So I'm running the first mission of The Emperor Protects at the moment and it looks like the kill-team will soon be getting up close and personal with some genestealers. However, looking over the stats it seems to me as though they are horribly overpowered. With the stats given in the book they each have 2 80% dodges per turn. When you factor in the -20 to hit from hard target it really seems a little ridiculous. I've got no problem with the ungodly amount of damage they do, they are stealers after all. However from what I can see it looks as though a single genestealer running in a straight line at a battle brother across an open field has a very good chance of getting around all his fire, matrix style, and tearing him apart, I don't think it's supposed to work like that.
On the other hand, a horde of genestealers, not having access to dodge, will fall like so much wheat before the scythe.
Has anybody come up with more usable stats? However I run this encounter it looks like it will be unsatisfying. Either the Kill-team gets raped by 5 or 6 individual genestealers or I throw a horde at them and watch the heavy bolter cut it down in one or two rounds. Plus it just seems silly for them to be so much more formidable when not in a horde.
