Does any one have an idea how to climb on the roof of train station, Paris zone 1?
I was able to climb to the top of the roof of the train station by going around to the side of the building where there are no guards able to walk by. you will see the orange awnings (or whatever you call them)and as you face the building you have to jump up to reach the ledges that will enable you to climb to the top of the roof. It will look like there is nothing to grab onto, but there is. Also, look for the yellow lights that other people have posted about using the yellow lights to show the way up to the scenic spots. You will be able to kill the 2 guards (4 guards total as there are 2 AA guns). Going back down from the roof is the same as going up.
If I knew how to create a video for you I would. I hope this helps you.
