# Chicken Invaders 2 HD vs Atlantis Invaders

The clearest difference is review sentiment: Chicken Invaders 2 HD at 100% against Atlantis Invaders's 31%. Chicken Invaders 2 HD also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Atlantis Invaders's advantage is update cadence (fortnightly vs every 34 months) and rating (4.7 vs 4.3). On price and in-app purchases there is nothing between them.

Both are free to download. Chicken Invaders 2 HD sells 1 one-off in-app purchase and Atlantis Invaders sells 70 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Atlantis Invaders holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Atlantis Invaders has 2.8K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 100% of Chicken Invaders 2 HD's written reviews are positive against 31% of Atlantis Invaders's, so the app with the better star average is not the one people write more warmly about.

Chicken Invaders 2 HD ships an update every 34 months, Atlantis Invaders fortnightly. The most recent releases landed on October 22, 2026 and October 27, 2026 respectively.
