Been running games on and off with several of the former Ex testers, they have an uncanny knack for getting themselves killed in deeply silly ways.
visit a derelict ship in the warp - dead
knock themselves out in front of a sentry turret - dead
attract the attention of another Inquisitor while supposedly being undercover - dead
However currently due to time restraints and other stuff, were not DH'in, i can however point you at
http://www.darkreign40k.com/ which is a fairly decent site for all things DH.
