This mod is about a creepypasta called Entity 303, he can affect the player and the world.
Description
With this mod, entity 303 is added to the world automatically, its presence is imperceptible at first but the more time passes, the stranger things happen, and it all starts from a "303 joined the game" message.
I won't tell you especifically what can entity 303 do, because thats the mistake of most horror mods, they need to be unpredictable.
This mod has this command:
----> /force303join # If you don't want to wait for him to join by himself, then just force it ;)
WARNING!!!!! ---> Entity 303 will destroy and corrupt your world so don't use this mod in an important world!!
