The oldest megacorporation in the world. Saburo Arasaka turned his father's company into a world leader in security, then into an arms empire. Arasaka Tower in Corpo Plaza is Arasaka's West Coast headquarters and the most heavily guarded building in the city. Its soldiers and agents are known for their training and loyalty.
On duty you get the Arasaka security uniform: a strict classic black suit, the same for every rank, for women and men alike (a suit jacket with a waistcoat, a white shirt with a black tie, trousers, leather shoes, heeled for women). From rank 2 you also get the Nue duty pistol with its rounds. The uniform goes on over your own clothes and comes off when you go off duty, just like the city services': more on the How factions work page.
