Zanki Zero: Last Beginning is a dungeon crawler in which players explore strange ruins, dungeons, and giant islands in a post-apocalyptic world. The game was developed and published by Spike Chunsoft Co., Ltd. on April 10, 2019.

While it took God seven days to create the world and everything on it, humans needed just one to destroy it all. The entire world sank down to the deepest depths of the sea, and no one knows exactly what happened to make this happen. Now, only pieces of civilization drift around. Cars, buildings, houses, asphalt, everything connected to modern civilization is now just debris that is floating on the surface of the sea.

In Zanki Zero: Last Beginning, players pick between one of eight unique protagonists in each of the game's chapters and go through many towers, islands, and dungeons in order to reveal the sinister sins hidden deep within their past. Only the most capable will survive in this world. Search for food and monsters, slay powerful monsters in real-time battle environments, and always remember to go to the bathroom from time to time.

Each of the clones has only 13 days in one life cycle. Stats, abilities, and capabilities change with their age. Bonus upgrades can be earned depending on the way you die. Can you guide each of these clones into this world and figure out what destroys it?
