Hullo,
The group I game with were unhappy with the d20 Modern rules for handleing automatic fire weapons and thus we have been experimenting & tinkering with our own. I thought I would post it here to get some feedback. Our new system required re-writting the Burst Fire feat and the Strafe Feat. Plus how to handle the effects of suppression.

We came up with these rules after discussions with an Australian army machine gunner who was also was unhappy with the d20 Modern rules.


FEAT: Controlled Burst Fire
With this feat the character can control the automatic fire from a machine gun or other automatic fire weapon.

Benefit: The player may opt to make ether a Burst Fire Attack or a Suppression Attack.

Burst Fire Attack – As an attack action the character fires a burst of bullets at one specific target. An attack roll is made per bullet-fired equal to the weapons rate of fire stat, with an accumulative –2 (maximum -6) modifier to each attack roll after the first. The character may continue to fire the burst through subsequent actions but the modifiers continue as if these connected actions were the same attack.

Suppression Attack - As a full-round action the character may perform Suppression Fire. The weapon fires a number of bullets for the round equal to double the weapons automatic rate of fire stat, with an area effect of 10ft x 10ft or 20ft x 5ft. A suppression attack lasts from the characters initiative number to the same initiative number on the following combat round, characters with this area or who enter the area during the attack are effected by the Suppression Attack. Those effected must make a Suppression Check (see New & Special Rules: Suppression) and a Reflex save of DC 10 + half the characters total attack bonus (round down). If the Reflex save is failed the character suffers damage from one bullet, Characters with a bonus to defense gain the bonus as a dice roll modifier to the Reflex save.

Running out of Bullets: If the weapon runs out of bullets during a Burst Fire Attack, the Burst Fire Attack ends with the last bullet. If the weapon runs out of bullets during a Suppression Attack, the attack automatically fails to suppress anyone in the target area.

Limited Burst Setting: If the weapon has a limited burst setting (eg: a three-round burst setting), firing a burst expends the number of bullets as per the setting instead of the Rate of Fire listing. Burst Fire with this setting activated cannot be continued between subsequent actions, nor can the weapon perform a Suppression Attack while this setting is active.

Normal: Characters without this feat may perform a Burst Fire Attack with an accumulative negative -2 per shot fired with no maximum. Thus a character without a weapon qualification firing a targeted burst is –6 for the first shot (-4 for no Weapon Qualification plus –2 for not having the Controlled Burst Fire Feat), -8 for the second, -10 for the third and so on. While a character with a weapon qualification is –2 for the first shot, -4 for the second shot, -6 for the third and so on.

Looks good. One question.

How long does the pause have to be in order to reset the -s back to the start when firing a burst?

What I mean is: Since you can get 3 attacks off at -2, -4 and -6 in the first round and then -8, -10 and -12 in the 2nd. Can you take two shots at -2, -4 and not the -6, then do the same thing in the 2nd (and other rounds)?

OK, lets assume character A is a lvl 1 soldier (proficent with his gun, and +1 BAB), his gun is listed as A:3 (Automatic Rate Of Fire 3), and he has the controlled burst fire feat.

He decides to fire a burst from his gun at character B, who is within one range increment (so no range mod).

His attack roll bonuses are +1, -1, -3.

Unfortunatly his dice rolls don't help him and he misses with each shot, so in his next combat round he keeps on prattling away with his gun at character B.

For his first attack action the attack rolls are -5, -5, -5 (because he has the Controlled Burst Fire feat the acumlitive mod will not get above -6, thus with his +1 BAB it maxes out to -5).

With his second shot he manages to hit character B who falls over. He then uses the rest of his turns actions to move which brings him into view of character C.

In his next combat round character A fires a burst at character C, his attack rolls are +1, -1, -3.

Now if character A did not have the Controlld Burst Fire feat, his attack bonuses would be -1, -3, -5 for the first burst. Then -7, -9, -11 for the second burst.

Basicaly you have to let an action pass between burst fire actions to let the mods reset.

So A couldn't do 2 shots at +1, -1 in the first round, and then +1 and -1 in the next as well?

And why are not not in the chat room you Aussie!

No, because the weapon he is using has an automatic rate of fire of 3, thus three shots. And enough time does not lapse between burst fire actions so effectly the fellow is standing there and shooting, runs a bit, shots again.

His first bit of shoot just happens to cross over two combat rounds. Although technicaly two different burst fire attack actions in seperate rounds - that are considered linked because the actions themselves occure straight after one and other.

If Character A had moved, then attacked in his round, then in the next round, moved and attacked. He would then get his three burst fire attack rolls at +1, -1, -3 each time.

Ok! I've never played Mod d20 but the above rules seem ok.

Standard d20 Modern Burst Fire is -4 to the attack, uses 5 bullets from your magazine, and if you successfuly hit it deals 2 extra damage dice.

If you don't have the feat you attack a 10ft x 10ft area, it costs 10 bullets and if you try to attack a spacific target the shots are waisted.

Its nice and simple - too simple, I don't think it reflects automatic weapons correctly.
