▶Available in StoreThe Signal Jammer is a Jammer which hides the world. When broadcasting or messaging others, it will come up as the world name JAMMED! The world is also not visible through the world selection screen, no matter how many people are in the world.
However, people can still join the world if they know the world name, or, if they find the player through the friends list. It also does not hide the world during a friendcast.
- When placed, players can get the "This land is my land" achievement, if they have not placed a World Lock before.
