Double Switch - Pre-Played / Incomplete

The chopper kicks up dust as it sets down. Through the haze of dirt and grit you make out El Cadron, a shabby little Texas border town. It looks quiet enough. But folks have been disappearing. And as a tactical expert, you soon discover it's crawling with aliens disguised as humans. Welcome to Ground Zero Texas. Armed with four BattleCams outfitted with a particle beam to stun the aliens (you can't kill them with traditional guns), and a RoverCam used to search out the Reticulan weapon stash, you're in for a sci-fi, wild west gun fest.
