Don’t let the fact that Footfall is printed on paper confuse you, this TTRPG is an immersive sim in the vein of Dishonored and Deus Ex. A self described stealth-action RPG, Footfall flourishes by first giving you a florid look into a grimy, horrible industrial world, and then provides you with an expansive suite of mechanics to influence it. It even has a physics system!
