Oooh, that was my review.
Basically, when someone fires a burst at someone, instead of having any real fancy complicated rules, the number of bullets hits depend on the attack roll. If you just make the attack roll, then 1 hit, if you beat it by 5, then 2, if you beat it by 10, then all 3. And so on. (most guns only fire a 3 round burst, but some 5 or more, so it depends on that))
I like this because it represents how the first bullet is usually the most accurate, and the further ones in the burst usually start to deviate more. And it's pretty easy.
The suppressive fire rules I also like. Basically, you can spray an area with bullets (minimum of 5 bursts), and the attack roll (minus 4) is applied to anyone in the area. Then anyone in the area that could have been hit by the attack roll makes a reflex save vs. the number of bullets used. Usually a DC of 15 (since that is the minimum rounds firde for suppressive fire) , but higher for more bullets. Machine guns, which are meant for suppressive fire, usually have 5 rounds per burst, so the minimum save DC is 25.
Also, easier for me to remember.
