Demolition Expert Trophy in Deponia
A good demolition expert doesn't need a second try.
How to unlock Demolition Expert
In the Village Center area, in the alleyway, is a demolition map. You will need to place three magnets on three specific houses and start the demolition. This needs to be done to progress the story, but doing it correctly the first time is what unlocks this trophy.
Notice the demolition map is laid out like a grid. Place magnets on A4 and A5 (the only two dots on the top row) and one on F6 (the far right spot on the bottom row). Ring the bell next to the map to start the demolition and unlock the trophy.
