The EXP-Series of combat android, was an expendable model with a modified First Law of Robotics to cause harm to humans and had a lifespan of several weeks. In hostage situations this would make this version of synthetics useless as a hostage as a squad of Colonial Marines found out on a Xenomorph-infested world.
The EXP combat androids are armed with Splatterguns and M41E carbines.
A Lasalle Bionational assassin by the name of Massey commanded a ship full of this series in 2192 in interfering and stopping a classified Terran Government mission to acquire an xenomorph sample for weapons research. The synthetics, armed with splatterguns invaded the USCM vessal, The Benedict and managed to take the crew and compliement of Marines hostage due to sabotage by a double agent. The androids were sent planetside with the hostages to herd the hostages into the local hive to be fodder for the xenomorphs.
Due to unforeseen circumstances, several Air pods crewed by two androids each were attacked by local flying creatures destroying several Air pods and androids. This allowed a squad of Marines to arm themselves and fight back, taking down more air pods and sniping stranded androids. Any androids that survived the encounter with the Marines were destroyed by the nuclear bombardment by the Marine Sergeant Wilks on board the ship.
