Just for you Teon players, here is the link for downloading C4 full client
ftp://l2clientdownload.lineage2.com/Chronicle04/L2_C4_Installer.zip
It cannot be found on the official download section.... until tomorrow, but now you have it "unofficial" so start your download now and get a head start and avoid "download-bottleneck" when everybody wants to DL C4 full at the same time.
NOTE : Remember NOT to install and update until all server goes C4, or else you migth update the C4 full cient back to C3 :(
good luck :)
