Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Arsenal 2 holds the better App Store score, 4.5 against 2.9. That said, the two scores are not equally well evidenced: Arsenal 2 has 933 ratings behind it against 23, so its average is the more settled of the two. Written reviews complicate that: 33% of Pluto Trigger's written reviews are positive against 29% of Arsenal 2's, so the app with the better star average is not the one people write more warmly about.
Pluto Trigger ships an update every 5 months, Arsenal 2 monthly. The most recent releases landed on September 27, 2026 and October 13, 2026 respectively.
