Generators, research and reactor missions
Combine incremental growth with decisions during missions. Increase energy production, unlock upgrades and return to resources earned offline — then adapt the reactor settings to each campaign objective.
Campaign: power and shields
54 campaign missions and 12 modules to choose from. Balance production, cooling and shields. New challenges unlock as you progress.
Gameplay: power routing ↗Research and core reboots
Research, core reboots and offline production. The campaign uses its own units without inflating the main currency.
Screens from the Polish game. Emulator with prepared QA saves, not natural progression.
More power. More decisions.
In missions, output alone is not enough. Allocate your power and adapt as conditions change.
Pick a goal. Find your next step.
The new command center suggests where to go next. Grow your reactor and discover more systems when you are ready for them.

Where did you get stuck?
Tell us what felt unclear, where the wait was too long and which choice felt rewarding. For a bug, include the game version, phone model and reproduction steps — never passwords or private information.
- Is it clear what to do when you first open the game?
- Which purchase feels rewarding, and which takes too long?
- Does power routing make sense in your first mission?
Before you start your reactor
In an idle game, you develop a system that produces resources automatically. In CORE//FORGE you buy generators and upgrades, and offline production lets you collect energy when you return, up to the current limit. Campaign missions add active power, heat and shield management.
Yes. The current closed Alpha is free, with no ads or in-app purchases. You need Android 8 or later and access to Google Play. This is a development build; a progress reset is planned before launch.
The first chapter requires your first core reboot. Later chapters unlock as you progress: complete the previous chapter and meet the sector and research requirements. Not all missions are available from the start.
Check all three steps and the active Play Store account — it may differ from your browser account. Make sure you joined the group, not just opened its page. If you are in the internal test, leave it before joining the closed Alpha. New access can take time; if the problem persists, contact us. Do not clear your game data.
No. A Google account is needed to join the Google Play test. Separate registration inside the game is optional.
We do not ask for ratings or artificial activity. If you can, stay enrolled in the test for at least 14 days and play at your own pace. Honest feedback about why you return — or stop playing — helps most.
