Also, unlike the Predator Tank and Scooper, Scorpions can attack aircraft, while in defensive positions. Scorpions are unlocked, by default, for defense. But may be purchased, for the offense role, for 1.5 million Research Points and 600,000 Credits. Their upgrade is Laser Cutter, which increases damage to infantry caused by the Scorpion running them over. It costs 250 million Credits and 500 million Research Points.
