Help in self destructing building...
 

I'm in the self destructing building and where i'm lost at is the part where you go into the second pressure chamber and it's starts counting down to destruction. What i'm i suppose to do, if it counts down to zero i get killed and that room seems completely sealed. I can't seem to shoot my way out or anything. I've looked for switches and stuff before i get in, but i can't seem to find anything.. Is there some sort of secret i'm missing?

Thanks
Ryan

I won't tell you the answer outright (the puzzle is too simple for that http://www.veforums.com/wink.gif), but I'll tell you that the answer involves shooting something...

I just fire the M79 at the glass in the room (be outside the room when you do it)
