Exposition to CoD Multiplayer is similar to nuclear radiation. You cannot see it, you cannot smell it and you can not taste it. But the long-term effects are severe which is why you need to protect yourself.

One of the most important things that has to be performed right after launching the game is turning off voice-chat:

Wherever you are, be it on a shooting range with hearing protection or in a call of duty multiplayer match with disabled VC. Protecting your hearing is vital and will keep your stress levels low during critical moments. Be advised: keeping VC on will expose you to underage raging squeakers and middle-aged men that explain to you in detail what they would like to do to your mother.

You can find the setting for voice-chat hidden under settings, audio by turning off the voice-chat function there. This will protect your ears from radioactive fallout produced by angry underage squeakers and men with anger issues.

Would you lick the remains of reactor 4 or eat directly from a dumpster or what you find inside public toilets? Obviously not. There is a saying that you become what you consume and there is definitely some truth to it. Which is why the next step is as crucial as it is logical. Turning off text-chat not only will help you to immersive yourself further, it will also prevent you from getting disturbed.

You find this setting hidden under Account & Network.

You cannot. It is sad, but true.

The cheat developing industry is a multimillion-dollar business and there will always be people that will pay for cheats.
The best thing you can do is to not have hard feelings about them.

Always remember that these poor cheating creatures lack everything it takes to properly develop a competitive level of skill.
This mostly comes down to deficits from their early childhood days. Just accept to have them around, since we all know how good they are when their wallhacks and aimbots are turned off.

Just like with nuclear radiation, the toxic effects of CoD Multiplayer can still come through. In event of this happening, you can consider the following things:

• Taking a shower
  
• Hugging a loved one
  
• Going outside

Give me a thumps up if this guide helped you and always remember to stay safe out there! Life is good. Also let me know if you think there needs anything added. Suggestions for aftercare are welcome.

I would like to thank you guys for the overwhelmingly positive support!
Therefore, some bonus content for you guys:

On this year’s iteration of Call of Duty, the spawn system came directly from hell.
If you play in a normal Multiplayer match (or Hardcore) you will most likely already have noticed that enemies keep spawning behind you.
To avoid getting a load of lead from behind you should consider playing in a proper team.

Staying away from the enemy spawn area will keep the matches more structured and will prevent enemies from directly spawning in your back. That can prevent a lot of frustration and works great in game-modes like Domination where its all about keeping chokepoints under control.

And always remember that you need to stay properly hydrated. Being properly hydrated is the key to success.
