Outcast in Mars

The Heymll 3.7 model robot is activated on the surface of the planet Mars with the mission of finding the souls of all humans that have been transferred to the server hosted on the planet. Souls belong to users of the sinister social network known as the Holocordio. Holocordio uploaded the souls of users connected to the network shortly before a zombie apocalypse occurred that killed 98% of the earth's population. This is the premise of the introduction of this adventure.
