Aliens have attacked El Cadron, a small border town in Texas. You've arrived to save the townspeople, who've been disappearing. These aliens have clever ways of disguising themselves as townspeople. Your mission is to do away with them, but they can't be killed with regular guns. You're armed with four Battlecams, with a stunning practice beam that stops the alien temporarily. Your RoverCam scans the landscape in search of the Reticulan weapon arsenal. Although once you find this, make sure you're ready to defend yourself, because they will attack.
