Ghostbusters: The Video Game

While on the Times Square mission (If you are looking for the checkpoint to load, it is "Race to the Roof") you will enter a building to avoid Stay Puft. After a short cut scene in an elevator, you will arrive at an architectural firm's office. Enter the office and battle the Stay Puft's dog minions. This is the same room where you collect the architectural model for a cursed artifact. After the battle take the time to destroy everything in the room. Everything. All the desks, cabinets, ceiling fans, partitions, etc. You should accumulate over $10,000 worth of damage. After you've thoroughly hosed the room with your proton pack, leave the room with Ray. Once you leave the office you will unlock this achievement.

fyi, you will need to load the mission "race to the roof", then you are only a few seconds away from the room

On the Times Square mission you will have to race Stay Puft to the top of a building. In a big room where you must fight his flaming minions, destroy everything in sight. All the windows, desks, mirrors, everything. NOTE: You have to leave the room and advance the game to get this.
