Smash
From the MEGA Wiki
Smash is a seismic slam. Press 
in Siege View and your Titan sends a shockwave through every nearby building.
Usage
Smash is the move for taking down several buildings at once. A city is only eliminated when all of its buildings are destroyed (see Nuke), and rival buildings destroyed by your Titan count toward Making an Entrance and Demolition Crew.
