High resolution (3840x2160) screenshots of Halo 3 reveal some very nice new game features that the Halo 3 developer team is very excited about. Everything has gotten major graphical redesigns, to ensure extreme realism. There are new weapons, such as spartan beams (the second screenshot shows it quite well), new vehicles like the mongoose (again, in the second screenshot), and new ways of storing weapons. In previous versions of Halo, weapons simply disappeared when not in use. Now, weapons are stored on the players back, side, and belt. There are also new ways of keeping players from going out of bounds. Ideas such as land mines, auto-turrets, and killzones are all being explored by the Halo 3 development team. In the meantime, have a look at the pretty screenshots.
