i believe he means where to get a serial code to play l2 on officail server.. and yes u have to pay for it... u can do it directly by going to
and make an account there its totally legit ... that is the official site for ncsoft... and all of their pay to play games can be activated from there...
just make an account and buy a serial code for 12€ per month... its not cheap, but its also not expensive... so i believe u can get by.... there are also private servers that are fre... thats just in case u do not wish to play on the official server...
cheers, ch34t aka asc3nd3d - player on both official server and private servers... ^^
