I'm down in the mine shaft and according to the walkthrough I have there is supposed to be a bottle in one of the two lockers in the room next to the broken projector. The bottle is supposed to be placed in one of the two compressors (that's what the walkthrough calls them) in order to break it. There is nothing in either of the lockers. I have two beer bottles in storage but they do not go on the compressors. Help - don't let me die down here.

I have the latest patch installed.
Any guidance would be greatly appreciated.

Never mind.
I watched the YouTube walkthrough and the bottle is there so either I screwed up somewhere or my installation is hosed.
I'll try again.

Apparently, bottles in this game have to be brown to be able to break.
