The tip book I found said you must gather your squad, go to the edge of the map, and click out side of it to exit. Doing this just says "Path Not Found". I can exit via the 'Leave' button, but I dont know if this actually completes the level or not...

Im on the arms warehouse level. The first one in Northern Britian. I have the knocked out German, but I cant leave. What gives?

Please correct me on this if I'm wrong, but in my experience, if the Leave button is green you're basically safe to leave. Just make sure you've collected the clues and you've got the target slung over someone's back. Hit the Leave button and you're good to go. I haven't lost any missions doing this yet and everything seems to proceed normally. It would be a serious PitA to have to physically walk everyone to the edge of a map to leave.

Yeah, you are right. That is how it is done. Crazy... It gave me a confirmation that I did everything right. Thanks for the help.

That was a great level. I had to start it over twice after getting my hero killed. SS is one of those rare games that make it worth while.
