# Chicken Invaders 3 HD vs Sky Force

The clearest difference is review sentiment: Sky Force at 89% against Chicken Invaders 3 HD's 25%. Sky Force also leads on rating (4.7 vs 4.1) and ratings volume (2.1K vs 41). Chicken Invaders 3 HD's advantage is ads (none vs shown) and iOS requirement (8.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
