Pearlescent mech parts are amongst the 6th rarity and does drop from silver, gold and mythical boxes. The designs are unusual. there are:

Sniper rifles: these can Deal massive damage but the further away you go, the more damage it deals! it is best to go back far away and snipe it from a distance. great at long ranged combats, howether the sniper rifles deal alot of damage, it comes with a cost of high weight and takes both bottom left and right slots(hands).

Chainguns: unlike miniguns and gatling gun types, the chaingun attacks TWICE! dealing double damage(50-132x2), with high weight and high damage, it's costs are taking up 2 turns and high heat generation.

Laser discs: Laser discs are powerful weapons that acts as a melee and ranged at the same time. although the weapon range is low, it makes it up for lightweight and higher damage than level 27 bladed weapons.

Legs: although they have a greater movement bonuses: increases the ammount of ammo and rocket cap. and higher damage.

TORGUE WANTS NUKEM TO BE ADDED SO HERE IT IS: THIS WEAPON IS SO BADASS THAT IT CAN DESTROY 6 LAYERS OF HEAT RESISTANCE! AND IT ALSO DESTROYS THE DRONE IN THE PROCESS! LASERS ARE A S**T STICKS!

(Seriously; extreme damage, High rocket cost, heavy knockback. Destroys a drone in a process, making the enemy drone unusable for 3 turns).

Urm, some ideas are tooooo overpowered, like sniper rifles. There are already knockback repair builds, and with a sniper rifle? Oh god, I could already see it. Two blowbacks and a sniper rifle. NIGHTMARES FOR DAYZZZZZZZ

Anyway, there is already a sniper rifle in the game lol

This "sniper rifle" weapon should be renamed to rifle and Nukem is named after Duke nukem and a weapon in borderlands 2.
