thomrnh: Hi,
I'm re-playing Overseer and I'm totally stuck, and hope that some kind person can help me out.

I'm in Alcatraz, and have got to the Dungeon.
The HINT (I had to resort to it) said to find and look at the Guard.
I did this, but it didn't tick the hint as completed.

I have opened the 4 vent panels.
I have a gas bomb, which is ready and armed.
I have a gas mask.
I have a Guards Pass card.

I've inspected all the cells on all 4 floors at least 3 times and I can't find anything else to pick up.
I'm assuming i need something to force open the vents and put the gas bomb onto them to knock out the guard.
But I cant find anything to do this.

Can anyone help me please?
Thanks

plumgas: did you get the dirty filter from the glad bag & also the gadget to open the vent. there is a door near the gate that you need to access
