Strategy[edit]

  • Any Leader Power that can lead all enemy units to frozen (Such as Glacial Storm, Cryo Bomb, and units frozen from Cryotech Advances), have your units focus fire on it to defeat them instead of moving to another target.
  • Seismic Blast is not effective against unfrozen units, but it's very effective against frozen units.
  • Cryotech Advances practically slows down any infantries attempting to capture a Power Node. This, however, was ineffective for any units under Let 'Volir's Leader Power, Banished Raid and Captain Cutter's Leader Power, UNSC Raid as they can de-capture Power Node faster than other units.
  • Have Kodiak as the Main Strike Force as Cryotech Advances augments the Kodiak's shell with the chilling effect, effective for crowd control and demolishing building faster.
  • If the player wishes to rush, quickly obtain Frostraven to make immediate suppression on enemy units.
