Yes.
Bungie decided to shut off the Halo 2 servers a few months ago. They had it run for several years and it was losing popularity due to Halo 3, and Halo Reach. They finally shut the servers. But don't worry, you can still play on Vista.
Billions of dollars, to cover the cost for hardware, testing, software, marketing, streaming, servers, etc.
no you will have to somehow hack the servers to allow your armor on and then convince the admin to not delete your armor and not perma-ban you
yes it is. it would be announced if they were shutting down the servers.
At this precise moment, it is currently unknown. Halo CE Anniversary will, however, use the original halo's campaign levels, but will use the multiplayer system and indeed servers from Halo: Reach.
Unless you blocked yourself in the first place (in which case, do that, but opposite), you don't.
Install setup files, and update to the newest version.
No because the people who make halo are Microsoft so there is no chance of PS3 Halo.
No, even LAN servers need internet.
Probably never cause bungie has nothing else coming out.
L2 Halo.
im not sure how many they ARE going to make but so far there's halo 1,2,3,4 halo wars, halo ODST, halo: Reach, halo anniversary, and more coming
