What the developers have to say:

Why Early Access?

“We chose Early Access to involve our community in the development of the game from the very beginning. We want players to participate by sharing their ideas, suggestions, and feedback to make the game more fun, balanced, and suitable for everyone. Our vision is to create a game that is shaped by both developers and players.”

Approximately how long will this game be in Early Access?

“We expect the game to remain in Early Access for approximately 9 months, but this may change as development progresses. Our goal is to ensure the game reaches a level of quality and content that meets the community’s expectations before the full release.”

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

“We plan to expand the game with new content throughout development, such as new maps, weapons, and additional challenges. However, these updates will depend on community feedback and the overall progress of the project.”

What is the current state of the Early Access version?

“The Early Access version is now functional and offers the core game experience, with core modes defined, playable maps, and support for testing co-op multiplayer. While it is currently in a playable state, we are still working on adding content, making balance adjustments, and resolving technical issues to improve the overall experience.”

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

“No, it will have the same price without changes.”

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

“We plan to actively engage with the community through the Steam forums, social media, and YouTube. We’ll be listening to player feedback to fine-tune gameplay, balance modes, and prioritize improvements. We’ll also be holding playtests and testing sessions to ensure the community plays a key role in the evolution of the game.”

About This Game

🔥 Sinister Outbreak – You woke up in a nightmare. Now fight your way out.

You wake up in a dark, deserted laboratory... and it's far too quiet. There's no memory of what happened — just blood on the walls and the sound of something approaching. Something that is no longer alive.
Welcome to Sinister Outbreak, an action-packed game set in a chilling atmosphere of horror and survival.

🧟‍♂️ Survive the unexpected

Explore dark corridors and abandoned rooms, where every corner may hide unspeakable horrors. Armed only with what you can find, you’ll face brutal zombies and out-of-control experiments as you search for answers — and a way out.

🔫 Intense action with a touch of horror

Blending combat with moments of pure tension, Sinister Outbreak puts your reflexes to the test. Manage your ammo, solve puzzles, and try to make it out alive. Not everything can be faced head-on.
