–Ingame description

Overview

Weapon Lockers are seen through out Nathaniel Renko's travel through the game. Here, a player can upgrade any of their currently discovered Weapons and buy ammunition for them by spending Weapon Tech and E99 Tech respectively. The player can also swap out their weapons here if they find the one they have currently does not fit the players need.

A weapon is considered discovered and added to the Weapon Locker when it it picked up for the first time, with the exception of the Seeker Rifle and RLS-7, as these are considered as special weapons, and do not use either of the players two weapon slots.
