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 1.5.8

A quick note.

After playing through the game with the community last night, it became abundantly clear that you should keep your score even when you die. So, we worked hard today to make sure that priority became reality. As of tonight, your score will be maintained even when you die in the game. This makes achieving the badges and a higher score 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.

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.
