Alpha makes some adjustments to his weapons then shifted his left arm into a cannon, he had made it into a flamethrower. "All units with flamethrowers, burn these pests but do not damage the structure!" He opens fire, quite literally as bursts of hot flame erupted from the cannon at the centipedes.
Seraphicon slices, he dices and shreds the centipedes that got anywhere within range of his attacks, covering any gaps with shots from his rifle. He was trying to be careful to not hit his fellow Cybertronians.
