Mex

Mex is a slaver guarding the gate to The Pitt. He will take all the items in your inventory (except the "hidden weapon" you may have received from Werhner and the Worn Slave Outfit you took from the dead slave) and then tell you to enter Downtown. Your things will be returned to you after completing the Hole. All items taken are in a footlocker right behind Faydra.

Weapons
Mex also has an Infiltrator, the new silenced and scoped Assault Rifle featured in The Pitt. He is not the only NPC to wield this weapon, however, as his two guards as well as Gruber in The Hole also wield it. If you plan on completeing the Pitt in Ashurs favour it is suggested you kill Mex and the 2 other slavers at the gate as soon as you get there and steal their infiltrators, when you enter they will be taken from you but you will get them back later in the game, this way you can have 4 infiltrators without the pitt slavers becoming hostile to you.

Glitch/bug
