripted fights between mutants, military and you.
  • Decision System, the game has been designed to react to your decisions.
  • Capture System, areas of the game-world are contested and can be captured.
  • NEW SINCE UPDATE 6 - Cooking System, hunt or scavenge raw food, then cook them in your facility.
  • NEW SINCE UPDATE 9 - Wildlife has been added.
  • NEW SINCE UPDATE 12 - Mission/Objective System has been added.

Storyteller/Event System

There are two factions fighting, the mutants and the Military. You must survive in this war but you can also influence the outcome as each faction spreads over the map. The military will order air strikes against the mutants and try to hold key locations such as the town and their own military base, they will call in air supplies that can be intercepted. The mutants will also try and take over the map and will eventually try to over run your base if they are not stopped. You have your own agenda of survival and both the mutants and military will kill you on sight. The game will try to stop you any way it can and no two games will be the same thanks to the story telling mechanics that bring the two factions to war.
