For A Reason

The rover takes off as you input the western marker into the map. An hour passes as the rover speeds through the grasslands. Everywhere looks the same. you start to think you are stuck in some sort of loop, where everything is the same, when you see a large tower ahead of you. the sun is starting to set so you must act quickly, before the darkness will cover the land. by the looks of it, this building is also abandoned. as you get near you see the tower is much smaller than you initially thought, 40 feet tall at most, and very thin. on top of the tower is a large circular panel with some sort of rod poking out of the center. at the bottom of the tower is a large control box with a screen. you walk up to the screen and it reads out, "provide a valid Z - TECH identifier to access COM tower" You have nothing but the rover, which is "ZT" approved, so maybe it will work. you grab the disk from the front of the rover and the map turns off. you plug the disk into the control box and it brings up a new screen, "EMERGENCY PICKUP ACTIVATED PLEASE HOLD." you must have called in support by accident and in around 10 minutes ships of all size and shape enter atmosphere. they all land in synchronization and all have the backwards Z symbol. they look to be soldiers and are covered in heavy armor and each have long rifles. they leave their ships and circle around you. one of them looks different, their helmet is differently shaped, they seem to be higher ranked. the higher ranked one walks up to you with a pistol and points it directly into your suit's visor, "IDENTIFY YOURSELF IMMEDIATELY"
