I developed the Useful Unknown Signals Mod as a means of placing limits on gathering resources using the SE Unknown Signals game mechanic.

This guide has information about each container, where it spawns (planets; moons; space), how often it spawns (spawn rate 0.5=less often; 1.0=often; 1.5=more often), contents and any additional notes/functions.

Notes contained in guide regarding blocks, contents and special functions is by exception. It is assumed, all containers have similar base blocks, such as battery, parachute, cargo container and button.
