Brig

A Brig is a unique class of war machines used by the Fallen. It first made its debut through Insurrection Prime, who was used to invade the Last City and break into the Black Armory for the Kell's Scourge

Later members of the Scourge joined the House of Salvation and shared their innovation for mass production. Brigs feature prominently across Europa and these new models have engine cores similar to Fallen Walkers.

Origin
At some point, the Kell's Scourge stole technology from the Gofannon Forge on Nessus and integrated it with their own Fallen technology by kitbashing a Walker mech and a Prime Servitor together to create the war machine Insurrection Prime.

Assault of the City
After losing the forge on Nessus to the Guardians, the Kell's Scourge launched an incursion into the Last City. While the city was still recovering from the effects of the Red War, the Scourge occupied a desolate section of the city and unleashed Insurrection Prime to breach into the Black Armory's vault; which the Fallen had outfit their militants with its stolen technology and weapons to have superior combat capabilities. In response, the Vanguard dispatched a fireteam to raid the Scourge's occupied territory, secure the vault, and destroy the war machine.

Beyond Light
Following a few years since Insurrection Prime's appearance and rampage, inferior but mass-produced copies of it began appearing under the banner of Eramis, the newly proclaimed Kell of Darkness. Identified as Brigs, they were sourced from remnants of the Kell’s Scourge syndicate who had joined Eramis’s House Salvation. The majority of these war mechs appear to be smaller versions in comparison to Insurrection Prime. The smaller versions of these war machines are labeled Brigs while the much larger variants - similar in size to Insurrection Prime - are labeled Commodores.

Gameplay
Brigs are a dangerous and challenging opponent to face on the battlefield, both with their high durability and arsenal of weapons to hammer Guardians with. They are equipped with the same weapons as the Insurrection Prime; a pair of front-mounted Arc turrets, an arm cannon that fires Void blasts, a retractable launcher to bombard players with volleys of missiles from above and an Annihilation Blaster mounted on the other side, which can deal tremendous Solar damage and can potentially kill a Guardian in a single hit.

They will stride around, firing on players with their Arc turrets while occasionally using either their Void cannon or airstrike missiles, but when they lose a significant portion of their health, their face plate will blow off, exposing their engine core weak point. In this state they will hover stationary in the air while firing repeatedly with their Annihilation Blaster until either they or their target has been killed.
