“Alter your controller sensitivity to become more accurate. Professionals use lower sensitivity – around two to three – for long-range shots with assault rifles. For sub-machine guns, opt for five and above. This higher sensitivity also makes you more agile while moving around.” 

2) Hear no evil
“It’s worth investing in a decent gaming headset. The crisp audio allows you to pinpoint your enemies from their footsteps, without your mum drowning them out with the hoover.”

3) Perks of the job
“What type of role are you fulfilling? Getting flags? Planting bombs? Hiding in a corner trying not to get wasted? To aid with the match objectives, it can help to have the faster moving perks. But if you simply want to kill, go for offensive ones.” 

4) Chill, Winston
“We know getting continuously capped by a bolshie 12-year- old called KillaPeniZ69 is frustrating, but stay calm. Your anger will cloud your judgement, so you’ll miss what’s happening on the screen.”

5) Good CoD
“The pros name every part of the maps with different callouts. If you get killed, tell your teammates the enemy’s whereabouts, using the callout for that part of the map.” 

6) Learn or get schooled
“It’s simple: if you know the busiest parts of the map and the hiding spots, you can plan your tactics accordingly.” 

7) Wait, then reload
“You’re at your most vulnerable while you’re reloading. You can’t do anything once you’ve hit that button, so never do it unless you’re behind cover.” 

8) Know your role
“This may sound like the opposite of fun, but if your whole team is simply going after kills in Capture The Flag, you’re never going to win. Make it clear who should do what and your team will fare better.” 

9) Learn from mistakes
“If you’ve just been trounced, the last thing you’ll want to do is watch it again. But this is how you can pick up on some of your more common errors.”

10) Know your enemy
“Learn how your opposition is playing; do they keep rushing towards your team? Well, simply sit and wait for them… at the end of your scope.” 

11) Watch your back
“Maps like Express include speeding trains that can kill you. Keep off the tracks!”

12) Keep moving
“If you’re stuck in a firefight behind cover, don’t pop out from the same place. Instead, crawl or move somewhere to shoot from a different angle.” 

13) Cook grenades
“Press the grenade button and hold it for a few seconds, otherwise your target will have time to escape. Use semtex to stick explosives to enemies with shields.” 

14) Ditch the TV
“Forget your HD TV. Any TV over 32" will have up to eight milliseconds of lag, but on a computer monitor, you’ll only have two milliseconds, making you a faster killer.”  

15) Lightweight perk
“This decreases damage when you fall. If you see enemies below, leap, survive… and make yourself unpredictable.”
