Darkstalkers Chronicle: The Chaos Tower, known as Vampire Chronicle The Chaos Tower in Japan, is a Capcom fighting game for the PlayStation Portable. It was released on December 12, 2004 alongside the PSP at launch in Japan, and in North America on March 24, 2005, a week before the North American PSP launch.
It is a port of the Japan-only Dreamcast game Vampire Chronicle for Matching Service, which in turn is a version of Vampire Savior that allows players to choose their fighting style from all five Darkstalkers arcade games (DarkStalkers, Night Warriors, Vampire Savior and the Japan-only Vampire Savior 2 and Vampire Hunter 2). It has all the characters from prior installments of the series. The game includes all the endings and moves from the games: Darkstalkers, Night Warriors: Darkstalkers' Revenge, and Vampire Savior. The complete soundtracks from all three games are also selectable based on play style. However, the levels, selection screen and supposed endings are all from Vampire Savior 2.
A major source of confusion is whether the game has an infrastructure mode, which allows players to play each over the internet. Sony lists it as an infrastructure game, and the back of the case says it has infrastructure mode but, in the game itself only has ad-hoc mode.
