Zones are specific, blue hi-lighted locations the Red Team must capture in Assault (Mode). Blue Team, on the other hand, must defend these Zones. A single red team member must stay in the zone for five seconds without dying to capture it. There are many assault maps but all of them have around 4-7 zones, and Red Team needs to capture every single one of them before the match ends. If Blue Team prevents the Red Team from capturing the last zone, Blue Team would win the match.
Capturing a Zone would allow the person who capture it 50 points.
