One thing I'm having trouble figuring out is why there are so many damage types when they have no different effects or defenses. Bullet and Pen and a couple others. Especially when according to the example damage types don't stack against defenses so Pen doesn't even make it easier to penetrate armor. Given that most weapons with Pen also have Bullet I'd almost think it should do half damage after armor but always be applied to armor first or some such thing.
I'm sure there was more discussion of damage types somewhere in one of the versions but I can't find it in the book.
It also looks to me like the armor values are very high relative to the damage values if like damage types don't stack against armor.
I did finally get a book, though it came from my distributor, which is pretty disappointing. Especially since, when I first talked to them about T5 they didn't even know it was coming and hadn't seen the kickstarter.
