First stage save Falco and go under all the arches in the water and you will fight a different boss. 

Corneria
Easy Route-Meteo
Advanced Route-Sector Y

Medal Requirement-150 kills Note:All wingmen must be alive at each mission in order to get a
medal. 

To take the advanced route to Sector Y, save Falco just after the check point. Then fly throught all
the archs in the water. You may want to brake to go through the last arch to avoid colliding with it.
To reach the medal requirement you may have to break continuesly and shoot everything you see. If
you don't reach the medal 

requirement, chances are you made at least 100 kills. When you reach the map screen press start
and the Retry Mission, you'll lose one Arwing, but as long you keep getting at least 100 kills, it'll be
like you just started the game. This way you can try to get the medal again. Do this for all other
missions too. Note:Sometimes you'll get more than one life from a mission. 

Meteo
Easy route-Fortuna
Secret Route-Katina
Medal Requirments-200 kills

There are three meteor rings at the beginning of this mission, fly through all three and a laser power
up will appear. After the first tunnel there will be fore meteors clumped together, fly through them to
make a Laser Power up or a wing repair appear under a meteor. To kill the boss shoot the triangles
that are not hidden by the sheild which asorbs lasers. When the triangles are gones, avoid getting hit
by the sheild then shoot the glowing spot in the center. Avoid the electric blasts the boss shoots at
you. Just stay away from the center of the screen and you won't get hit by the electricity. After you
destroy the center the boss will turn around and shoot ring lasers at you. To avoid them turbo
forward. Shoot the two glowing spots and he's done for. To reach the secret area go through the 5
blue ring after the checkpoint, you'll start to spin, and the faster you go, the harder it is to go through
the rings, just start turning for the next ring as soon as you enter a ring. If you get them all, you'll
warp to a secret level. To get a medal, shoot all the enemies you can before taking the warps (you
may want to shoot bombs into areas with a high concentration of enemies). After you take the warp,
there are plenty more enemies. Shoot a bomb in to the center of the striped astroids to get most of
them. When you see a whole bunch of power up clustered together, try to get the bombs using a
loop. Shoot bombs into areas with a lot of enemies too. The warp will take you to Katina. 

Fortuna
Easy Route-Sector X
Intermediate Route-Solar
Medal Requirements:50 kills

To get a medal here, you'll have to shoot as many of the enemies coming out of the base you can.
Try to lock on them by charging your lasers. Then when Wolf Squadron arrives, take all of them
down too, don't let any of your team mates do it. Keep shooting enemies and you'll get a medal. To
take out Wolf Squadron, wait until one of them are behind you, then do a loop, they'll be put in front
of you, then shoot them with rapid-fire lasers. If you become real good in this game, you'll won't
have to wait for them to hunt you down, you can go hunt them! :-) Charging your lasers and locking
lasers don't do much damage, but is good for getting them off one of your wing men backs. Be sure
to answer their calls for help. Defeat Wolf Squadron in the set amount of time, and you'll go two
Solar, if not, you'll go to Sector X, and whatever is left of them will return for a rematch. 

Sector X
Easy Route-Macbeth
Secret Route-Sector Z
Medal Requirement-200 kills

If you come here from Katina, Bill will come to help you out. To avoid the bombs stay to one of the
far sides of the screen. Right after the bombs, shoot all three mines right next to each other to get a
laser power up. Trying locking on with lasers. Soon, directly when the second arm to the boss flys
past (it looks just like the first one the punches open a wall right after the check point). If you go to
the left, you'll fly past four grey gates. Shoot open these gates and fly through them to take a warp to
a secret area. When you shoot open the gates, Bill will help you open them. But don't rely on them to
much. Keep the brake button pressed and turbo fire the doors open, they turn from grey to red (hope
you have at least twin lasers, and you might want to use a bomb if you get too close to them). If you
make the warp, you'll go to a harder secret area. Ignore the baddies and just shoot the ones who get
in your way. Avoid the beams by turning with them and flying close to the center of them. When you
reach the second spiral, right after the first, you might want to do a Barrel Roll to turn faster near the
end of it and turbo. Stick to the center of the the rest of the beams. When you reach the squares,
shoot the enemies in your way and fly through them and hope you made good timing. You may be
able to turbo or break to avoid getting hit, but don't count on it to much. If you take the path to the
right, or, you don't take the warp after taking the left path, you'll face the boss. Shoot the bosses
eyes, after a while, you 'll destroy the big head and then have to shoot the little eye. Destroy him fast,
other wise Slippy will try to take him and end up getting knocked into titania, where you will have to
save him. If you destroy the boss in time, your off to Solar. To get a medal, you don't need to take
the warp, (you don't need to in Meteo either, it's just easier taking the warp). Just destroy everything
you see and use bombs in high concentrations (like right at the beginning of the mission). Take the
the right path where it splits. They're are loads of enemies and guns to destroy, use the breaks to
take out them all. 

Bolse
Easy Route-Easy Venom 
Medal requirement-150 kills

At this level, the base is spining or something, and it's easyier to shoot the poles and things by going
right. This way, the target (not the baddies) is always in front of you, and you'll have to turbo to the
other targets. At each pole, destroy the to guns and the bottom to get power ups. Then destroy the
the top of the poles. After this, more baddies will appear, and you'll have to take them out. Try
locking on. After a while, Wolf will appear (or whatever is left of it). Take them out the same way
as Fortuna. Then take out the core by shooting the glowing squares. To get a medal, you'll have to
shoot as many enemies you can. Then take out wolf squadron, it's better you avoid going to Fortuna
so you can take them all on here, so you can get the most points out of them. When you're done with
Star Wolf, take out all the baddies until no more enter the fight. Then take out the core. You should
then get a medal if your wingmen are alive. 

Easy Venom. 
Medal Requirement 200 kills. 
Note:This only applies if you arrive via easy route.

Don't worry about getting a medal here, it's to hard. It's easier to get one on Advanced Venom. Just
shoot so you won't get shot. The Boss is a stone runner. Don't shoot the head and shoot everything
else. He'll make poles come out of the floors and walls and make beams fall. Avoid them. When you
take out his armor, his head will turn red, then shoot his head. During this time he'll make a whole lot
of beams come out of the wall. You better break! It's very hard to avoid them! When you get read
of the head armor, shoot the center of his back. Then you got him. 

Final Boss-Easy Andross
There are to ways to take Easy Andross out. But this way doesn't take up less time. Shoot
Androsses eyes. They'll flash red. After a short while, Andross well grimace and hold up a hand.
Shoot the hand. If you don't destroy the hand, he'll shoot electricity at you. To avoid it, go to the
opposite upper corner of the screen. Repeat this procedure until both hands are destroyed. Then
shoot his eyes. When Andross tries to suck you in, either brake or go the lower right corner of the
screen, or do both. You won't get sucked in. Then shoot the rocks he spits at you. So you will
destroy androsses face, and you discover he's a droid, or you would if I didn't tell you. Shoot his
eyes. The barrel roll out of the way and stay out of the way when he tries to chomp you. Repeat the
procedure, eventually, you beat him. 

If you earn a medal on every level by getting a certain amount of "HITS" (between
100&300depending on the stage) you'll open up playing with tanks in multiplayer and playing the
extra hard mode. Fox even wears sunglasses! If you earn all of the extra mode medals, you get a
new title screen and open up playing with the Fox team on foot in multiplayer!
