After all this time playing the game I just realised (what a genius) that even a freshly new created PC cannot die from a single shot from, let's say, a blaster rifle.
I just thought of the situation where a PC is fighting a Stormtrooper (let's suppose this trooper has Agility 3 and Ranged heavy 2). Well, the trooper cannot kill the PC with a single hit of his blaster rifle unless the PC was already critically wounded, no matter how lucky the trooper may be (like rolling two triumphs or so).
Combat is fast and furious in this game (soak monsters aside), but all of a sudden the game does not seem that lethal to me anymore. Just a random thought.
