But one improvement I think everyone will notice is our new water. It's refractive, reflective, and can be tuned to create anything from muddy swamp water to a crystal clear Caribbean shoreline. It's fully interactive--meaning characters create very believable ripples and waves as they move around in it.
One of my favorite moments in the game takes place in a flooded area of Twin Falls, Idaho, where around 20 submerged leapers rush the player. All of the leapers are creating ripples, which interact with each other, something that's incredibly hard to program, especially if you want the game to run fast. It's also easy to get distracted by how cool the water looks while you're getting chewed up by the leapers.
We're extremely happy with where R2 is overall. That said, we're confident we'll continue to wring even more out of the PS3 over the next few years.
