Welcome to the most vital part of the site, the Video Tips. Here you'll find the most important techniques that will help improve your game in Call of Duty 4. I'm not going to bother wasting your time with some BS "strategies" that you'll probably never even be conscious of while you're playing. These are all easy to remember, and easy to learn. Nothing you see here will require a huge amount of skill to pick up, but the skill will come in when you must apply them.

You may not fully agree with everything I say right off the bat, but just give it a try and see how my tips help you. If you're having trouble remembering them, try focusing on mastering one at a time. By the time you have mastered the first 3 of these tips however, I guarantee you will have at least doubled or tripled your

Like the clip says, this demonstrates what I consider to be the very most important technique in the game: Locating enemies by sound. Enemies make all sorts of incredibly loud sounds that you should be able to hear if they are close enough and a chopper isn't right over your head. Such sounds include: Footsteps, reloading, calling in airstrikes, pulling pins on grenades, etc. The most important sound you should listen for is footsteps because once you grow accustomed to hearing them, you should be able to tell which direction they are coming from, and where they are going. A perk that will definitely help you out in this department is Dead Silence. Its purpose is two-fold: It silences your own footsteps, making other people's sound incredibly loud, and it also prevents them from hearing you rush up on them. Meet your enemy where you know they'll be and give them a nasty surprise!

In this clip, I crouch for a moment to listen to sounds over the gun fire. I hear someone approaching from my rear, so I run up the stairs into the room to meet him. After easily killing him, I hear more footsteps, I circle around to meet them and easily kill him too. Right before I kill him I hear some more footsteps behind me. I make a mental note of that and proceed to kill a third guy trying to make his way up the stairs. I finally turn back around and kill the enemy who I heard previously. All of the enemies except for the third that I killed were taken by complete surprise, and at that range, didn't stand a chance to my MP5. This is why it is so important to play with the sound up (preferably with headphones). Listen closely and you'll hear what I heard!

You might be wondering what the hell "Space Invaders" has to do with this game. Oddly enough, it has quite a bit of importance. Space Invaders was an old   2-D arcade game where you blast alien ships trying to land on your planet. They come in rows, and each row shifts forward and to the left, then forward and to the right (kind of like a square "S" shape), making them surprisingly difficult to hit. Well, that's where I got the idea from. The same maneuver can be used in cod4 to throw your enemy's aim way off. If you're still confused about what I mean, YouTube search "Space Invaders."

In this clip, I finish off a guy I put into last stand, and then turn around to hear someone coming in from the back. As we meet, he begins firing his LMG first before I can lower my gun. I remain calm and just quickly shift left, and then right while using hip-fire to take him out. This can be done while sighted in of course, but is best pulled off with hip-fire because you can move a lot faster, which will make you pretty difficult to hit. I probably would have died right there, but this move saved my life. Try it out if you doubt me, you'll be surprised how many people can't hit you unless you're coming at them in a straight line.

This is a pretty simple concept, and one you must pay special attention to when using an unsilenced weapon: Watch your back. In any given match, play as you normally would and record how many times you are shot in the back (or side) after making a kill. If you ratio ends up being about 2:1 or under, you can bet that a lot of your deaths were from enemies getting the jump on you from behind after they heard you shoot. Now when I say behind, that means both literally your 6-O'clock position as well as anywhere you can't see on your screen, such as directly to your right and left. You need to be mentally prepared for the fact that every time you fire your gun, someone is probably going to come after you, or has already spotted you. Don't let that bother you though, instead let that knowledge work to your advantage and rack up some quick kills.

Allow me to go ahead and let you in on a little secret. You're not going to come out on top by sticking behind your team the entire time. Nor will you come out on top by camping. You might get a measly 2:1 or 3:1 ratio, but probably nothing too impressive. If you've ever seen people who consistently get a 5:1 ratio or better with 25 to 30+ kills, you can bet that they are bringing the fight to the enemy, and never slowing down. This should be your mentality. You always need to be cautious certainly, but you should be as offensive as possible, even when your team is cowering behind some claymores somewhere. In team games, flanking the enemy (attacking from the sides or rear) is an excellent choice. Sometimes however, charging straight in will confuse them and take them by surprise. Mix it up and always keep them on their toes.

Any time you attempt to take on more than one enemy at once, you just about triple your chances of being killed. This isn't usually a huge problem in Free-For-All, but what about team games? How do you force the enemy to engage you one-by-one? Well it's all about luring them in. I'm not talking about camping, what I mean is you need to kill one, take cover, then kill another. The main idea here is that you want to funnel them down one path and take them one by one instead of just trying to keep pushing forward while being attacked on all sides.

Running a Circuit is a similar concept to Funneling, except the idea can be applied better to Free-For-All. What I mean by a circuit is a controlled path on the map that you patrol back and forth. It helps prevent you from being shot in the back since you'll constantly be turning and searching for enemies with the 4 S's technique. But more importantly it helps keep you in an area that is ideal to your weapon's optimal range. For example if I was using a Shotgun or SMG, I'd want to patrol an area that has several areas that I can quickly duck behind and use cover if I get attacked over a long distance.
