Welcome! As Mordheimer said, this is a GREAT intro into larger 40k games. We have taken a lot of the core mechanics of 40k and implimented them into this game, so when you move to 40k it will not be that hard to adjust.
When I started with this game I had only played 40k, and within 2 games I had Death Squads pretty much figured out. It won't take long for you to get into the swing of things!

Adeptus Astartes Commandments
1. Thou shalt not replace the Librarian's staff with a magic wand.
2. Though shalt not refer to thine brethren, whom the Emperor has dictated be armed with an incendiary weapon, as a "Flamer" constantly. For this has been proven to lower morale and cause strife within His Most Holy showering facilities.
3. Thou shalt not follow a Librarian around thinking, "Can you hear me now", repetitively in an attempt to drive him insane.
