The massive Scorpitron, a tank with an armored warrior, is by far the deadliest robot the Desert Rangers will have to face in post holocaust Las Vegas. With an automatic tail-mounted cannon, tons of armor and significant resistance, it can destroy an unprepared party in just a few turns. Unprepared Rangers will not survive.
It is recommended to engage the Scorpitron at maximum distance and pelt it with rockets, laser arms and other high end weaponry to wear down its armor and blow it to kingdom come. Though, if one is equipped with high end armor, it may be of interest to train undeveloped skills for a promotion, or simply for that purpose only.
