I have been an engineer for about seven years now and I have this habit of noticing tiny technical details in everything whether it is a BIM model or a video game . I was running through the Tower the other day and I realized that the audio for your footsteps is surprisingly deep in this game . If you walk on a metal grate you get that specific hollow clank but if you move onto a solid plating area it shifts to a duller thud . It is one of those intentional details that most people probably ignore while they are rushing to grab bounties but as someone who deals with mechanical systems and material properties all day I really appreciate the work that went into the sound design here .
It is not just a generic footstep sound being pitched up or down either . You can actually hear the difference between thin metal and heavy reinforced concrete structures . I spent way too much time yesterday just walking back and forth near the hangar area testing it out and it is incredibly consistent across different zones . It is this kind of obscure and relevant detail that keeps me immersed in the world even after playing for years . It feels like the developers actually cared about the physics of the environment instead of just slapping a basic sound loop on the character model .
