Secret map

[reptile]

Recently I joined a server that had a single player map for multiplayer. It let me use a turrent and it had bacta despensers on the wall. It was like a mission at kashyyk. It had other people there talking so I know it was multiplayer. I know it wasnt a sandcrawler thing because  I used my regular version of republic commando. Any ideas on what this is and how it happened :?: ,I would like to know how to do this. :D

Its just the single player map opened on a Multiplayer server...it will most likely crash as soon as you get to any AI. There is really no point, but you just use a Open command with one of the SP map instead.

So I have to host to do it?
