Seek N Destroy (SnD) is an Alliance battle mode where you are matched against another Alliance based on strength.
The matchmaking is based on the average level of the top 5 players in your Alliance, which determines your SnD level. This ensures that battles are relatively balanced.
When an Alliance initiates Seek N Destroy, the opponent is automatically selected. The attacking Alliance can only fight opponents within their level range, while the defending Alliance can attack any member of the attacking team.
New Alliances get a 2-week protection period during which they cannot be attacked in this mode. This gives them time to grow stronger before entering competitive battles.
