Played a one-shot of this over the weekend.
I enjoyed the direct writing style, the rules were clear and easy to grasp. This ran out the box with little difficulty, though I would appreciate a glossary for key words. There were a few times where looking up a gameplay term using control F still didn't lead me to a clear definition and I had to root around.
The greatest success here was marrying the Resistance System beautifully to the "GRIM DARKNESS" of the 40K fiction. There is an inevitable, grinding tragedy to this game that just hits that exact, beautiful tone that makes everything Dan Abnett's ever written so darn good.
Thanks for the fun.
