It was like a fiend from hell. Flames all around it, all over it's body and yet it laughed as the boosters screamed and burnt around it.
As a flame shot out from it's arm to engulf yet another booster I realized that it was a 'borg.
Then it saw me.
I'd rather not go into what happened next but the synthskin I had to get is a constant reminder of that thing and I'll never forget the screams of those boosters.
And if I ever find the sick individual who thought up this thing I'll bloody kill him.
The worst thing though, is that the image of those boosters as they died is imprinted on my brain.

I still wake up screaming some nights.

This armor is more suited to a full-body conversion than an add-on to a full 'borg but can be obtained both ways (although some consider the 'borg to be too 'specialized' for general street work, hence the armor only version is more popular).

The Solar Combat Armor is a specially constructed armor coating to the 'borg which is made specially heat resistant and fire resistant (hence flamethrower immune). The Armor affords no extra protection in Stopping Power but the effect of a flaming borg on opponents has been found to have a paralyzing effect on them. But the major drawback is that any gear being carried by this 'borg has to be specially treated so it does not burn up once the armor is activated.
One of the things this thing is very good at doing is getting the attention of any thermographic and infrared sensors when it is activated as well as distorting the image any thermal optics the 'borg has. The recommended maximum use time is 10 minutes (for cooling and reducing the number of fires started) with a cooldown period of 20 minutes (less if cooling system installed) and the fuel supply is enough for over half an hour (45 minutes).
There is only one known currently in existence and has been used for assassination and booster 'control' in the Night City region. But it assumed that a number of them are being constructed.

The armor system takes one option space in each limb (for the full body flame) (and is not suggested for Gemini or Battle Angel 'borgs) as well as 1 space in the torso and an ammo hopper dedicated to the system (although a flamethrower can be linked to the hopper). A cooling system can be installed in the torso (1 option space) which reduces the cool down time by half.
The flame system takes 2 combat rounds to be activated (ie it will flame up the round after you decide to start it) and 2 to deactivate (ie 4 rounds of flame minimum)
Lastly a word of warning. If the borgs armor is penetrated there is a 50% chance that the routing system to the flame points will be breached and the borg will become an instant fireball (but won't be destroyed) and any other internal options in that limb will be destroyed (or otherwise damaged and will have to be replaced) the flame can be turned off when this happens but it will take 2 combat rounds for the flames to die down and the system cannot be used again until repaired.

Cost: 10,000 (armor add-on, borg price below)
HC: 1D6

Coolant System: 5,000 HC: 4

Note: Any clothing and gear on the borg must be fire resistant or be burned up.

Special Note: Although the 10 minute recommendation is made for flame use the recommendation is made more so the 'borg doesn't burn down the city (town, building). 15 minutes is the actual limit and the cooling system makes the limit unnecessary
