Serum is an FPS RPG game focusing on survival and PvP. Players compete against each other gathering Serum and Relics.
The planet Cronus contains the most valuable and energy dense fuel humanity has ever discovered, Serum. The controlling federation has prohibited unauthorized mining. With the recent discovery of inter-dimensional travel those restrictions have become impossible to enforce. Individuals and factions have begun jumping between universes to simultaneously reap what remains of Cronus.
You are a reaper of Cronus. You command a ship along with a regenerative droid that you control from orbit. The droid is deployed from your ship onto Cronus. The mission is to extract as much Serum from the species of Cronus.
You are not alone. Others have again started reaping Cronus. Although split across multiple universes, chances are you will come in contact with another reaper. Be wary, the Serum you collect can be extracted from your droid. Trust noone.
The technology that powers your droid is also fueled by Serum. To prolong your harvest make sure to keep enough Serum in reserves to power your droid. If your droid dies or runs out of Serum a new one will be created and dropped back onto Cronus.
