Splinter Cell 3
"...Perhaps the most substantial change is the addition of a new co-operative multiplayer mode. Players will be able to play through what are essentially single-player missions, working through situations that require teamwork. Two of Ubisoft's developers demonstrated how you can pull someone up a wall with a rope, how you can guide someone with your sticky camera view, how you can hold someone by his legs out of a duct while he reaches down to hack a computer, and how you can give each other a leg up to reach higher walls. At one point, one character catapulted his partner high enough to grab a ledge; while his partner dangled there, he then grabbed his ankles and shimmied up his body to get to the ledge. It didn't look very graceful, but in the high-stakes world of international espionage, you do what you have to do, whether it's snapping spines or using your buddy as a ladder."
