The thing about those abandoned factories is that designers love to layer them with little Easter eggs. In a 90s point‑and‑click, you’d find a rusty switch that, when pressed, drops a ladder into a secret tunnel, or a broken vending machine that, after you click it enough times, reveals a hidden room. They use the neglect as a canvas—cracked concrete, peeling posters, flickering lights—to signal that something else is lurking. The real mechanics often lie in how the environment reacts to your actions, like the shift in light revealing a hidden map or the way a dust‑covered switch triggers a moving platform. It’s all about giving the player a sense of discovery that feels earned, not just a gimmick. That’s why those gray, forgotten places feel so resonant even today.
