The Tempest is a Goo anti-air ground unit.

The Tempest "juggles" three projectiles suspended in the air above its body. These projectiles can be launched at enemy aircraft, exploding on contact.[2]


Built to ascend to towering heights on terrain to gather weather readings, the Tempest evolved to watch the sky, but for a different reason. Three projectiles are suspended above its body at a time, striking any enemy aircraft that comes overhead and exploding to infect any other aircraft in the formation.


  • Tempests can climb onto high terrain, allowing them to gain a large vantage on the skies and land around them.
  • The Tempest loads three shots at a time, and must reload after firing them off.
  • Shots fired from the Tempest not only damage the enemy they strike, but also generate AoE damage that affects any nearby enemies.
