Level Unknown: Unknown: An Epic Litrpg Adventure

An Epic Fantasy LitRPG perfect for fans of Dungeon Crawler Carl and He Who Fights With Monsters.

Conquer the artificial world. Level Up. Save humanity.
When an ancient alien artifact chooses research cadet Nick to explore the world stored within it—a place full of forgotten empires, heroes with strange powers, and monstrous creatures that he is automatically transported to when he sleeps—he finds he has no choice but to grow stronger within the realm of Yensere to uncover its mysteries. 
But Yensere isn’t all fun exploration. In this land guided by statistics and levels, Nick is seen as a demonic threat by its diseased inhabitants and always killed on-sight. When he dies in Yensere, he awakens in his bed upon the research station, his body in a state of panic; when he sleeps again, Yensere drags him back for another life...and another death. 
Nick can only keep this up for so long before he dies for real. But there’s a good chance Yensere holds the key to saving humanity from a terrible fate, and so he ventures on, getting stronger and stronger with each new enemy defeated. And there are a LOT of enemies to defeat…
