Actualy the idea of an underground base with alot of high rankin millitary personal and equipment with starmaps abaut how the war is going etc would fit the kdf warmachine concept. Could be their, base of operation where they plan wich sector/system to attack, where to send reinforcments etc.
Last time I did it, I jumped behind the counter where the vendors are in the NW corner outside the pub. The wall behind them wasn't solid and I fell into the abyss.
There is also a spot near the R&D area, where you go up the ramp heading for the slum district, you can walk thru the wall by the ramp and fall through as well.
I figure it'll get fixed after a couple years or so...
