All right, team, here is the armory. As you can see, we have quite the selection to choose from. No large weapons. If you choose a rifle, it must be something you can fold and conceal in your apparel somehow.
Over there we have rope, knives and sheathes, wall-climbing gear, and various street-fighter paraphernalia such as brass knuckles. These are all period-appropriate.
In this area here we have handguns, compact machine guns, short-barreled shotguns, etc.
And in the back we have more modern weaponry that has been disguised to look like period arms. Laser weapons, shock-wave guns, tasers, heat vision, night vision, and firearms that can shoot around corners have all been modified to look like arms from 1986.
Choose your gear.
