Teamplay is evidently one of the core elements of Halo, working together with other players or AI allies in combat. On foot, you can attack in pincer movements or have different elements support each other. Specialization like that is encouraged as you gradually master the game. The game's animation and physics have raised eyebrows ever since its debut. Jeeps rock on their suspensions just right, and bounce realistically down a hill when they tip over during a sharp corner.
Flyers zip about and leave little contrails from their engines.
And lest they be forgotten among all the mechanical whatsises, the humans animate perhaps the best of all. While no official sources could confirm the PS2 game's existence, Bungie has said that it's looking into next-generation systems, including both PS2 and Dreamcast. Still, despite the denials, publisher Rockstar has the console rights to Halo, and has said on the record that the company is definitely considering bringing it PlayStation 2. Rockstar has unofficial plans to bring Halo to PS2 in 2001, possibly in online form. We do have the console rights, and I wish I could tell you something, but I can't.
