The Echoes Update

1.2
12 August 2026
12 changes in this update

Added

3 changes

  • Six new upgrades that only unlock by Surging, so a new era opens with something you have never had access to before rather than the same tree again.

  • Residual Charge, Muscle Memory and Second Sun - permanent Cores upgrades unlocked at 1, 2 and 3 Surges, covering critical damage, combo grace and a global multiplier.

  • Echo Chamber, Flux Saturation and Origin Recall - Energy upgrades unlocked at 1, 2 and 3 Surges, available from the very first run of a new era.

Improved

2 changes

  • The Rebirth panel now previews permanent upgrades you have not unlocked yet, showing what they need instead of hiding them completely.

  • Bulk buy no longer offers more levels than it can actually deliver when an upgrade is close to its cap.

Fixed

4 changes

  • Progress bars were broken for players outside English-speaking regions. The achievement completion bar and the Rebirth progress bar both failed to fill because of how decimals are written in other languages.

  • The top bar could push content off the edge of the screen on smaller windows now that it carries a fourth currency.

  • The Surge confirmation ran its sentences together instead of reading as separate paragraphs.

  • Hardened the game against malformed network messages in multiplayer.

Known Issues

3 changes

  • Selecting MAX and then maxing out an upgrade that has a level cap can briefly stretch that upgrade's card downwards. Cosmetic only, and still being investigated.

  • Multiplayer works but has had very little testing with real players.

  • Global rankings may take a few minutes to reflect a brand new record run.
