This cheat turns all the enemy drones into
stick figures with big pants. "Ants into
Pants" becomes available in the Cheats
menu (located under Options) as soon as
you have collected 300 enemy heads.

Break Fall
Any veteran Mario or Banjo-Kazooie player will have already figured this
one out. Falling from high places causes your character to take damage,
but you can break your fall with the help of Lupus' rocket paws or Vela
and Juno's jetpacks (only if you have fuel, in the case of Vela and Juno).

Change Characters on Map Screen
Not really a gameplay tip – but this feature isn't mentioned in the manual,
so we figured we should include it. There is no need to go to the Character
Screen if you need to quickly change characters when selecting a new
world to fly to. You can change your character on the map screen, too.
Simply use the C Buttons to switch the player icons in the corner until
you've got the character you want

Debug Mode
To activate debug mode, first you must start a game normally. At the
character select, hit right on the joystick 3 times, then left all the way to
Lupus (select Lupus). When you start, hit C-right, C-right, C-right, C-left,
C-right, C-right, C-up, C-up, C-up. If you do it correctly you will hear a
noise that sounds like Lupus barking but he won't be moving. To use this
cheat, after the bark, just go through the items and weapons you want to
change into by tapping A. Hit A once, it changes, hit A again, it changes.
just cycle through till you have found what you want. Then hit B to place
that object/item where Lupus is standing.

main characters into kids.

Jetpack Tip
Another little feature not mentioned in the manual: use the C Down button
to hover in place when using the jetpacks. It only uses half the fuel.

Kill The Fish in Goldwood
Sick of just feeding the fish? Feed em' explosives! Go to the place were
you find the Shurikens, but don't go inside. Around the door there is a
pond with fish in it. It is deep enough for them to swim in and shallow
enough for your bombs to go into. Try remote mines. Also, make sure to
get close enough so that you blow them up.

Let Floyd Help
If you want to save on ammo, use Floyd -- even if a second player is not
available. Find a hiding place, like a crate or a rock, stand behind it and
press START on the second controller to activate Floyd (once you have
put him together on Tawfret). Now shoot down your enemies from a safe
distance, without wasting any ammo. Do the same if you want to take out
crates. You can also use Floyd to snip – even when you don't have sniper
rifle ammo. When playing with two players, player one can hide behind a
box and zoom in on far away enemies with the sniper rifle. Whether player
one has a clear line of fire or not, Floyd's higher up position ensures that
player two can do the work – without wasting ammo.

them, including the target ranges, the 2D Super Sprint clone and the 3D

Reach High Up Gems
In order to grab the many health gems located in seemingly unreachable
areas -- such as on the SS Anubis generators or on beams in the cave
levels -- shoot them using your pistol or machine gun. If you hit them
correctly, they will move and slide down to your level.

Remote mine warning
In multiplayer mode, if you are near a remote mine, you will continueosly
hear a very soft buzzing sound, so beware of the buzz.

Secret Flame Thrower Ammo
If you're low on Flame Thrower ammo, look for Tribals that carry lanterns.
Shoot these Tribals once to make them drop their lanterns (be careful not
to kill them), then pick them up to use the fire as Flame Thrower ammo
submitted by IGN64

Selective Ammo
If you're running low on ammo for the Shotgun, Pistol or Machine Gun,
select the weapon you want to refill (even when it's empty) when collecting
weapons from dead enemies. This will automatically give ammo to the
weapon you picked. This strategy is invaluable to keep your Machine Gun
ammo count high.

Special Item Locations
Jet Force Gemini contains a number of special items in addition to the
regular power-ups such as gems, backpacks and Gemini Holders. This
listing tells you what the items can be used for and where to find them. 

Fish Food
Where: Goldwood, first area after landing pad (treasure chest)
One of the first secrets in the game can be accessed right from the
Goldwood entry area, even before you enter the Outset zone. Look for a
secret passage near the right rock wall. Behind it, you will find the fishpond
and a treasure box that contains fish food. Although it's listed among your
weapons, the fish food is hardly lethal. You can use the fish food to feed
the fishes (duh) or other hungry creatures, such as the creepy maggots or
Flopsy the dog (which keeps them from attacking you). The food can also
be used to distract your enemy or to detonate proximity mines without
wasting any ammo. 

Ear Plugs
Where: SS Anubis, Hold (Floyd Mission)
The ear plugs are the perfect protection for sensitive ears, especially when
around noisy Tribals – but the Jet Force team can't use them. To get the
ear plugs, get a Gold or Expert rating in the Floyd mission in the Hold area
of the SS Anubis. Once you have access to the Water Ruin stage, bring
the Ear Plugs to Ivana the Bear. 

Pants
Where: Tawfret, Bridge (on top of a tree)
What a charming place to forget one's shorts... In this desolate swamp
haunted by zombie drones and giant bettles, a pair of shorts hangs from a
tree. Bring them to their rightful owner, Gimlet, who awaits in the same
stage. 

Crowbar
Where: Tawfret, Bridge (from Gimlet)
This handy tool lets you open the heavy trap doors on Tawfret and
Walkway. To get it, bring the pants back to Gimlet. 

Jeff & Barry II Arcade Chip
Where: Ichor, Military Base (Floyd Mission)
Only if you have found this circuit board can you play the Jeff & Barry II
racing game in the nightclub arcade on Ichor (Jeff & Barry I can be played
without it). Get a Gold rating in the Ichor Military Base Floyd Mission. 

Specialist Magazine
Where: Eschebone, Cortex
Cough. Specialist magazine, eh? We know where you can find it – if you
want it... Go to Eschebone's Cortex stage to find it, then bring it to
Fernando who is hanging out on Rith Essa (Bluff). Fernando will give you
the Mine Key in return for the... uh... inspiration literature. 

Mine Key
Where: Rith Essa, Bluff
You need this key in order to get into the Rith Essa mines. Once you've
got the Specialist Magazine from Eschebone, visit Fernando and trade it
against the key. 

Gold Bars
Where: Celulean, Dune
Look for three gold bars in the Cerulean outdoor area. You can use them
as payment for Fish Face's Tri-Rocket Launcher in the same level.

Tips for the Final Boss
The Final Mizar on the Asteroid is easily the toughest, cheapest Boss in Jet
Force Gemini - you'll no doubt die many, many times facing him. There is a
trick, though - although it's not foolproof, it's a big help. To do this trick,
you need to have at least 40 max Tri-Rockets with Juno. For defeating this
Boss, you'd usually fire a Homing Missile when Mizar turns his back,
because it almost always hits. Unfortunately, it's also weak, and it can take
up to 21+ of these hits to get Mizar to go to this next phase. The trick is to
use the Tri-Rocket Launcher when Mizar is flying toward you to do his
Fire Claw attack (the one that creates the shockwave). Aim high and
shoot once straight into Mizar's body as he comes toward you, and you'll
almost always hit AND do more damage, too. If done right, this can cut
the hits you need to get him down to his next phase by half.

Once he's in his next phase (on the ground with you), start pounding his
right (your right) arm with the TRL, until it explodes in a bloody mess; then
do the same with the left arm; then do the same with the head, and he's
through. Don't forget, Mizar also attacks you too, so here are some tips in
avoiding his attacks.

Meteor Barrage - When Mizar uses the Meteor attack, having an extra
friend around to control Floyd and help you destroy meteors while at the
same time conserving machine gun ammo, can be a great help. Not only
do you avoid running out of ammo, which is easy to do, even with 900
rounds, but you also get hit fewer times!

Fire Claw - Mizar charges the platform you're on and causes a shockwave
which takes 1-3 HP of damage. To avoid this, go to the far left or right of
the platform and wait until Mizar is just about to strike the ground, and
strafe in the opposite direction. The shockwave isn't large enough to cover
the platform and so it will miss you.

Eye Laser - Mizar fires two purple lasers from his eyes three times at you.
Simply strafe to the left or right to avoid. Easy. One of these his can take
1-2 HP of damage.

Ice Breath - Mizar blows a huge breath of cold air at you. Very easy - just
strafe right through it and it probably won't do anything. If it does, it will
only do 1 HP of damage.

Lightning Cord - The most lethal of Mizar's attacks and the hardest to
avoid. Mizar guides a cord of electricity along the platform at varying
speeds. Being struck by this cord for half a second depletes 2-3 HP; being
stuck in it for any longer than that depletes 1-2 whole life BARS, if not
more. The only way to avoid this is to play jump-rope with Mizar.
Carefully jump the cord as he guides it back and forth. If you're VERY
good and VERY lucky, you'll take minimal damage. Luckily, once in his
second phase, Mizar doesn't use this attack any more.
