Compared to Chrono Miners, Ultra Miners are faster, amphibious, more durable and resilient, carry twice as much ores (the same as a Soviet War Miner), and armed with a negation field like that used by Pacific Front Suppressors to protect itself from enemy raids.
The AI will deploy an Ultra Miner automatically when it is off cooldown. Only Normal and Hard AI will create Ultra Miners; Normal AI will only have a maximum of 1 Ultra Miner while Hard Ai will only have a maximum of 2. Any created Ultra Miners will target any nearby enemy infantry.
- In Fullmetal, an Ultra Miner is given individually during the mission, marking its first appearance.
- The Warp Miners is first usable in the campaign in Insomnia, where the player is suggested to use Warp Miners to collect ore at the other side of the base.
