Attackers: Must complete all objectives to win match. e.g. 1. Infiltrate 2. Plant bombs 3. Secure "Flag" and deliver to pick up point.
Defenders: Ensure the enemy does not breach and steal the "Flag". If "Flag" is stolen, prevent the enemy from delivering it to pick up zone. Defenders get 1:00 minute to prepare defences e.g. Claymores and C4.
