One man. One tower apocalypse. One year to escape before everyone dies.

So I woke up to find the world had ended. Not the worst news ever.

That part came when my apartment building transformed into a 100-floor tower of traps, monsters, and loot. Oh, and every resident has just one year to escape the tower before they're killed.

Then the System made me a Blood Reaver. A Class that allows me to heal myself with the blood of my enemies. Great. I'm sure no one will look twice at a guy drenched in blood all the time.

Armed with the finest steel that twenty bucks at Larry's Kung-fu Emporium could provide, I set out with my crow companion Hugo to descend the tower. But when each floor is deadlier than the last, the allies are few, and the monsters are many. The only path forward is through blood.
