I understand that an ammo explosion will cause additional damage to your mech (unless you utilize CASE).
What I am curious about is how the amount of damage is calculated and distributed.

I have read several posts in this forum that indicate conflicting experiences with this.

For example, is there a difference in damage between carrying one ton of ammo vs a half ton?

And what about the amount of ammo already expended?
If your late in the game and have used all of your ammo, does the slot containing the ammo still explode and how much damage will it do vs a full load of ammo?

When the destroyed component causes damage to spread, is it spread to the front-rear torsos, evenly, or to the center-rear-center evenly?

Confused and sounding like I'm off my meds - - - -

Of course, it is.

For example, ammo explosion of a full ton of AC-20 ammo does 160 points of damage to your 'Mech. Ammo explosion of a half ton of AC-20 ammo does only 80 points of damage to your 'Mech.

No, it can not explode. Imagine it as throwing magazine full of rifle ammo into the fire. (Children, do not try this at home!):
1. Magazine with 30 cartridges does a big explosion.
2. A half-full magazine does much smaller explosion.
3. Empty magazine is just inert metal. It can not explode.

For completeness I would like to mention that Gauss Rifle ammo can not explode, when its ammo slot is critted. However, the critical hit renders all yet unspent Gauss Rifle ammo contained in that slot unusable.

Could you rephrase your question, please?

It is perfectly all right to ask. You can always ask in this section: New Player Help

[Peace2U]

Thank you for your prompt response.
I understand that if the ammo is empty, there is no explosion.
What if there is a small amount of ammo remaining?

To rephrase the earlier question, I would like to know:
a. if leg ammo explodes, does it go to the front of that side torso or to the rear, or is it spread evenly to both front and rear?
b. if a side torso contains ammo and is destroyed, does the ammo explosion go to the front of the center torso or rear center torso, or spread evenly to both front and rear center?
(this question raises concern for mechs with reduced rear armor or internal structure)

These may be very specific questions, but I feel the answers will help while configuring your chassis.
For example, you would not want ammo in the leg or arm of a chassis that utilizes an IS-XL engine if you did not have adequate armor and internals to protect it.

Thanks again for your knowledgeable response.

Peace

asdas if you click that link to mechDB build..
on right side of screen there is "warehouse" text, select 2nd symbol under it from the left, uncheck "mounted weapons" box.
now you should be able to see all ammo explosion values by hovering your mouse over the different ammos.

each shell/missile have it's own damage value and if you have used some of the ammo from that full ton it does less damage.

a & b. ammo explosion goes in Structure.

Case doesn't prevent ammo explosion, it prevents it from spreading in your example a. from leg to sidetorso.

PS. usually ammo explosion values are that high (200-300) that if full ton goes pop and you don't have case, you are dead.
BUT chance of ammo explosion is VERY small.

[Thorqemada]

Afaik and remember an Ammo bin (the specific ammo bin that is put into a certain slot) wont explode if at least half empty.

The overall chance for Ammoexplosion is 10% (on receiving crit damage).

The damage is calculated by the amount of ammunition in that certain ammo bin multiplied with the specific damage value of an individual ammo piece.

Damage Transfer rules apply (no CASE) to transfering damage into other locations.

Damage Transfer means that a location that is already destroyed transfers further received damage at a certain rate (i think its 50%) to adjacent locations.

CASE prevents damage transfer by ammo explosion but the specific location of the ammo explosion is still destroyed.

The damage of an ammo explosion is structural damage and can crit other stored ammo in that location making it a cascading ammo explosion.

The old ammo explosion was the coolest:

Correct.

Then there is a small internal explosion.

It the leg ammo explodes and destroys all the internal structure in that leg, the damage then "flows" to the adjacent section - side torso in this case. It consumes the internal structure there, etc.

Note that we are talking about internal explosions doing 200-300 points of damage, while your 'Mech has 20-30 points of structure in single section.

Internal ammo explosions mean a bad day for a 'Mech and its MechWarrior.

The damage "flows" to the CT internal structure and consumes it. Essentially, it guts your 'Mech from inside.

You can use CASE to contain the internal explosion in the CASEd section. For example, if your arm or leg ammo explodes, CASE in that arm or leg will contain that explosion. Your 'Mech's arm would be destroyed, but the explosion will not reach your 'Mech's side torso.

Inner Sphere CASE takes up one slot and weighs nothing. Clan CASE takes up no slot and weighs nothing (for simplicity, any section of a Clan 'Mech that contains ammo is considered to be CASE-protected by default).

[Mochyn Pupur]

Don't forget that a Gauss weapon itself will explode on a suitable crit hit and do all sorts of damage, if you can, consider CASE in that location to prevent damage spread, the weapon itself is treat as ammo in regards explosions, plus they tend to be super fragile and will blow up far more often than other ballistic ammo.

[Peace2U]

A wealth of knowledge.

Thank you all, Mechwarriors.

One more minor point:

For IS & Clan: AMS ammo does not explode anymore upon crit.

About the gauss rifle exploding...if it is exploding because it is carrying charge, then why do I still need to charge it?

Essentially, it is to balance the fact that Gauss Rifle makes AC-20 obsolete - both in BattleTech and in MechWarrior Online.

So, you can choose from:
a) short-ranged non-explosive AC-20
b ) long-ranged explosive Gauss Rifle

Does anyone know how much damage each gauss rifle does to the internal structure upon exploding? i can't find the values for such a thing anywhere except an outdated wiki.

[w0qj]

Since the placement of the ammunition in your mech is also important, here are more tidbits:

MWO Ammo Usage Order:
http://wiki.mwomercs...p?title=Weapons
http://mwomercs.com/...rsoarmslegshead

1. Center Torso
2. Right Torso
3. Left Torso
4. Left Arm
5. Right Arm
6. Left Leg
7. Right Leg
8. Head

Ammunition in the center torso is always used first, ammunition in the head is always used last. There is a danger of unused ammunition exploding when damaged in combat, see below Internal Explosions for details.

Internal Explosions:
http://wiki.mwomercs...rnal_Explosions

Gauss ammunition does not explode when crit.
AMS ammunition does ot explode anymore.

An ammunition bin has a 10% chance to explode when destroyed, dealing damage as a single hit to its location. The damage depends on the amount of ammunition remaining in the bin. The ammunition within a destroyed bin is lost, whether or not it explodes.

IS gauss rifles have a 90% chance to explode when destroyed and Clan gauss rifles have a 100% chance to explode when destroyed - dealing damage as a single hit to its location. The amount of damage an explosion deals depends on the type of gauss rifle.

Gauss Rifle explosions:

• Light Gauss Rifle (IS) - 16 damage
  
• Gauss Rifle (IS/Clan) - 20 damage
  
• Heavy Gauss Rifle (IS) - 25 damage

It can happen, especially if you have lost a lot of armour and the enemy 'Mech has Machine Guns.

They happen. That's how I wiped out Father Bill's CTF-IM in Solaris way back - I legged him, the ammo explosion took out his entire mech.
