The Defense Mode is an new Mode, that was improved on September 2013.
In this mode the teams must fight each other, like the mode Team mode, but they must defeat their Monsters that moves in the map, too. The winner is the team with the most Points. Points are Monsterkills + Playerkills. be carefull, the other Team wants to kill his Monsters and you! In a room can 8 players fight each other in this mode.
Yea, the monsters are at the start very weak, but they will be strong at the end! Monsterkills are good for your daily Missions, too. A positive aspect for the farmer.
This Mode was a brilliant idea, which is not so good in the game. The Times are too long and the most people use it to farm
