Welcome to the next chapter in the Double Dragon series! Who’s ready to jump, kick, and punch their way through the 12 missions & 100 floors in the tower to 100% DD IV?! That’s all it takes to perfect this game, with the catch being that you have to beat the game numerous times using different characters. The achievements themselves are pretty straightforward, but this guide is to help with understanding and tips/tricks along the way that I learned by playing through this amazing game. I found that having a friend to run this game cooperatively makes 100%ing this game a lot quicker/easier.

Clear all 12 missions using Billy.

The first step is to go through the missions to unlock “Complete Mission 6” achievement, “Complete Mission 8” achievement, and “Complete All Missions” achievements. After completing the game the first time, it will unlock Tower Mode to be selected in the main menu. A good thing to note is, if you run out of lives you can hit the start button to continue with more lives so that should take off some of the pressure.


GO_TO_JAPAN – Complete Mission 6.



OKADA_TOWER – Complete Mission 8.



STORY_CLEAR – Complete all Missions.



Tip: One suggestion I have is to try not to waste lives on the platforming levels, mission 12 throws a lot of different enemies at you so you’ll want to have a few lives left for a cushion.

Fight through tower mode to unlock Mysterious Warrior at floor 40, then use him to floor 100!

There are six achievements associated with tower mode itself, while also tower mode is the way to unlock characters to be played in story mode & tower mode. You unlock achievements in the tower after clearing the 10th, 20th, 30th, 40th, 50th, and 100th floors. By the time you get to floor 30 in the tower, you have unlocked all the characters needed to do all the story missions except for one, the Mysterious Warrior. He is unlocked after clearing level 40 and he is the character I used to clear the 100th floor in tower mode. Double Dragon 1 Jimmy Lee (Billy’s brother) is unlocked after clearing level 35, but he doesn’t have any achievement associated with him for some reason. ☹


G.O.D._10F – Clear the 10th floor.



G.O.D._20F – Clear the 20th floor.



G.O.D._30F – Clear the 30th floor.



G.O.D._40F – Clear the 40th floor.



G.O.D._50F – Clear the 50th floor.



G.O.D._MASTER – Clear the 100th floor.



Tip: I would use a friend to co-op your way up to floor 40 if your having trouble, unlock the Mysterious Warrior, and then co-oping your way up to level 100 using two Mysterious Warriors since he is the most power character in the game. The levels with Casey/Shannon (girls with guns) are the most dangerous because they can do a ton of damage, so watch out for them.

Complete all Missions using various characters.

This is the grindy-ish part of the guide if you’re wanting to 100% this game. Like I said above, it cuts down playtime dramatically if you have a friend to do runs with. You unlock the character achievements with the character you’re playing as, as well as the one your friend plays as. Playing through the game solo, you would have to beat it 20 times to get all achievements but it can cut the time in about half with a friend playing too. Be sure to use each character's specials!

THE_GENERALIST – Complete all Missions with many characters.



Tip: I want to note that platforming with some of the characters can be tricky because of their “jumping” style….it helped me to watch someone playing through the stages as Ranzou to get the timing and landing spots of his jumps! Using a running jump is recommended. I’ll link the video of someone playing below. At 25:29 he executes the long jumps on the platforming stage.
