What's New in Tanklet
1.3.3
September 12, 2026
Abyss Season opens on September 28 — this update gets everything ready. · The season is easy to find: a season capsule on the home screen counts down to opening day and jumps straight to the season page, which gets a brand-new hero. In the shop, the Abyss Egg sits at the top with a Limited badge. On opening day, a one-time intro shows what the season has in store. · Safer on a new device: on first launch, Tanklet now restores your tank from iCloud before deciding whether to start a new one — no more surprise second tank. · Multi-device fix: weekly task progress no longer gets overwritten by an older snapshot from another device. · Levels now start at 1: new keepers used to begin at level 2. The unlock pace is unchanged; longtime keepers may see their level number drop by one, and everything already unlocked stays unlocked. · Achievements can now be opened from Settings, with your completed count shown. · Plus assorted fixes and polish. Coming from an older version? 1.3.2 brought 50 species, weekly tasks with a pass, and 33 achievements — plenty is waiting to be claimed.
