Here are the secret achievments for DNF Duel, if someone is interested.
In the face of will
基本的に, you need to complete 5 Stories for any character.
Advocate Of The Gate
Pretty much the same, as the previous.
But now to complete all stories, except for Lost Warrior (he doesn’t have one, it seems)
Gallerist
You need to buy literally everything in the Gallery
All art, 音楽, movies, voices, you get the idea
以上です 100 Illustrations, どの費用がかかりますか 100 それぞれゴールド. それから, Character Voices cost 1,000 and there is one collectible per character. For the BGMs part, you’ll need to buy 15 tracks that cost 500 それぞれ. 最後に, there are only three movies, but they cost 3,000 それぞれゴールド — プラス, you need to complete the Story mode to unlock two of them.
個人的には, I’d recommend using some software that could spawn you ton of money.
Veteran Fighter
300 Online Matches, it does not matter, win/lose, ranked/room.
If you like playing with people you will get if eventually.
そうでない場合 – WELCOME TO THE JUNGLE.
Victorious over Hardships
Defeat the strengthened Lost Warrior in Arcade mode.
基本的には, its an Extra Unlimited version of the Lost Warrior.
Just dont die/lose a single round and Good Luck with that one.
At the End of Wandering
完了 10 matches as Lost Warrior (you need to unlock him first, ofc)
And thats basically it.
And that is all, 皆さん.
I do not see any reason in explaining any other achievment, since they are mostly self-explanatory.
Record some moves in training mode, play there for an hour, complete all combos and challenges for one character (I personally recommend Crusader for this one). Grind a lot of Online, play arcades, story mode, try out every character and so on.
ゲームをお楽しみください, 皆さん, have a nice day.
