Pro-tips for First Person Shooters

I decided to make a small guide for those of you struggling with most first person shooters. This list is relatively generic and applies to most current games out there but it may not be all encompassing. If you would like to add your own tips, please leave them in the comments below.

1. Know the map - This is not limited to just the ins and outs of each environment (although that is key), but it also includes observing player tendencies over time to predict the most likely path they will take. If you notice that your opponents are going to one area more often than not, prepare to meet them there.
2. When In Doubt, Always Know Your Way Out - You will always need to know the way out of every room of every building or corridor you enter, in case you are ever caught by surprise. 
3. Crouch or go prone near cover whenever you can. The smaller the target, the more difficult it is to hit.
4. Understand the Radar -  This is absolutely vital to your survival as enemy movement is constant and fairly unpredictable unless you have a firm grasp of how the radar on your UI (User Interface) functions. If you can maintain focus on that while firing or while moving from cover to cover, you'll be much better off.
5. Know your angles - Know where your blind spots are, the choke points, and what cover you can hide behind.
• Vantage points - any elevated areas where you can view a large amount of the surrounding area you're playing in. Useful for surprising the enemy and scouting ahead.
• Choke point - an area which is 'funneled' meaning it is small and enclosed, and forces the enemy into narrow passageways. This is also known as a "bottle neck".
6. Double Tap - When in doubt, don't get stingy with your bullets. Make sure your opponent is down and STAYS down. Headshots are always preferred over body shots, but make the best use of the reaction time you have. 
7. Don't try to be the MVP (Most Valuable Player) - Don't risk victory just to make yourself look good by trying to pull a "Hail Mary". Play it smart and revive your teammates whenever possible. There is strength in numbers.
8. Communication is key - Being able to articulate quickly and efficiently where your opponents are or where they are heading is important. Every bit of information helps, but do not be excessive.
9. Practice makes perfect - Keep training your aim and reflexes until you are comfortable being able to hit your targets effectively. This more or less ties into knowing your guns, their recoil, and their other stats.
