Defend the Wonder is a game mode in Age of Empires II. It is a variation of the popular Post-Imperial Age Deathmatch. In Defend the Wonder, Player 1 has a Wonder that must be defended for 250 years. Other players may side with Player 1, but otherwise, they are on a team that tries to punch through the defending Player's fortifications and destroy the Wonder. If the Wonder falls, the attackers win, if it stands, the defender(s) win.
