# Zombie Evolution vs Slime Evolution 2

The clearest difference is ratings volume: Zombie Evolution at 2.1K against Slime Evolution 2's 14. Zombie Evolution also leads on rating (4.7 vs 4.4) and review sentiment (82% vs 73%). Slime Evolution 2's advantage is update cadence (every 9 days vs every 6 weeks) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zombie Evolution sells 12 one-off in-app purchases and Slime Evolution 2 sells 8 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Zombie Evolution holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Zombie Evolution has 2.1K ratings behind it against 14, so its average is the more settled of the two. Written reviews point the same way: 82% of Zombie Evolution's written reviews are positive against 73% of Slime Evolution 2's.

Zombie Evolution ships an update every 6 weeks, Slime Evolution 2 every 9 days. The most recent releases landed on October 6, 2026 and October 4, 2026 respectively.
