Arcade games have long been a hub for cutting-edge technology, and one of the most intriguing advancements is the integration of scent or olfactory feedback. This innovative approach enhances immersion, creating a multi-sensory experience that goes beyond visuals and sound.

One standout example is *Scent of Battle*, a fighting game that releases distinct aromas like sweat, smoke, or even floral scents depending on the in-game action. Another creative use is in horror-themed arcades, where musty, damp, or metallic smells heighten tension and fear. Racing games have also adopted scent technology, simulating the smell of burning rubber or gasoline to amplify realism.

Beyond entertainment, scent feedback is being explored for therapeutic arcade games, using calming fragrances to reduce stress. While still niche, these innovations showcase the potential of olfactory technology to redefine gaming experiences. As developers experiment further, the future of arcade games promises to be as aromatic as it is thrilling.
