開發者的話:

為何採用搶先體驗模式?

Cepheus Protocol is a large game still in active development. Early Access lets us keep shipping improvements while working closely with the community. There will be bugs and rough edges, but your feedback directly helps shape what we build next.

How often do we update?
We push minor updates and bug fixes regularly, usually at least once per week. Hotfixes go out as needed when issues impact gameplay.

Bigger feature updates land every month or two. These often appear first in our Experimental build on Steam so players can test new systems early without disrupting the main branch. Once changes are stable and polished, they roll into the core game.

Major updates
Major builds like 1.0, 1.1, 1.2 and beyond take longer because they combine multiple large changes across gameplay and content. Each major build focuses on improving core systems and expanding the game with new mechanics, units, weapons, vehicles, animations, and locations. Because we are a small team, some features may be developed by only one person at a time, which can affect timelines, but we share progress often through previews and developer streams.

Community involvement
As major updates get close, we invite the community into the Experimental build to test and give feedback. After collecting feedback for several days or weeks, we make the needed fixes and adjustments before pushing the update publicly. We do internal testing first, but community testing catches real world edge cases fast.

Bug fixes
We aim to fix serious issues quickly and keep you informed when something takes longer than expected. If you are reporting bugs, thank you. That is a big part of what makes Early Access work.

What can slow development?
Sometimes progress is impacted by engine updates, tool changes, team availability, or unexpected issues. Even when that happens, we will stay transparent, keep communicating, and keep moving the game forward.」

這款遊戲的搶先體驗時間大約會持續多久?

「We will remain in Early Access until Cepheus Protocol is feature-complete and polished. We do not want to lock a hard date that forces a rushed release, but our goal is to reach 1.0 as soon as we can while maintaining quality.

Early Access exists so we can keep shipping updates, gather feedback, and improve the game in real conditions. Your support and bug reports directly help us get to a stronger full release.」

正式版預計會與搶先體驗版有何不同?

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

We plan for the full version of Cepheus Protocol to be broader in scope and more feature-complete than the current Early Access build. Early Access is focused on improving core systems, expanding content, and using community feedback to refine balance, performance, and overall gameplay flow.

Planned additions and scope
We plan to support multiple ways to play, including:
  • Pandemic Mode expanded and polished as the core sandbox experience
  • Co-op features and progression improvements where they make sense for the mode
  • Horde Mode with additional missions and long-term replayability
  • Special Operations style missions with more directed objectives and scenarios
  • Story or Campaign content delivered in a form that fits the game’s systems and pacing

Overall improvements
Beyond new content, we plan to raise the quality bar across the board compared to Early Access, including stability, performance, UI, onboarding and tutorials, animations, balance, and long-term progression. As development continues, priorities and scope may evol

搶先體驗版目前的開發進度如何?

「Right now, Cepheus Protocol Early Access is fully playable in both single-player and co-op, with RTS squad command and TPS Operator gameplay available.

  • Single-player and co-op support: Play solo or with others, with flexible gameplay across both modes.
  • TPS Operators and joint missions: You can play as TPS Operators and run missions together, combining hero-style Operator combat with squad coordination.
  • Missions available now: A selection of Horror missions and Pandemic missions you can jump into immediately.
  • Operator progression and RPG mechanics: Operators feature RPG-style progression, letting you build and grow your hero over time.
  • Operator customization: Customize your RTS and TPS heroes to fit your preferred playstyle.
  • Doctrines and specialization: An assortment of Doctrines acts as a specialization system, letting you choose branches like a skill tree to unlock units, upgrades, and passive bonuses as you progress.[/list\

遊戲售價在搶先體驗期間前後會有所變動嗎?

「Yes. We plan to raise the price in steps as Cepheus Protocol grows.

Our current plan is:
  • A small price increase after the conclusion of our upcoming reveal period, currently targeted around Q1 to Q2 2026.
  • Another small increase when the game leaves Early Access and reaches full release.

We will provide advance notice before any price change.

If you buy the game during Early Access, you will receive the full release version automatically at no additional cost.

在開發過程中,您打算如何與社群互動?

  • Feedback and bug reports: Players can share feedback, balance notes, and bug reports through Steam discussions, Discord, and social channels. We use that input to guide fixes, tuning, and priority decisions.
  • Experimental branch testing: New mechanics, systems, and content are often released first on our Experimental Steam branch so the community can test changes early and help us catch issues before they hit the main build.
  • Developer communication: We share progress through patch notes, dev previews, and live developer streams, especially around major features and larger updates.
  • Iteration based on results: When feedback shows something is not fun, not clear, or not balanced, we adjust and refine it. Community testing helps us validate what works in real gameplay.

“A game that caught me off guard with how freaking fantastic it is, it runs fairly darn well, is pretty intense and reminds me quite a bit of They Are Billions just in a more modern world.”
SmashGaminG

“I'm really into Tower Defense games and this one is a great creation. It keeps you easily entertained. The sounds and graphics are decent. It's still in E.A and it looks pretty good so far.”
~8.2/10 – Kawaii Reviews

“Cepheus gameplay is a unique blend of RTS with a real tower defense feel. 100% a strong learning curve to master the tactical skills layered across the six different character classes. Check it out!”
Mature Minded Gamers
