The video doesn't show off the juicy bits of the construction, because the whole thing is terribly messy and inefficient, but it does show the concept in a functional state on a multiplayer 1.4.6 server.
Also, yes I'm still alive
and when your gone I'll be... Still alive...
To those interested the server is the newly created HazardCorps minecraft server, Our group is mainly an APB:R clan but we do play other games (of course) minecraft being one.
While we're not against people joining the server, it is not public for various reasons.
Invites are sent to people we know and/or have actually gamed with.
