On the southern most part of the map, there will be a store with the front door open just enough for you to fit in, its doors are blue and has a giant yellow lizard/dino above it.
Once inside, in the very back of the store there is a model city on a table. Use the boxes on the right of that table to get some hight. Once on the table with the model city, destroy it all with your trigger buttons! Once the last piece is broken the achievement will pop.
