  • New Unit Variant Strike Hound: Increases Hound’s ATK 270%, but increases ATK interval by 2.6s


  • Subsidized Steel Ball Card Level 2 → Level 3
  • Projectile (Flame) Movement Speed: 250/s → 450/s

  • ATK: 88 → 84 (-5%)

Developer’s Note: Thanks to Mathismight for bringing this to our attention in a Reddit post. We have inspected the projectile movement speed of all units in the game. After extensive testing, we found that the movement speed of the flames emitted by Vulcan significantly affects its effectiveness against light units. Tests have shown that the adjusted Vulcan has improved efficiency against various types of units. Therefore, we have slightly decreased Vulcan’s ATK to balance it. In our tests, the new Vulcan with reduced ATK is still stronger than before in most cases.

  • Projectile (Bullets) Movement Speed: 300/s → 420/s
  • Projectile (Flame) Movement Speed: 200/s → 400/s (Special effects optimized)
