Missile magazine

"as missiles are used they will draw from nearby magazine slots in the direction specified!"

Missile magazines act as ammunition for missile systems. Missiles will automatically travel between adjacent magazines toward a launcher so long as one of the magazines is placed immediately behind the missile tube. The simpler missile tube is single use and cannot be reloaded using missile magazines. If a warhead converter is used all missiles in any magazines anywhere on the ship will be converted.

Trivia
The magazine feed system actually works in reverse, each time a missile is loaded an empty magazine will propagate between magazines until it has no neighbor to spread to.
