Update 0.75: Operation White Rose Highlights

The White Rose update has reshaped the game’s meta. Here’s what players are focusing on this month:

  • New Units: The Phantom Captain and Sharpshooter are powerful new additions, especially effective in high-difficulty winter maps.
  • Ice Gifts Currency: A limited-time resource used in the Winter Shop. Codes like Engage! let you skip early grinding and grab exclusive cosmetics faster.
  • Auto-Upgrade Feature: A highly requested quality-of-life update now allows auto-upgrades to be toggled in settings, making long wave runs much smoother.
  • Event End Date: Operation White Rose runs until January 24, 2026, so be sure to spend all Ice Gifts before the event ends.
