Splinter Cell Double Agent Easter Egg - Ubisoft Street Address on a Construction Crane

At the very end of the Ellsworth level after Sam and Jamie use the "dynamic hoist" manuever to get up and over the large hole in the wall you'll need to hesitate before jumping into the dirt and subsequently the tubing that provides the escape route. While up here take a look around the border just over the construction fence there. You'll see a crane with the terms "Pericopilar" on it, obviously a play on Catapiller - a very well known manufacturer of construction vehicles. The "Perico" aspect actually refers to the physical address of Ubisoft's United States headquarters. 249 Perico Avenue - just a neat little bit there.
