poor sequal, bad story line, not long enough, new features are nice though. Lets face it, the original halo rocke
halo 2 includes some nice areas, it made up for most of its mistakes with the playing as the arbitar, but even that got boring after awhile.
I liked how they made it more realistic, vehicles lost parts and then blew up.
and let me clarify, if you are in the vehicle IT WILL NOT BLOW UP UNTIL YOU DIE!!! just letting some doubtful people out there know. This means that trying to blow up the vehicle doesn't work, you are going to have to aim at the person himself.
Even though the campaign mode is alright the true gameplay comes in on multiplayer. test your skills on somebody who doesn't have artificial intelligence. Gain experience and then try legendary, this is the ultimate prize, and if your a veteran to halo; halo 2 legendary has been kicked up a notch. (several notches actually) No more barging in with a pistol and winning, you had better hang back, toss a few grenades, kill off the stupids in the group.
New features: good ones: new weapons, new creatures, more complex levels, better A.I., scope on your HUD, AND AN ACTUAL BOSS FIGHT AT THE END!!! bad ones: some downgraded weapons, shorter campaign, some extremely easy levels even on legendary, not enough boss fights in either game.
