Star Fox 64 reference: 
When you defeat Pigma when he becomes a Apariod next to the Arwing, it will 
show Sector Y from Star Fox 64. 

Queen referred to as boy:
When you fight The Queen (the last Boss), some time during the battle with her 
first form Falco will indicate that the queen is a boy by saying "He just won't stop".

Defeating the Aparoid Queen:
The Aparoid Queen has three forms that you must destroy. In stage one, you will 
see the Aparoid Queen during the intermission sequence and notice that Pigma, 
General Pepper, Peppy, and Fox's father have been absorbed. The queen tries to 
stop your mission. Destroy her armor and avoid the attack she sends at you. 
When you see the red jewel, attack it when you have the chance. After her health 
has been depleted, you will see an intermission sequence where Fox shoots the 
self-destruct program into the hole that you opened. However, she will get away 
and try to create an antibody to get rid of the program. In stage two, shoot the 
four red "eyes". Then, shoot the head that comes out of the body. Shoot the gold 
armor on her head to reveal the weak spot. Watch the head's movement and 
breath attack. If you have the Hyper Lasers, this should be easy. In stage three, 
she will be in her last form. Just shoot the eye and it is over. She has two attacks 
remaining. If you start to see green barriers in a circle, fly in the center and 
attack her. Watch out for the beam that she fires at you

This trick requires a controller with an auto-fire feature. Use the auto-fire on the 
Apariod Queen to destroy the armor and kill her weak spot. You will have to fight 
her again. Destroy the pink balls and the armor on thye snake-like head thing. 
Shoot the orange ball on it and repeat. Finally, just shoot her. She will be shooting 
fire or a green thing that she spits out. The fire can be easily avoided. For the 
green weapon, you must stay in that thing without touching the green wall.

Defeating the Hatcher leader:
Shoot the bubble-like object that is on the bottom of him. After that he will fall. 
Get on him by pressing Y. Finally, keep shooting that bubble-like object on top of 
him. If you fall off, repeat those steps.

Defeating ground enemies:
If you have Sensor Bombs and a Booster Pack, you can perform a devastating 
attack on ground enemies. If an enemy is standing relatively still (for example, 
trying to snipe someone) fly over them with your booster. When you are 
overhead, "plant" a Sensor Bomb. It will automatically fall to the ground, where it 
will soon explode.

Quick vs. mode matches:
Note: This trick requires two controllers. Use the following trick to get all the vs. 
mode unlockables quickly. At the level selection screen, press Y and the options 
should appear. Select "Sniper Showdown". Then where it reads "Point" change it 
to "Survivor". Next, set the number of lives to "1" and select "OK". Once back at 
the level selection screen, choose "Simple Map 1". You should start very close to 
your opponent. Shoot them and they should die in one hit. Once it is over, just 
select "Retry". Keep doing this until you unlock the desired bonus. When you 
unlock "Sure-Shot Scuffle Mode" at fifty matches, you can accumulate matches 
even faster because you can kill your opponent in one hit with any weapon.

Another way to accumulate versus mode matches quickly is to make the settings 
Sure Shot Scuffle mode (50 matches) and survivor, one life. Choose the Outer 
Sargasso Hideout stage. With whichever player you want to lose, press the Analog-
stick all the way Left. They will crash into the wall and die. After it is over, 
select "Retry" until you unlock the desired item.

Effective Predator Rocket use:
When you get the Predator Rockets, land some where far from your opponent. If 
your character can jump high, jump towards your Arwing's or Wolfen's wing. Plant 
the rockets on it. Put the last one on top of the cockpit. If you put it on the tip of 
the ship and try to shoot your opponent, it will destroy the rocket. If your 
opponent gets in an Arwing or Wolfen rush over there and get under him or her so 
that the rockets can fire at your opponent. Note: If you are doing the breaks when 
they fire as the Wolfen, the rocket will hit you.

Avoiding Predator Rockets:
Get someone on your Arwing and have them shoot the rockets behind you, or go 
full speed on the ground and before you hit the ground, go up. The rockets will hit 
the ground and explode.

Avoiding Landmaster charged laser: 
If your character jumps high, you can avoid the charged laser by jumping only 
when close to your opponent that is in the Landmaster.

Ride on Arwing or Landmaster in multi-player mode:
Note: It is strongly recommended that you practice this a few times with a friend. 
Go to a level with pilots, Landmasters, and Arwings available. Try Corneria City, 
as there are many good places to board a ship. Choose a character that has a two 
to three star jumping ability. With a friend, make your way to either the Arwing or 
Landmaster. Have you or your friend jump onto the wing of the Arwing or the side 
of the Landmaster. Whoever does this should press R to keep steady. Then, have 
the other person press Z to start driving or flying.

Use the following trick to stand on the wing of an Arwing while nobody is driving. 
Note: It does not work on a few stages. Press Z on hop into an Arwing. While 
flying, press Z again and you will be on the outside of the ship. You can press Z 
again to get back into the ship. While you are on the Arwing, you can shoot any 
weapon that you could normal shoot on the ground. If you jump off the ship you 
will land on the ground and suffer no damage. The Arwing will go to the edge of 
the level until it explodes. The Arwing will then appear on the ground in less than a 
minute.

Multi-player coordination:
In 2 vs. 2 mode set the game on Arwings and Landmasters. When the battle 
starts, have one person drive, then hop out. Then, let the other person drive and 
you will be able to get a ride to your own vehicle or help and be a gunner. Note: 
Beware of Arwings. When you are on the Arwing you should have the gunner have 
homing rockets. In the Landmaster you should use machine or gattling guns. Once 
in awhile you should switch locations.

Arwing decoy:
In multi-player mode, go to a level that has Arwing and on foot rules. Get into an 
Arwing. Go to a place where the other player cannot see (make sure he is not 
looking on your screen) and jump off with Z while making the Arwing go over your 
opponent's head. Then, while he is following the Arwing, shoot him with your best 
weapon.

Arwing surviving the Demon Launcher: 
If your opponent shoots a Demon Launcher at you, get out of the Arwing. Put your 
barrier on and the Arwing should survive. Note: Your Arwing needs full health to 
survive that blast, or simply just jump out of the Arwing and fall.

Things to do on the wing of an Arwing: 
Use the "Ride on Arwing�" hint. Some fun things to do include using hard-hitting 
weapons such as the homing rocket launcher, gatling gun, or machine gun. You 
can strap a Fireburst Pod onto the wing and have some nice explosive fun, 
watching the fireworks from the sky. Another good idea is to simply cover the tail 
of your ally's Arwing, just to make sure no one sneaks up behind you. Also, if you 
happen to have a Demon Launcher, you can really do some damage firing at 
other Arwings from a good spot. Overall, it would be a good idea to pack a Barrier 
along because you will be very vulnerable.

When you are saved by Wolf or Falco, you will use the plasma cannon. However if 
there are no enemies you can still use your other weapons and have fun with it.

Easy health:
Save your teammates to regain health.
