You were a worker drone, one day on october 29 3071, a landing pod had crashed far from your colony, you and your group went to investigate and 3 screens with glowing yellow X's (which looks more like "><" also the 3 drones are J, V and N) they fly out slicing one of your Coworkers head off and holding it and then dropping the head and they fire missiles at you and your Coworkers.
