Look at these people looking up chemistry topics on Wikipedia and then spouting it out like they know what they are talking about, ignoring the fact that their points are completely irrelevant to what Bungie showed us in that .gif animation and will still be completely irrelevant even when applied to other affects! Korn, what I'm saying is that it looks worse than water they've had in the past. A flat bunch of tris bobbing around does not look as much like water as a cubemap with some well-designed effects. Yes, I am well aware of the computations required, and I'm not saying that I must have RTR in the water. What I'm saying is that they parade this overhauled engine like it's something genuinely impressive, and what they've demoed is less impressive than what a six year old engine can do, in it's original release state no less.

And technically, you could have been able to hide under water with previous effects. Just have a system that checks if part of your avatar is visible over the substance, and if not, then you are invisible to the AI...similar to Assassins Creed's "blending." Again, this bobbing mass of tris is irrelevant.

@sdavis117: I agree. It feels like this is becoming Unreal Tournament: Halo Edition as opposed to another installment in the series. I dunno about you guys, but I hardly play multiplayer and I buy the game for its campaign and story. Unless it has a bang-up single-player, I'm going to be sorely disappointed, again.
