Bug at chapter 4?

[major]

In Demon Crusher difficulty cheat no function !!! How I can pass through without gas-mask !! I get a key and gasmask - after open the door but gas-mask malfunction !!! I die and die and + many die !!! This is Very irritant fact for you really good game !!!

You need to restart the whole level and play the level as it was intended. When you start the level and gas barrels explode, go back to the starting room and pull the lever. Once the gas is gone, open the doors and continue.

Problem is that you run through the gased area without going back to the starting room, which causes gas mask to stop working, later in the level.

Or you can wait for the patch..
