The Ruined City is a location in many Dragon Ball Z video games. It is a city that was destroyed, except for a small area that survived a bit.
There are large buildings and a few capsule buildings in the Budokai Tenkaichi series. In the Raging Blast games, Dragon Ball Z: Ultimate Tenkaichi, Dragon Ball Z For Kinect, and Dragon Ball: Xenoverse are towers that looks similar to Korin Tower, but much smaller. A damaged bridge can be entered, unlike in Budokai Tenkaichi 2 and Budokai Tenkaichi 3 where the bridge is just outside the arena. In the Budokai Tenkaichi series, outside the arena is normal buildings completely destroyed.
The ruined city appears as battle stage in several other fighting games, such as Dragon Ball Z: Ultimate Battle 22, Dragon Ball Z: Shin Butōden, Dragon Ball Z: Legendary Super Warriors, Dragon Ball Z: Supersonic Warriors 2 (as an "alternate" version of West City), Dragon Ball Z: Budokai 3, Dragon Ball Kai: Ultimate Butōden, Dragon Ball Heroes, and Dragon Ball Z: Battle of Z.
In Dragon Ball Z: Attack of the Saiyans, the East City Ruins can be visited after wishing to access a new area using Mr. Popo's Dragon Balls; enemies encountered here are Someone's Robot, Experiment #7, Experiment #9, Failed Experiment, Mad Scientist, and all the types of Saibamen featured in the game.
