Finding a mod

I'm looking for a Half life 2 mod.

Its single player

The start is a cut scene then you go inside a building to face a wave of enemy's. After which you enter a elevator to the elevator level.

I found it a couple of years ago when I downloaded hl2 on pirate bay and I can't find it again. If its out there please help me find it. 

If it helps you had access to many weapons like a psplauncher and sissors. There was a level where it was a room of pillers and a seperate level was all white.
