I personaly like to throw halo2 partys and hook up multiple systems.
To do this,the supplies you need are 2 Xboxes(obviously), a Net Gear (or other network device, or a crossover cable) and 2 Cat5 cables to hook up the xboxs to the Net Gear.
When playing Halo2 on two systems its best to have the tvs in different rooms so you and your freinds can't see each others screen (which starts alot of fights when playing.)
First you plug the cat5 cables in the back of the xbox then plug in the other end into the net gear. note:net gear must be plugged in to the wall jack for power
Then you put in halo 2 (the best game ever) and start up the game on both systems. There is a system link option on the menu in Halo2 that you have to turn on.
If there is more than one person per system have them all log on then hit accept. Have one system create a game then the other system can join the game.
