Tunnels

You head down the right tunnel, and a cold rush of air hits you on the back of the neck. A low hum emanates all around.
Could it be a source of power? A generator? You don't know but continue walking.

At the end of the tunnel a different metal door stands before you, no keypad this time. You try the handle and push open. Surprisingly it isn't that heavy and you almost fall into the next room.

You shut the door behind you and look around. The room is slightly higher than the tunnel behind you. That would explain the non-existent water.
A wooden table sits in the center on a concrete floor, and an incandescent bulb smothered in cobwebs hangs down glowing piss-yellow.
There's an object sitting on the table, and you walk over to get a better look.

It's a black walkie-talkie, but it's off. You pick it up and only see two buttons: What seems to be a power button and the "talk" button.
You suddenly realize that if there's only one of them here, someone else probably has the other walkie-talkie.

When you press the power button a low beep comes out of the device, and then you press the button to speak, but you're shaking nervously.
"Hello? Is...anyone there?"
There's no answer.
"I repeat, is anyone there? I'm stuck down in this strange place and I don't know where I am!"
Suddenly there's static for a few seconds, and a raspy deep voice comes through.

"Someone finally found me, eh? To hell with ya. There's no gettin' outta this place."
The static stops and you press the button again.
"Listen, man, I'm in the same position you are, but if we work together we might be able to do something."

The man replies, "Alright. What's your name?"
"My name's Nick. You?"
"Thomas. I been stuck down 'ere for days. I doubt you'll survive for half as long as I have. But...if ya think you can find a way out, I'll help ya."
"Okay. How much of this place have you been through?"

"I dunno. All I know is there're three levels. I'm on Level 3. Trapped in a room, I barricaded myself in. Yer on Level 1, I'm assumin'. There's a machine powerin' this whole place, but it's deadly power. Energy so powerful it'll rip yer damn face off. Anyway, ya need to get to the control room. I only been there once, too dangerous. But it's imperative ya get there because you need to deactivate door control. That'll give us access to every locked door on every level."

"Including the door with the keypad where I woke up?"
"Eh. I guess yer legitimate after all. Yes. But once ya shut down door control, the whole frickin' place goes nuts."
"How do I get to Level 2?"
"Through the door straight ahead. It'll open up to a platform overlookin' a big sewer system."

You follow Thomas's directions and head through the door.
