# Galaxy Attack vs Chicken Invaders Universe

The clearest difference is ratings volume: Galaxy Attack at 3.4K against Chicken Invaders Universe's 32. Galaxy Attack also leads on rating (4.7 vs 4.5). Chicken Invaders Universe's advantage is review sentiment (68% vs 53%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Galaxy Attack sells 17 in-app purchases, starting at $4.99 per 7 days and Chicken Invaders Universe sells 9 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Galaxy Attack holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Galaxy Attack has 3.4K ratings behind it against 32, so its average is the more settled of the two. Written reviews complicate that: 53% of Galaxy Attack's written reviews are positive against 68% of Chicken Invaders Universe's, so the app with the better star average is not the one people write more warmly about.

Galaxy Attack ships an update every 3 months, Chicken Invaders Universe every 6 weeks. The most recent releases landed on October 24, 2026 and October 22, 2026 respectively.
