Drake's Deception's cruise-ship level is the manifestation of several of those possibilities: Nathan Drake on the deck of a vast boat, reacting dynamically to its movements, which are in turn dynamic reactions to the movements of the roiling, storm-lashed ocean. The deck is scattered with physics objects that slip and slide across its surface. There are secondary bodies of water on the ship itself that move independently from the surrounding ocean. At first sight, it takes the brain a few minutes to process what Naughty Dog has achieved.
"That level was designed by my friend of co-lead designer Jacob Minkoff, who told me last week that when he came up with the idea for the cruise ship and when we pulled together a group of programmers and technical artists to pitch the idea to them, they initially looked at him as though he'd gone stark raving mad," says Lemarchand.
"Perhaps he had! You have to be seized by a little bit of madness to be so audacious as to suggest that in 2009 - when he first came up with the idea - that there's a ship floating around on a virtual ocean whose hold would then be compromised and which would flood with water which would cause the ship to tip onto its side and begin to sink."
"Of course, we have to run that dynamic water system inside the ship as well as around it, and Jacob says - and I think this is to his very great credit - that having looked at him like he was mad, the programmers then proceeded to talk together for 20 minutes and came back to him and said, 'All right, let's go for it.'"
"They committed to do it and they did do it. It's amazing. I can say this because it's not my level, but I think it's a landmark."
