Coming Soon To Early Access

What the developers have to say:

Why Early Access?

“Bunker Buster is playable and fun right now, but we want to build it with the community. Early Access lets real players tell us what's working, what needs balance, and what features would make the game even better. Your feedback directly shapes what gets built next.”

Approximately how long will this game be in Early Access?

“We estimate around 6 to 12 months, depending on community feedback and the scope of improvements we want to make before a full release.”

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

“We plan to expand the game significantly based on player feedback. Areas we're looking to develop include additional enemy factions and captured weapons, more room types and bunker systems, a campaign or progression mode, deeper tech tree branches, balance improvements across all weapon and defence systems, and additional multiplayer features. The core base-building and combat experience is already in place, the full version aims to broaden and deepen everything around it.”

What is the current state of the Early Access version?

“The game is fully playable with complete base-building, real-time tactical combat, ten enemy factions each with unique capturable weapons, a research and upgrade system, life support simulation, and Steam multiplayer including fortress raiding and PvP quickmatch. Some systems may still need balance tuning and there may be bugs, that's exactly why we're in Early Access.”

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

“We plan to increase the price when we leave Early Access, as the game will have grown significantly in content and scope. Players who support development early will get the best price.”

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

“We'll be actively monitoring Steam discussions and community feedback to guide what we work on. Players can report bugs, suggest features, and vote on priorities. We plan to post regular updates describing what changed and why, so the community can see their input having a direct impact on the game.”
