Alright, this may seem like a tough task, but with enough practice, you'll clear most of the levels with ease. First I would like to clear up a few things:

*You can't get this achievement in co-op, it has to be done in singleplayer.

*You also can’t simply load up the Final Mission, play through it without dying, and hope to get the achievement. You'll have to start from Mission 1.

*The difficulty won’t affect the achievement, so feel free to set it to Beginner (I actually encourage it).

Now then, I highly recommend playing as Fio. Her weapons are much more powerful than any of the other characters (With the exception of the Heavy Machine gun, that one belongs to Marcus. Thanks Kenneth1250), making most of the boss battles a breeze. She also has a TON of ammo for her weapons, which is a massive help in this game.
The other popular choice is Ralf, being because he has the benefit of being able to take two hits before dying. Now he may seem like a tempting choice because of it, but do keep in mind that since his weapons are weaker, you’ll have to dodge more, and you’ll more likely end up facing more than one phase of a boss, which only makes it harder than it has to be.

With the above being said, there is also a DLC character availabe for purchase (80 MSP). RazorPriest has some great information on Leona, so should Fio, Ralf or any of the default characters not suit your needs, keep reading:

‘’Leona has almost as much ammo as Fio, does huge amounts of damage with the HMG (I'd say as much as Marco at the very least), and has a special skill (press Y when standing up, doesn't work when crouching/jumping) that destroys all bullets in a circle around her. It can be used indefinitely and even destroys things like the blue energy balls the 5th boss likes to use, or rockets or pretty much anything you can think of. Even tanks can only take one or two hits from it, and since its animation is not even half a second long, it can get you out of situations where you'd otherwise be completely screwed. Oh, and did I mention she gets to keep her weapons when she dies?’’

Below is a run through the game without dying, or 'No Miss' if you will. Do note however, that it's being played on Hard, so you won't have nearly as tough a time while playing on Beginner.
There is also a few things the player in the video does, which has an easier way to it:

Don't choose the path below. It's much harder than simply following the level straight ahead, which also gives you a tank for the boss.

You may notice that in the beginning, the player is swarmed by soldiers. This is a trick used by most who goes for a good score, so unless you purpousely trigger this, you'll have a MUCH easier time here.

This boss can actually be done in less than a minute on Beginner. As the fight starts, equip your Flame Shot, and shoot 4 times on its lower body to the left, followed by lobbing 4 grenades on it to blow it up. Now fire 3 shots on the upper body, followed by detroying the crate to your right to reveal a vehicle that you now jump in to. Keep firing at the boss and it will die within 10 seconds.

This boss is an absolute joke on Beginner. Once you enter its ''Lair'', you'll notice there's two POW's on each side of the screen, free the one on the right as soon as possible, and pick up the Thunder Shot he drops. Now position yourself on top of the boss, and keep pressing X until it dies. You literally don't even need to move at this point.

The only thing I should mention here, is that to perform what looks like an Uppercut Punch while you're in the huge mech, you hold UP then press B. Using this technique as the Mech boss does his 'Rush' move, you'll have a chance to block it completely. It can prove difficult to time it, as the boss has a tendency to break through it, but the more you do it, the better you'll be at predicting his movements. This attack also deals great damage to the boss.

This may sound crazy, but stay AWAY from the tank in the beginning. It will make things much harder than it has to be. Choosing the tank, the game will pit you up against much tougher enemies than it otherwise would if you chose to go on foot, in which case all you'll face while going down the walkway is 1 plane, the rest being foot soldiers.
The said plane won't even be able to hit you with its missile unless you jump into it, as it will simply fly past you from above.

And that's it, if there's anything you feel like I've failed to meniton, feel free to ask, and I'll gladly add it in. Here's the videos, good luck! (Credit for the vids goes to YouTube user GreedMetal)
