About this game

Astrafort is an incremental space defense game where every battle makes you stronger. Command a lone fortress, withstand relentless enemy waves, and combine powerful upgrades to push farther than ever before.

1. DEFEND YOUR FORT

Fight increasingly dangerous enemies and powerful bosses. Improve your attack, defense, and utility systems during each battle to survive the next wave.

2. BUILD PERMANENT POWER

Invest your credits in the Factory to permanently strengthen your fortress. Research upgrades in the Academy, unlock new systems, and prepare stronger strategies for future battles.

3. CREATE YOUR BUILD

Choose from a wide range of upgrades and perks. Fire critical shots, bounce and ricochet bullets between enemies, reinforce your shield and hull, or build an economy that grows stronger with every wave.

4. KEEP PROGRESSING

Continue battles through offline simulation, automate battle upgrades, complete daily and weekly missions, and reach milestones that unlock new levels and features. Your progress is backed up to the cloud, so it survives a reinstall or a new device.

Astrafort features:

* Strategic wave-based space defense
* Extensive attack, defense, and utility upgrades
* Permanent Factory upgrades
* Academy research that progresses over time
* Common, rare, and legendary perks
* Offline battle simulation
* Automatic battle upgrades
* Cloud saves and progress restore
* Multiple levels, enemy types, and bosses
* Daily missions, weekly rewards, and milestones

How long can your fortress survive? Adapt your strategy, expand your power, and stand against the endless assault.
