I ended up googling and think I figured out lead genestealers weapons.
It’s like GW has decided that only 40K players want it. They’re not catering for newcomers.
Primarily I’m in this for the terrain and was thinking of using the genestealers in Necromunda as White Dwarf published an article with genestealer stats.
I already have forge bane, so got quite an army of Adepptus Mech.
A friend of mine also bought kill team. I might see if he wants to trade armies.
