Long-range network relays are buildings designed to collect with other Relays.
Relays require 20 build packets before operation starts.
Relays are able to make long-range connections with other Relays. That is, about 2.5 times the length of a normal network connection. Other than that, it offers no special benefits.
Like all production structures, Relays have little structural integrity; even a glancing blow from Creeper will cause it to destabilize and collapse.
