"Nice to meet you, Commander! Cryoneer reporting in. My Freeze Beam can seriously reduce the firepower of enemy defenses. It's also great for cooling beverages and making ice sculptures!"


  • The Cryoneer is unlocked at Headquarters level 20, making it the tenth troop to unlock.
  • They periodically fire bursts of penetrating cryogenic beams, slowing any defenses and troops that enter the line of fire, while also dealing light damage to buildings.
    • They do not deal damage to troops.
    • Affected defenses recieve a 50% fire rate penalty.
  • Unlike other area-of-effect troops such as the Grenadier, their weapons do not trigger Mines.

Offensive Strategy

  • Cryoneers will disperse themselves to cover as many targets as possible, and they will periodically switch targets in battle.
  • Since they slow down the firing rate of enemy turrets, effectively reducing their damage output by a percentage instead of a raw number, they are extremely useful for supporting other troop formations like Heavy-Zooka even on bases with very high damage boosts like Gearheart or upper-level Operation bases, unlike Medics whose raw-point-value healing effect gets quickly overpowered in these situations. The Heavy-Zooka-Cryo formation can be incredibly effective, as Heavies buy the much-needed time for Cryoneers to disable critical defenses.
  • Cryoneers can also be used in the RZCM strategy, or the Rifleman-Zooka-Cryoneer-Medic strategy. This strategy uses Riflemen as meatshields, Zookas to deal damage, Cryoneers to cripple defenses, and Medics to heal. The Cryoneers will slow down Machine Guns and Flamethrowers, allowing the Riflemen to stay alive longer.
  • It is not recommended to use Cryoneers with Scorchers, as Scorchers will neutralize their freezing effects, and they may unintentionally slow the Scorcher.

Defensive Strategy

  • Cryoneers have moderate health so a Cannon or Boom Cannon can take her down in one shot if it is high-leveled.
  • Due to this moderate amount of health, a few salvos from a Rocket Launcher or a few shots from Mortars may also work on wiping out a few Cryoneers at once.
  • Avoid clustering defenses whenever possible because this provides Cryoneers the opportunity to freeze more defenses at once.

Upgrade Differences

  • There are no visual changes between levels, but each upgrade increases the Cryoneer's hitpoints (by 9%), DPS (by 5%), beam extension (by about half a tile) and training cost (by 1000 gold).


  • According to a Loading Screen Hint, the Cryoneer's freeze ray was developed using technology from Dr. T's Cryo Bomb.
  • You can have a maximum of 56 Cryoneers in a complete set of fully upgraded Landing Crafts.
    • Note: As Cryoneers have poor offensive capabilities, having this many of them is not recommended.
  • They are currently the fastest-firing troop. However, this only accounts for when the beam is being shot. There is an approximate 3.5 second delay in between attacks.
  • The sound of ice shattering can be heard when a frozen building is destroyed.
  • The name 'Cryoneer' may be a portmanteau of 'Cryo' (the Greek prefix for "cold") and 'Engineer'.
  • The Cryoneer, along with Sgt. Brick are voice acted by Marissa Lenti.
  • The Cryoneer has dozens of catchphrases which can be viewed by tapping her info button in the Armory or Landing Craft. She is also the only troop to have multiple catchphrases. Almost every single one of these is either a reference, a pun, or both. They include, but are not limited to the following:
"Ice. Ice. Baby"
"Allow Me To Break The Ice"
"All The Cool Kids Are Doing It"
"Don't Need Hot Pants To Look Cool"
"I'm A Special Snowflake"

"Winter is Coming"
"Let It Go"
"Science is Cool!"
"Humble Pie Served Cold"
"I'm A Stone Cold Freezer"
"My Game Froze!"
"Cool It, Hot Stuff"
"Snowblinded Me With Science"
"Cool Party!"
"Iceberg Right Ahead"
"Cold Spell Coming"
"The Ice Age Is Coming"
"Feel The Chill"
"Polar Express to Freezeville"
"Take A Chill Pill"
"Frostbite Me"
"Feeling Warm, Punk?"
"It's Getting Cold In Here"
"Ice To Meet You"
"Get the Cold Shoulder"
"Need Some Frosting?"
"Be Ice Now Kids!"
"Stay Frosty!"
"Cool It, Buster!"
