Step 1. Go to Multiplier and select Private Match,
Step 2. From there Post a thread here or any gaming site with somthing like this.

Step 3. After you have 8-12 people in your lobby depending on your type of boost, invite 4-6 people into a party and kick them.
Step 4. Now you have 6-4 people in your private match -> Switch lobbies to Player match and search for your game you wish to boost , lets use Team Tatical . It could take some time getting your own lobby but after you do just invite your party to the game so you have all your boosters with you wait for the lobby to start,
Step 5. Domination -> Basic way is get everyone to take turns captureing "B" , but a faster way is 6 people spit into 3 groups of 2 and take turns capturing all 3 bases getting 15k xp per 10 mins [150k xp per hr]
Step 6. Demolition -> 2 groups of people from each team plan the bomb\Defuse [Repeat] While other 4 people on each team get head shots using Tactical In.
Step 7. Repeat the process!
