About this Mod

Lost Radar is a companion mod for Lost Cities. It adds an item (a radar) that shows a map of the city around the player. It also has a feature to search for specific buildings. While this mod works in combination with vanilla Lost Cities it is actually meant to be used in modpacks with specifically configured building categories. Note that the radar item requires energy in order to function.

This mod was commissioned by TqLxQuanZ.

You can use this mod freely in any modpack.
