Ex. what is the difference between Heavy2D3 and Rapid Fire 1 etc. ?

I haven't seen a formal description of all types, but it's known that heavy weapons mean you pay a -1 penalty to hit when you move, and shoot.

Assault weapons can advance and still shoot, at a -1 penalty I believe.

And I *assume* you can charge after firing any weapon type, because Storm Bolters are Rapid Fire 2.

hm, what about weapons listed as Heavy2D6 and Heavy4D3 for ex?

You roll 2d6 and make those 2d6 shots (or 4d3) with the rules of -1 to hit if you moved.

Advance seems to be like "Run" in AOS. +d6" movement, and you can shoot assault weapons (at -1) if you run.

ok, so with 2d6 if i rolled a 4 and 5, i would make 9 hits or i would make two successful hits (if it was bs4 for example)?

That would be 9 shots (4+5), so you'd roll 9 six-sided dice to hit, and with a 3+ to hit, each dice of those 9 that is a 3 or higher would be a hit.

It's no different than now. Heavy 2d6 means you get 2d6 shots, so if you roll a 9 that's the same as if the weapon had said heavy 9.
Basically everything in 8th is an assault weapon like we have now. that is you can move,shoot assault.
Heavy means that you get a -1 penalty to your to hit rolls when you actually did move and assault allows you to run and shoot at the cost of also getting a -1 penalty, where as rapid fire hasn't changed (except for being able to assault after shooting).
And well, you can have rapid fire (X) where before ti was simply rapid fire. So rapid fire 2 means you shoot twice at max distance and four times at half.

In short, it works like this:

Normally: If you Advance, you cannot shoot or charge. If you are within 1" of an enemy model, you cannot shoot. A model may fire either all their pistols, or all their non-pistol weapons. Each weapon can be fired at a different target. Each model can fire at different targets.

Assault X: You can fire X shots. If you Advance, you can still shoot, but at -1 on the to-hit roll.
Rapid-Fire X: You can fire X shots. At half range, you can fire 2X shots.
Pistol X: You can fire X shots. If you are within 1" of an enemy model (in combat), you can still shoot at the nearest enemy unit.
Grenade X: One model per unit may fire a grenade instead of their other weapons. You fire X shots.
Heavy X: You can fire X shots. If you move in the Movement phase, these shots are made at -1 on the to-hit roll.

If the X is a die roll instead of a fixed number, you roll the indicated dice and fire that many shots. These are shots, not automatic hits or wounds (unless the weapon's profile states that it always hits, like a Flamer). That's just like variable-shot weapons now, like the Serpent Shield.

That's a nice summary. What he said^^.

Fantastic summary, thank you.
I think I've got it now. So you'd roll to determine # of shots (in the case of a weapon with 2d6) and then roll to determine hits based on BS, and then roll to determine wounds based on your strength or weapon strength vs their toughness? And then the opponent would roll to determine saves (armour+cover)?

I'm just confused by the Heavy2D3 (like on the whirlwind vengeance launcher). Why roll 2d3 instead of 1d6?

So there is no difference between staying stationary & shooting vs moving & shooting when using something like a boltgun?

2D3 Allows for at least 2 shots rather than 1 with a shoddy roll also help keep things more consistent when shooting

As Sqauwky points out, yeah, the difference is variance. Look up the distribution of possible results between 2d3 and 1d6 - on 1d6, each result is equally likely, on 2d3, the results tend to "clump" in the middle, so it's more consistent.

With Rapid-Fire, Grenade and Pistol weapons, movement does not affect your shooting unless you Advance (used to be Run/Turbo-Boost), correct. Also, you can charge after shooting, no matter what you fired. You can charge a different target from the one you shot at, too. Great for, say, having some Assault Marines fly up and thin out some Boyz with two flamers and a frag grenade while the Sergeant pops off a combi-melta shot at a Trukk, then they charge some Gretchin that are holding an objective. Generally a lot more versatility in each unit now.

Oh, combi-weapons: no longer one use only, and you can fire both profiles at once. If you do, you get -1 to hit.

awesome. thanks folks.

yeah combi-weapons seem great. and plasma pistols to use in combat.
