Help please when i play call of duty 3 on xbox live it trys to load a game but just says "cannot connect to all players" this happens with any number of players over 3

check playing with this disc on any other Xbox 360 connected to live, ideally the disc should not have problem since the problem you are facing could be with saving or downloading of the specific update required to play game online on xbox live which is mostly related to updated playlists.

If it still does not work, try erasing the saves for this particular game from your Xbox 360 HDD in case you are okay to forego the game progress / XP gained for the offline campaign play.

to enter the code for modern warfare 2 that can be found at the back of the disc case please follow these steps:

1. connect to xbox live
2.play the game
3.there is an option for redeem the code in the game once the game load up

That happens when other people join the party and leave before its done loading and there aren't enough players to play the game. It happens all the time with games like Halo 3 and RainbowSix.

first check your fire wall settings on your comp, then make sure its just halo, if its just halo then it could be the disc.

because its a Xbox live game

as you may already know its probably not your router... check and make sure you have all the XBOX live updates on your 360... the link below should get you started.

I think because it was a BETA. They just wanted feed back, so they can tweak with the COD 5 game. That same thing happen when Halo 3 BETA came out after several week you couldn't play it no more. I have the same problem, ask your online buddies and see if they can get on. Hope that helps.

one would have to come over to figure that one out. try a local friend whos good with these things.

only if the game says you can by a guest profile call of duty 2 lets u do that dont know about tiger woods

Yes you can play 4 players on it. There might be a problem with your router.
