Synth Retention Bureau is an organization within the Institute tasked with capturing escaped androids (or "synthetics").

This is a gmod group despite the name, based primarily on wire and e2.

There are no group servers yet and will be quite a while (as it must be made) but please refer to X_X Server by Copet V for a good build server.
