Toxin rebel

"This will teach them!"

- Toxin Rebel using its poisons

Toxin Rebels were Dr. Thrax's own special Rebels eschewed the usual assault rifle in favour of a toxin-spraying weapon with backpack toxin-tank (similar to a flamethrower). This made them effective at eliminating infantry, even ones garrisoned in buildings and bunkers. Like normal Rebels they could garrison buildings and be trained to capture buildings at a Barracks.

Be wary of using them in crowded areas or ordering Toxin Rebels to march over a recently-sprayed area, as they can potentially be harmed by their own toxins.

Counters
