Stop using fissics and logic, that has no place here. (IMG:style_emoticons/default/wobble.gif)

Besides, all of them has GV4 and heavy barrel so all he needs is a good backpack for all the belt ammo to give him a counterweight.

Let's look at the same character with 30 fingertip Monowhips instead...

Monowhip is reach 2 ^^

Cant you read - he's using 30, not 2. (IMG:style_emoticons/default/grinbig.gif)

One word: Rollerblades.

heck, with that firepower he could literally walk on air if he aimed down!

ok, lets add some things here.

12 M249: 10KG each fully loaded with 100 rounds.

That's 120 kilogram.

Fully laden troll with clothing and armor would be around 270-300 kilograms if we go by the size of Andre the Giant who weighted 270 kilograms.

Then we add 100 extra rounds per gun in a backpack for the belt rounds. That's 2,5 kilograms per gun, so 25kg.

Total weight is 415 kilograms.

Im sorry, but recoil alone will not move 4/5 of half a tonne.

The Troll will weight more around 360-380 Kilo by Itself ( 300-330 Kilo naked & Armor & Equipment)
Plus 120 Kilos for the 6 LMGs
(Which are Ingram White Knight and Fully Recoil compensated (IMG:style_emoticons/default/wink.gif) )

So its Half a Ton (IMG:style_emoticons/default/rotate.gif) all in all

with a very Heavy Dance
Medicineman

How much weight do the cyberarms and milspec armour add?

(IMG:style_emoticons/default/biggrin.gif) Okay, I dramatically underestimated the mass of our Troll projectile. SR4A says 300kg is a common weight, so, tacking on 150-200kg for guns ammo, and armor (Like he needs it; any bullet is going to hit his ammo belts anyhow... (IMG:style_emoticons/default/wink.gif) ) he masses in at just shy of half a metric ton, or around 34 slugs. Now it's true that he won't slide if he's wearing runflats on dry concrete; he will, of course, flip over, but we're neglecting that failure mode for the sake of awesomeness.

However, lets assume this Mr. AwesomeDakkaSquared is living in Seattle. Where dry pavement is about as common as honest Lone Star cops. Then even in runflats (which I keep using 'cause tires really do have a lot of friction with concrete.) you're look at a friction coefficient of mu=0.3. Or, only being able to resist around 330 lbs out of your 640 lb recoil.

Now, admittedly, all that mass is going to make you accelerate more slowly across the wet pavement. Your trogectile's acceleration is only going to be around 2.75 m/s^2, which means it'll take it a whole nine seconds to reach our target 55 mph. At which, the trogck now has only 150 kJ of energy, or roughly that of a small CAR running at highway speeds...

Even more effective, no? Just hope he doesn't damage too many of his light machin^W^W propulsion equipment in the crash...

Edit: Oh, and just in case you were wondering how much spare ammo he needs to cart around to be stable (for some, ill-defined usage of that word) on wet concrete, it works out to 19000 rounds of ammo. Which will, of course, only hold him still until he actually starts firing his lead downrange, at which point his weight decreases steadily as he accelerates backwards... And it takes him about 48 seconds to run out of ammo completely, by which time he'll be going, oh, around 150 mph. At which point we should really start paying attention to air resistance... a Very Fast and Heavy Dance.

What about bracing then? And please, stop using physics and LOGIC here.

The question is how much force is reflected back on from the firing start until a 20 round burst is fired. We might as well add how much force is actually applied for that combat ACTION.

With Synaptic II he has 3 actions per combat turn where he uses a complex action to fire 20 rounds per gun during 1 second.

It wont be enough TIME to flip over or accelerate backwards.

this reminds me of another broken area, saw a troll roll 50+ dice to resist damage. he had a 40 armor, and an overall +13 body dice. no, he was not encumbered rule wise. he also had a reaction of 8 lol. so all in all a total of 60 dice tops, at a -1 ap. O.o how do you hurt that with normal dakka. not to menthin about 16 stun modifier boxes and either 19 or 20 physical con boxes. made out of chummer...

How do you hurt him with normal dakka? use more. I'm thinking multiple miniguns firing full auto more...

This is why i prefer SR3. Ok, we have a few custom adept powers that functions similar to Orthoskin so he has 15 damage resist and a total of 12 armor.

He can still be killed when something has (D) damage level and the TN is above 2+ because ID he takes a (S) damage it's 6 boxes of damage regardless.

SR4 system is simply a number of Dice which makes the threat level of even a heavy pistol miniscule, a weapon that CAN kill a troll if handled properly but is almost impossible to kill a troll with in SR4.

the guy survived and walked away from basically the equivalent of a tank round . (yes he was an aug. adept.) and my bad was only 11 body. plus he had a straight up -1 damage red. he was not the best shot but.. he doesn't need to be lol. but yes, perhaps multiple miniguns firing APDS or EX/ex. ammo narrow burst could force him back lol.

Oh, I thought you meant normal ammo.
Holdout pistol with capsule rounds full of fun nasty stuff will do the job. Pepper punch can probably cut it. Breathtaker grenades are also nice. If he's running a chem seal then injection darts would do the job, and if he's shielded from that as well (Milspec armour springs to mind) then a HMG with anti-tank rounds (from that book) might cut it.
Of course, if he's running a chem seal then just get your hacker to take control and purge his air supply before unleashing the breathtaker/nausea gas. (IMG:style_emoticons/default/smile.gif)

SnS ammo, broken ammo is SnS ammo. lol

I stayed away from that on purpose (IMG:style_emoticons/default/smile.gif)

In SR3 my troll gets...annoyed by burst SMG's and worried by LMG's on full auto. He took a full auto 10 round to the chest and then told then rigger to shoot a great dragon ATM at the garage opening where he was standing to take out the multiple red samurais and cybermonster - he could take the edge of the blast, the samurai's would not.

In SR4 he would not even CARE about the LMG if I made him right.

Hey! I thought specializing was a GOOD thing! I just took bod, str, rea, cha, int, and agi as dumpstats at chargen. I mean, that and my technical knowledge skill in Physics at 6 gives me a DP of 13. What am I supposed to use here? (IMG:style_emoticons/default/grinbig.gif)

Anyway, if, for some reason, Sir Dakka was happy with a single initiative pass of dakka, he would still receive 640 lbs of force. Yes, for only one second, but imagine getting hit in the chest with a 16 lb sledgehammer. Travelling at 21 ft/s. THAT is what Sir Dakka is feeling. Whether he manages to recover his balance or not, I think it counts as a staggering blow.

But I can't imagine why he would settle for one pass, when he could burn through 19000 rounds of ammo, AND escape to the next county on roller blades in 45 seconds. Really now, be reasonable.

adept troll with miltech heacvy armor ballistic shield, full body suit and PPC anyone?

So, unless bracing against a wall we should do a knockdown test while anything in front of him automatically becomes swiss cheese and not allowed to dodge - after all, 24 dodge tests will fail as their reaction is dropped by each.

Gonna be expensive with APDS ammo...

Perhaps we should use FA shotguns instead with Shot rounds...

Custom gear to get it shorter. Essentially, buy one get one. With the troll reach it comes out to two at the end of the day.

Using your numbers plus what has been provided by others.

Muzzle Velocity : 900m/s
Bullet Weight : 0.063kg
x12 M249 Weight : 120kg
Troll Weight : 370kg

The force of the firing weapons is 900*0.063*12 = 680.4. Divide that by 490 and you have a movement of the troll of ~1.3m/s assuming all 12 weapons are firing simultaneously and we're ignoring other elements like recoil compensation, bracing, or various other effects.

Now entertain the idea that Mr Dakka got tired of zooming around town and decided to get weapons where the main source of dakka wasn't kinetic propulsion... Like say a grenade launcher (it's not the fomp that kills you its the boom!), obviously the propulsion of a grenade would require way less force!
So how much Fomp(assuming it was propelled to a distance where it didn't blow his face off) would it require to get our friend skiing again? (IMG:style_emoticons/default/biggrin.gif)

Now that I think about it... If Mr Dakka had the talents of the before mentioned sponge monsters, maybe he could explode in his face.

Also railguns, magnetic acceleration does a thing or too to reduce recoil no?

yeah that troll could be taken out by an Adept Master Sniper using SnS rounds pretty quickly...1/2 armor sucks for a troll who is all about the Armor

Better yet...Punch Master adept using Sonic elemental fists....no armor counts, that 40 armor is useless against something that bypasses all armor, beyond that the punch master just has to get pas the 11 body vs his likely 15ish dice to hit, add in a Called shot to increase damage....looking at easily 15+nets to soak with 11 dice.

the troll also was very competent in useing a combat axe. so dont forget the defending skills.
