Flame troopers are available as an option for Arcturus Mengsk in Co-op Missions. They are upgraded from Dominion troopers for 160 minerals, and gives them the ability to attack multiple ground enemies at short range, specializing against light targets, though they lose the ability to attack air. This suit also gives the trooper an additional 100 hp, an extra point of armor, and change their armor typing from Light to Armored. When a flame trooper dies, their gear will fall on the map, and another Dominion trooper can pick them up and upgrade themselves. The weapon will also drop if the unit swaps itself to a Dominion laborer.
When this unit becomes Indoctrinated by an imperial witness, it increases Imperial Support by 1. Each point of Imperial Support generates 1 Imperial Mandate every 240 seconds.
When Amplified Airwaves is researched, Imperial Support is increased from 1 to 2. Mastery: +0.01 (+0.02 with Amplified Airwaves) Imperial Support per Laborers and Troopers Imperial Support mastery point. Up to a maximum 1.3 (2.6 with Amplified Airwaves) Imperial Support.
Dominion trooper and laborer select, move and attack quotations change depending on the level of Imperial Mandate the player has. At 34 and below, they are more reluctant, at 34-67, they are more "regular," and at 67 and above, the quotes are patriotic and assured.
