The Gotham Gold Reserves Building, (known as' Gotham Bullion Fortress in the DS versions)' is a massive bank/vault compound where most of Gotham's gold is stored. It is located on an island not far from Gotham City, and is constantly under heavy guard by Security Guards, Police officers S.W.A.T teams and a unique Defence Robot.
After escaping from Arkham Asylum, the Riddler set up a plot to rob the Gotham Gold Reserves. First. he and Clayface infiltrated Gotham City Bank to steal a gold key that would allow him to later access the gold vault. With the key in his possession, the Riddler and Mr. Freeze headed to Freeze's old factory to acquire the Super Freeze Ray. Once again successful, the Riddler next met up with Poison Ivy to retrieve vine seeds from the Botanic Gardens. In the final robbery, the Riddler and Two-Face broke into Wayne Industries to make off with the Super Laser. Clayface, Mr. Freeze, and Poison Ivy were all distracted during their quests, and abandoned Two-Face and the Riddler. Using the Super Freeze Ray to create an icy bridge from a shoreline to the island, Two-Face and Riddler then used the mutant vine seeds to ascend up to the compound. The Super Laser, however, failed to have the firepower to blast open the Reserves' main gate and was blown to bits by its own blast. However, the criminal duo managed to still infiltrate the Gold Reserves, and fought past heavy security to the Main Gold Vault.
The Gotham City Gold reserves has two appearences based on what platform it appears in. On the console versions, it appears as a large black, fortress-like compund with searchlights contionusly watching the surroundings. A large tower can be seen protuding from the main compound, which towers above the whole structure. On the DS version, the Gold resrves (labeled as "Gotham Bullion Fortress") appears as a large square buildings with a large golden dollar mark being visible on the side. The searchlights are still present but the rest of the building is completely rewamped.
