Completion bonus
Successfully complete the game to unlock the parody mode. Parody mode replaces the original text with joke dialogue. Note: This is only available in the Japanese version.

Easier game
It is much easier if you have a Wavemaster in your party, whether it is Elk, Wiseman, or someone else; and also have a heavy blade person. This helps very much. Also keep your other members leveled up with you because you have to use them at times.

Dvd Secrets
The DVD that is included with the game has a secret section. It reveals secrets in the game. Enter the 'Data' menu and highlight the '.hack Pro Trailers' option. Press Right to highlight a circular icon. Press X or Enter to view the secrets.

Defeating Goblins
Have some Wood magic equipped. Start the match, wait until the Goblin runs, then sits still for a moment. Then, use the magic. Goblins are all weak against Wood; two shots will kill them.

Secret Keywords
During the last episode of Liminality, the keywords ''Sickened Imprisoned Fallen Angel'' flash across the screen in Japanese very briefly.
