see Halo is the special needs child of all online pc games. The code sucks plain and simple (I LOVE HALO PC OK??!!). And what the one guy said about bungie servers is absolutly correct. Free servers from Homelan that kick ass?? ALRIGHT!! If yoou have any spyware, or antivirus programs running while playing halo pc, they will effect performancecand may block packets. Also your not running a router are u? (please SAY NO!!!)
