Issue in Overture - Part 3: Steamrunner

[achromicia]

Hey all,

I seriously hope I'm either doing something wrong or there is someway to get past it.

Just past the steam killer floor there is a vent underneath a stairwell which is the obvious path to take. The issue is when I go to the right inside the vent shaft and I find the vent cover to exit with I can't seem to break it at all.

I'm guessing this is what I'm supposed to do as I've even looked at some walkthroughs and this is where it says to go...

Any help would be awesome.

Cheers,

Nick
