Nuke
From the MEGA Wiki
The nuke is what eliminates a city. When the last building in a city is destroyed, a nuke hits it, and that player and their Titan are out of the match.
What sets it off
Every building in the city has to be gone. Damaged buildings don't count until they're destroyed, and killing citizens does nothing toward it.
After the nuke
The ruins are worth 10,000 gold to whoever collects them. The eliminated player can keep watching the match (see Spectating). The last city left wins (see Winning).
