kinda new to being a gm

By axaxel, in Dark Heresy Gamemasters

so im kinda new to playing and this will be my first time being a gm. for the beginning of my story i wanted all the acolytes to be overwealmed in act one, but only knocked out so that way they can wake up later in a new enviroment kinda like they where kidnapped.

my only problem is i cant think of a reasonalbe way to knock them all out.

at first i was thinking gas but i think a few of them have rebreathers and such. so i was wondering if anyone else has tried this before and how they would go about doing this

Poisoned food is an option (everyone needs to eat eventually); make Hard Toughness test 1 hour after eating or gain 1d5 points of Fatigue, plus 1 point per Degree of Failure. That's still not a sure thing, so whoever is trying to knock them out needs to have some people standing by with Shock Prods to finish the job (or better yet a Psyker with the power Psychic Shriek).

thanks that helped alot :)
