So my group and I had a "discussion" about when you die. Is it when you go past double your wound threshold or once you reach your threshold, its double from there? Example: Say my wound threshold is 10, I take 10 wounds and go unconscious. From there do I die at 10 more wounds, or 20 more wounds from there (30 wounds total)?

Neither. It's when you have a critical injury that results in death. You just stop counting once double your wound threshold, 20 in your example.

There are 2 parts to this. A PC dies when they get a crit that says so at 140+ on the crit table. An NPC dies when they run out of wounds and the GM says dead or they get a crit of 140+ IE if a minion is reduced to 0 wounds they may or may not be dead at the GMs discretion. The same rule applies in vehicle combat. Reducing a PC vehicle to 0 hull does not mean the ship blows up. That only happens when you get a crit that says so. But minion ships likely go boom at the GMs discretion.

Ok so basically the crits keep stacking till the roll is high enough to kill them

Yep. Remembering each crit your suffering adds 10 to any further crit rolls.

Also only a single crit can be inflicted on a single hit, each crit on a single hit after that adds 10 to the roll.

But as Daeglan said these rules are only strict for PC's, when it comes to NPC's the GM has a lot of flexibility to tell a good story.

There are a few issues in this comment.

• First "reduced to 0 wounds" means perfectly healthy, this system counts up, not down. Also they become incapacitated at 1 wound over their threshold, not right at the threshold.
• Minions die on critical, but there is a choice if they die on wounds.
  • There is a bit of confusion on the way it is typed up though, it states in bold a minion is killed on a critical injury, but it states in the text it is merely incapacitated. So technically both answers are correct.
• Just like on NPC characters, vehicles also count hull trauma up and not down. Additionally it is at 1 damage over the hull trauma that it is incapacitated.
  • Also even at 140+ for a critical hit, the GM can choose to have the ship crash, and the crew inside not die (but they would suffer a critical injury each).
