Terraria is a former map from the original Murder Mystery 1 and it is also based off the two-dimensional game, Terraria. Terraria resembles a medieval obstacle course, with two castles and a lake in the middle. In both castles there is a sky house and if you jump off the sky house at a certain spot, you will be glitched on top of a tree. This is commonly used however and isn't really a hiding spot.
This map has been discontinued in 2015 due to unknown.
