what is DEFRAG?

Cleanse corrupted sectors by upgrading nodes and combining modules to defeat viruses.

DEFRAG is a sci-fi strategy game focused on eliminating viruses and optimizing sectors. Players collect resources to upgrade nodes and combine them for new combat styles. Challenges and higher difficulties reward strategic planning and system refinement.

It sits in the Management / Strategy / Sci-Fi corner of the genre. Like most idle games it runs on a simple loop — earn, reinvest, automate — but the depth is in how long that loop keeps unfolding. Expect to check in, make a few decisions, and watch the numbers climb whether you're at the keyboard or not.
