What's New in Aether Bastion

1.2.0

October 16, 2026

• Now plays on iPhone Duo: portrait on the outer screen, landscape when you unfold. • Hub tabs now fit without crowding. In landscape they move to a side column, and Play spreads into two columns. • In landscape, the rift HUD stays clear of the screen edges. • The in-run shop is easier to read and tap on smaller iPhones, including iPhone SE. • Grow tabs stay in order as they unlock, and Game Over buttons take you to the right place. • Balance: Brood regenerates half as fast, so late Rift 5 waves are easier to hold. • Daily gems can be claimed once per Apple ID, across all your devices. • iCloud saves sync more reliably, and gem purchases are counted correctly across your devices. • Deleting your account now removes your data from every device and from iCloud. • Company claims can't be tapped again while one is pending.
