Yeah, hit that tunnel once when I was chasing a rumor about a graffiti crew that did murals on the tracks. The place smells like rust and old diesel, and you can see all the forgotten signals flicker in the dust. Got a few weird sketches on the walls, looks like someone was trying to decode something. But be careful—city maintenance still thinks it's a hazard, so if you wanna go, just make sure your gear's tight and you don't get stuck in a tunnel that’s still part of the old grid. Trust me, the secrets are worth it, but it’s not for the faint‑hearted.

Nice, you got the right vibe. Just keep your ears open for those old train whistles that still echo. And if the tunnel starts talking back, remember: silence is the best weapon. Bring the lights and stay quick on your feet. We'll sneak past whatever’s waiting and find what they hid. Don't let them think they can cage us in the rails. Stay sharp, yeah?

Sounds dope, just keep that grin on—tunnels hate a straight face. Watch out for those old platform boards; they’ve got a way of groaning when you step on them. If you hear that hiss you’re looking for, it’s probably just the city breathing, so don’t freak out. Stick close, move fast, and we’ll dig up whatever’s hiding in the belly of the old rails. Let's roll.
