What the developers have to say:

Why Early Access?

“BioGun is our love letter to the Metroidvania genre, and we want to make it legendary! Early Access lets you join the adventure early and help us craft the ultimate experience. We're a small but passionate indie team, pouring our hearts into this game and we truly believe your insights will also help us polish the experience further. Are you ready to save the dog kind?”

Approximately how long will this game be in Early Access?

“Our current target for Early Access is around 3 months, but we're keeping an open mind! We'll adjust this timeframe based on your feedback and how development progresses. Our top priority is ensuring a smooth launch for the full version of BioGun.”

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

“BioGun's Early Access lets you experience the core gameplay mechanics and world structure we've been working hard on. We plan to use your feedback to refine the experience and additional content, add more languages and polish the game for the full release. Depending on Early Access results we will also consider adding more organs to explore.”

What is the current state of the Early Access version?

“BioGun's Early Access version features all the organs/areas that are required for the main story experience. You will be able to beat the game from start to finish, which is a solid starting point, and we're actively working on improvements based on your input.”

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

“We plan to maintain a consistent price throughout Early Access without increasing it on the full-release”

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

“We want to hear from YOU! We'll be hanging out on Steam discussions, Twitter, Reddit and our Discord server, soaking up your feedback and suggestions. Every voice matters, and we'll be keeping you in the loop about how your ideas are helping BioGun evolve. Let's build this awesome game together!”

“BioGun looks like a fantastic voyage.”

“By making death potentially rewarding rather than punishing and leveraging the game's shooter-style combat system, BioGun manages to carve out a distinct identity in a genre saturated with sameyness.”
Game Rant

“BioGun is a sci-fi Metroidvania game with a fantastic premise.”
