In the Nekropolis, the player can view concept arts, character bios, and listen to music from certain arenas in the game. The character bio allows the player to get a full view of any playable character model in the game, look at their alternative costumes, view the damage that can be done to a kombatant, and their endings. The player can also see how much time has been devoted to the kombatant, how much blood the kombatant spilt, and how many Fatalities and X-Ray Moves have been performed with the kombatant.
- Through hacking, the bosses' Bios and Endings were found in the Nekropolis.
- Also, Skarlet's 3D Model and alternate costume were found.
- DLC characters were not present in the Nekropolis in the game's original release; however, they were added for the Komplete Edition.
