My cousin brought up his xbox 360 and CoD 4 and 5, and we were going to have a system link 4v4, because the cases said that you could do up to 2-24 on system link, turns out on system link you can only have one person per xbox 360, so unless you have 24 xbox 360's and 24 cod 4's or cod 5's the game fails with System linking action. We were also going to do a big nazi zombie with two people per x-box, that failed to, I am now an anti-fan of Call of Duty, the only way true Multi-Player experience is by playing on X-box Live, now I'd like to compare this to Halo Combat Evolved (#1) You could system link two normal xbox's to create a 4v4. Call of Duty programmers are retarded.
Some of you may think we tried to system link with game 4 and 5, No. We have our own 360 and Cod 4 and 5. We were in the same room, and could get a 1v1 system link, but no 4v4.
