If your trying to play Call of Duty competitively you want to play to win, these are a few tips to help you better your game. I have been playing Call of Duty since CoD4 and I've been playing on MLG since 2009.

If you want to become good at the game, these are must haves.

1. A sensitivity that you feel comfortable using...
I suggest using (Medium) on any Call of Duty.

2. Find your play style.
You can be an Assault Rifle player, a SMG player, Objective Player, Support Player. Whatever you choose to be this will help you if you stick to the one role. You'll know your role inside and out and know how to help your team win games.

3. Play with friendly people.
You don't want to play with people who shout at you for a tiny mistake that you made, you have to take responsibility for stupid mistakes that you made and become a better player from it.

4. Spend, Spend, Spend
I have spent A LOT of money on making my playing experience better. Try and have yourself a good monitor to play on (my monitor has 1ms response time), try getting a scuf controller (to make your reaction time to jump quicker and shoot faster), buy a good headset. Hearing is everything!

5. CONNECTION MATTERS
If you have a bad connection, you may as well quit right now. Every CoD game is connection based. Try having a good connection, it seriously makes you win more gun fights.

6. Enjoy Yourself
Make sure that when you play your not constantly crying/raging... Its okay to do it sometimes but when you rage it makes you play worse.

That's all I could think of, if I missed anything just comment it below.
Thanks for reading. Bye!
