ReceptionRating · Positive reviews · Number of ratings

BUNKER PROTOCOL holds the better App Store score, 4.8 against 4.0.

Written reviews complicate that: 51% of Escape #2's written reviews are positive against 0% of BUNKER PROTOCOL's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Escape #2 ships an update every 2 months, BUNKER PROTOCOL weekly. The most recent releases landed on September 19, 2026 and September 24, 2026 respectively.
