# Galaxy Attack vs Project Entropy

The clearest difference is ads: Project Entropy at none against Galaxy Attack's shown. Galaxy Attack's advantage is review sentiment (52% vs 25%) and ratings volume (654K vs 1.4K). On price, in-app purchases, monetization model and chart position there is nothing between them.

Both are free to download. Galaxy Attack sells 15 in-app purchases, starting at $9.99 per month and Project Entropy sells 13 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Galaxy Attack holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Galaxy Attack has 654K ratings behind it against 1.4K, so its average is the more settled of the two. Written reviews point the same way: 52% of Galaxy Attack's written reviews are positive against 25% of Project Entropy's.

Galaxy Attack ships an update every 4 days, Project Entropy every 2 weeks. The most recent releases landed on September 25, 2026 and September 22, 2026 respectively.
