Bungie have spoken a little about the controls on Halo 3, also revealing that the iconic warthog is back, and under the controls of significantly upgraded AI marines.
There’s no huge difference to the control system, just an attempt at sorting out the issues that some had mentioned playing older Halo games on the Xbox.
There’ll still be the option to play with the classic controls, and it’ll also be possible to reverse the controls to allow left-handed players to use the appropriate analogue stick.
The Warthog is apparently set to be a "super-deluxe killing machine", as the AI of the marine has been improved dramatically.
"First off, beeping the horn seems to bring any nearby Marine running (although they will come based on suitability for the task at hand - more on that in a future update) and hopping straight into the gunner turret."
"This has two effects on the gameplay - one is that it makes the Hog feel more like a weapon when you're driving, and the second is that it makes you want to cruise around bigger battle areas playing mop-up, whereas previously the temptation might have been to get the heck out of dodge. And by heck, I mean hell."
"The AI still has ages of tuning left to go, and the bad news is that if your AI gunner is too good, he’ll be dumbed-down to make the game more balanced. That said, the scale and ferocity of the current encounters mean that you were going to need more capable AI anyway."
