Costumes
New costumes can be unlocked for each of your characters by repeatedly beating either Story Mode or Time Attack with that character. You can play through Story Mode on any difficulty to earn new costumes, but if you play through Time Attack, you have to play on the default settings. Of course, some characters (Ein, Gen Fu, Leon, Tengu, and Nicole) can’t be played in Story Mode, so you’ll have to play through in Time Attack mode. You can buy these costumes in Zack’s shop if you prefer.

Hairstyles
Some characters even have different haristyles, which you can select when choosing your figter. When selecting a character and costume, press different buttons (A, X, Y, or Start) which may bring up other options. For example, La Mariposa has a maskless costome if you press Y while selecting her outfit).
System Voices
Each character has their own system voice, which you can use to replace the default system voice in matches from the options menu. To unlock the additional system voices, you need to use them in sparring mode and complete all of their Exercise modes, which will take you through their entire movelist.
Hidden Stages
There are three hidden stages in DOA4.
| Stage | Unlocking Method |
| Biolab Core | Complete Story Mode once with any character. |
| Nassau Station | Unlock Spartan-458 |
| Tatami | Unlock all characters, unlock all system voices. (The Tatami is always available for sparring, even at the beginning of the game.) |
