...during our last live session we actually rolled some dice and calculated damage :-)

I suppose it worked well enough - we learned that small puny assassins that get jumped by big cats are in trouble. We also learned that autofiring splinter weapons with toxic ammo are quite deadly (or paralytic) - but fortunately a little less so if you have the antidote already administered.

The real problem as I see it is how Wounds work as a buffer. As long as you have them you're basically OK, but one you run out even a relatively weak attack can cripple or kill you.

In Haxtes' case he lost a lot of wounds to the cat, but never enough to take any real injuries (i.e. was Heavily Wounded, but he had Wounds left, so no critical damage). But once he came aboard the hulk and people started shooting at him he was even mortal peril with each an every shot. And these were just 1d10+3 shots vs. DR 6.

We need a mechanism that simple and elegant, but that doesn't mean you're more or less auto-dead once you're out of Wounds. It just doesn't make any sense the way it works now - it's  like a scaled-down version of DnD, just without any of the benefits of simplicity.

So I'm looking over at RuneQuest2 again (did the same for the skill system revision - it's one of the few good new d100 systems available). RQ2 has a Wound (or hit points) total, but also has Wounds divided by hit location where to sum of the body parts is greater than total Wounds. As long as a body part has wounds you're OK (light wound), but as soon as you go into the negative you're penalized (heavy wound), and if you get far enough into the negative you're crippled or dying (critical wound). The subtle difference with this system is that you can take an injury to one bdoy part during one attack, and still have wounds left elsewhere.

Had we been using this system Haxtes would have had his arm ravaged by the cat, losing function with the arm (and presumably received some medicae attention afterwards). But he'd still have wounds left, so that when the Dark Eldar started firing at him he arm would have been somewhat vulnerable, but he'd be more or less OK overall (well, maybe no OK, but a bit better).
