In Roblox Slayers Unleashed, you are playing a character based in the world of the anime Demon Slayer. You will need to fight your way through dangerous enemies and attempt to survive by becoming a Demon, Slayer, or a Hybrid! There’s breathing and demon arts to obtain, and you will need to obtain a powerful clan if you want to make it to the top of the ladder!

We’re featuring a look at the most recent update logs for the various patches that the game has received. The game receives pretty frequent updates, so not every patch is a major one.
