# Backpack Attack vs Bullet Fusion

The clearest difference is rating: Backpack Attack at 4.6 against Bullet Fusion's 1.6. Backpack Attack also leads on ratings volume (144 vs 5). Bullet Fusion's advantage is review sentiment (29% vs 17%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Backpack Attack sells 20 one-off in-app purchases and Bullet Fusion sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Backpack Attack holds the better App Store score, 4.6 against 1.6. That said, the two scores are not equally well evidenced: Backpack Attack has 144 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 17% of Backpack Attack's written reviews are positive against 29% of Bullet Fusion's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 4 days. The most recent releases landed on September 21, 2026 and July 7, 2026 respectively.
