That Tunnel Multiplayer Level Mod for Dark Forces II: Jedi Knight

[KyleKatarn1995]

Hello, I would like someone to help me out on this one thing that I've been looking for. It's this one Multiplayer Mod made for Dark Forces II: Jedi Knight, it involves the player having to fall through a long pipe that almost plays like in the Fuel Station level where Kyle goes down through a tunnel. And it haves that Heavy Metal music that plays in the background as your player falls until you reach to the bottom and score a point. What's that Multiplayer Level called?
