The lack of support thing is very odd, they seem to just pump things out with little in the way of planning. If Kill Team is an intro game then it needs a version of the usual 40k rules.

I hope it isn't an intro game but rather a different focus on 40k conflicts with extra detail if anything. What appeals to me is the chance to get a usable force (rather than an army) from an unfamiliar faction.

As the Lord Damocles said, Necromunda and Shadow War make me doubtful that this game will tick the right boxes for me. Still, I'd settle for a solid game even if unsupported.
