i dont know what we canactually do online but my code is 305133605472

http://en.wikipedia.org/wiki/GTA_Chinatown_Warsit says here wifi coop etc and also when u connect to wifi on gta it stays connected in single player so i think its sort of like drop-in, drop-out specific coop missions like on gta4 and deathmatch :-\

I added both of you to my friends list, add me my code is 313723394712

Not really Technical.

doesn't say much , u can only do missions to gether on wireless locally wiwhc spoils it whereas online it's just exploring trading n sharing drugs n places lol will get mine for u soon
