Have you spotted the GMan out of the corner of your eye yet...he's around...watching!

I'm about 2/3rds of the way through and I've seen him a couple of times.

PS. Here's how to get Steam to work offline:

Yes, spotted him plenty of times in the distance. In a lot of the buildings where there are tv monitors, you'll sometimes see him in those when you first enter as well - just like in the first one.

All very well done!

LOL

Spotted him last night, gave chase, but funnily enough vanished before I got to him, was near the end of the boat bit
