We've embedded their bios and intro videos below:
Killer and healer in equal measure, crash into Conduit and you'll quickly get wise to the hand you're being dealt. A force of nature manifested by the green glow of his repairing weapons, Conduit keeps his allies pumped and fighting for their faction.
Former vigilante, Front-Line was always first to gate-crash and last to exit the most depraved crime scenes. Now a titanium-tough Autobot, Front-Line deploys his own brand of justice on the battlefield. Annihilating enemy shields with his minigun, frenzied axe and hammer attacks bang out more bodywork than a Cybertronian chop shop.
