I was just watching the playthrough video and it seems my game is bugged the cranes act like they don't have any power. I did not see any way to activate them. I thought maybe it was because the generators were getting blown up, but there are so many Russians that is impossible to avoid. Even If I run first thing to the crane controls they don't work.

I really want to play the Jungle level since it is probably like the beginning of Raiders of the Lost Ark.
