The Regretavator was a fun place, there was Infinite levels full of fun and joy, till when Unpleasant threw a infected Rat at Kasper, everything changed.

The players stopped coming, the NPCs got infected one by one. Mark and wallter, who was a couple, promise to never leave each other. Till one day, prototype had told mark and wallter That mark was infected, wallter was immune though. He watched lampert (their adoptive son) get infected and die and he didn't want that to happen too mark.
