Are the stats for genestealers in the ark of souls book?

Genestealers are in the ark of lost souls, mark of xenos, final sanction, and there's also some user created content floating around the internet. Just search for genestealer cults pdf, but I think it's not made for DW, so maybe needs some transformation. But it has a lot of additional information on genestealers.

Blood Angels vs Genestealers is classic of course but how about an Eldar warhost trying to resurrect a Pheonix Lord?

Meanwhile the ordo Xenos Inquisitor that sent the team in is keeping his cards close to his chest. His plan is to steal the body from the Eldar but has given a different mission to the Deathwatch/Space Marine Chapter.

my advice is DO NOT start off with storm bolters and terminator armor.

let them work up to that. seen as a reward.

maybe tell them their squad is recon and scouting for now,

and other senior squads in other quadrants are doing the heavy fighting.

if they do well as as scouts, they may get promoted to clean up work.

start on level one and progress naturally, I say
