Rat Killer Robot Invasion holds the better App Store score, 4.6 against 3.8.

Written reviews complicate that: 86% of BoxHead vs Zombies 2's written reviews are positive against 31% of Rat Killer Robot Invasion's, so the app with the better star average is not the one people write more warmly about.
BoxHead vs Zombies 2 ships an update every 13 months, Rat Killer Robot Invasion every 10 days. The most recent releases landed on September 25, 2026 and October 15, 2026 respectively.
