Netmarble Games and NCSOFT started the service of the Japanes version Lineage 2 Revolution. You can download it for iOS and Android and you can pre-register for it until today 23:59. It should be noted that you can start to play with the game on August 23, 2017 from 12:00 BUT yes, you can download it already.
Another thing about the download and the install. The installation is requires active WiFi connection because of the large file size.
