Experience per Match

3 head shots a round,
one plant, or defuse per round
3-4 extra kills a match,
19,000 exp every round after the second,

Therefore, on kills and plants alone you get 31,000 experience. With all kill streaks executed perfectly you can get another 114,000 experience on top of that. Which will equal out to 145k per game without double experience.

Requirements

-Level 15 or 40 if you do not wish to spend a prestige token on the stinger-
-4 Users with 2 Controllers each-
-Have the kill streaks; Sentry Gun, Strafe Run, Assault Drone-
-Perk 1 - Blind Eye-
-Perk 2 - Hardline-

What to do

Here are the step by step instructions on how to do this kind of boost.

I will lay it out easily.

On side 1 there will be user A1 and user A2, on side 2, there will be user B1 and user B2.
Before you begin the match, choose which users will be playing the first map. Note that there is no option to do round by round.
For this case, users A1 and B1 will be playing the first match.

1. Users A1 and B1 will go to each others spawn and kill the three users. Which will be A2 and B2 with everyone's guest.
2. Meet at the closest bomb site and plant and defuse. DO NOT KILL EACH OTHER.
3. Repeat #1.
4. Once you are at the closest bomb site for round 2, call in all of your current killstreaks. This does not include your strafe-run.
5. Once one user has a Strafe Run, call it in. Have the OTHER user shoot down the heli one in from the left. For example;

HELI 1 ---- HELI 2 ---- HELI 3 --- HELI 4 ---- HELI 5

You would lock on HELI 2, which will destroy HELI 1,2,and 3. Next shoot down HELI 4.

You will get 3k exp per Helicopter. Therefore getting you 9k for your first shot, and another 6k for your second.

6. Make sure to call in and use you Assault Drone (3k exp), and the Sentry Gun (1k exp).

You should be signed into 2 accounts (Main and a guest)

Your main account will be the riot shield, And ur guest will have a LMG Class.

Once you are matched in with a partner in SnD, meet up with him/her in a secure location were no one will die from ricochet bullets.

Now with ur guest account shoot one clip of LMG into ur main accounts riot shield, Take the round time and wait 25 seconds that is when u shoot ur main accounts riot shield again.

The MP5 is unlocked in the very beginning of the game so all players can use it. While Domination Boosting you do not keep your primary weapon out, so technically your primary is optional. This would just be the default selection.

The USP .45 is the first Semi-Automatic pistol you get in the game. You will have this weapon out at ALL times while Domination Boosting. It is NOT one shot one kill so if you accidentally drop your controller, pull the trigger, or get a warning shot, it will not kill the player that gets shot instantly.

Frag, Semtex, Bouncing Betty, Claymore, and C4 all explode. Accidentally pressing the RB (Right Bumper) while having any of the listed above equipped could kill a player(s). Since you look at the ground (using a line for guidance) while domination boosting, accidentally throwing a Throwing Knife on the floor will not kill anyone.

Scrambler is unlocked at a low level, and unlike the Flash Grenade/Concussion Grenade it will not do any physical damage or harm to the other team.

Get to each flag quicker.

Quickdraw, Blast Shield, Assassin, & Overkill are pointless. Hardline can help call in more killstreaks to gain more XP if you are trying to level up quicker.

When using a line Domination Boosting on the ground, you can aim at it for precise movements when capturing. Using this perk you can move in and out of the flag capturing zone faster, causing faster captures and moving off the flag quicker.

Assault is meant to hurt the other team (witch you don't want to do) and you can gain XP using the Support Strike Package. Recommended to use (UAV , Ballistic Vests , Sam Turret). UAV to gain XP, Ballistic Vest to gain XP, Sam Turret to shoot down enemy UAV's for XP and shoot down accidental enemy Helicopters.
