- 3-02 Upgrade Locations -
---------------------------
** LIFE CAPSULES **
These will give a set Max HP boost, between 3 and 5, depending on the capsule.
You will have 50 life if you find them all, 55 if you include the bonus
capsule. Some of these are possible to miss.
- First Cave: In plain sight as you descend toward the Polar Star, on the left
wall. +3 HP.
- Mimiga Village: Found in Yamanshita Farm on the top of Mimiga Village. Head
to the far right, it's in the small pool. +3 HP.
- Egg Corridor: At the very beginning, you have to drop down to the left just
as the Basil spark hits the wall then chase it so it extends its loop length.
+3 HP.
- Egg Corridor: Go through Cthulhu's Abode and out the top door. Jump left.
+4 HP.
- Bushlands: Just past where you found Santa's Key, go east to a set of two
horizontal rows of star blocks, jump on them and to the left. +5 HP.
- Bushlands: In the Execution Chamber, the tall building with the skull on it
to the right of Kazuma's shack. +5 HP.
- Sand Zone: East of Curly's House and past the Sun Stones, it's in the top of
the first thick pillar made up of star blocks. Try not to blow up all the star
blocks when fighting the Polishes to create a path and reach it. +5 HP.
- Sand Zone: At the end of the hidden path behind a pawpad block on the far
right wall between the Sun Stones and Jenka's house, behind a line of star
blocks. Found next to a chest containing one of Jenka's dogs. +5 HP.
- Labyrinth: Nestled next to the left wall of the first room of the labyrinth
when you're sent there, a ways up into the room. +5 HP.
- Plantation: Sitting on a platform hanging from the far upper-left ceiling.
+4 HP.
- Plantation: Talk to the puppy that appears on the left platform just under
the red skull signs on the top right section of the Plantation after Momorin's
finished the rocket. +5 HP.
- Sanctuary: Bonus life capsule. Found in plain sight as you make your
initial descent. +5 HP.
** MISSILE EXPANSIONS **
These each give +5 Max Missile Launcher Ammo. Your max ammo carries over to
the Super Missile Launcher. You'll have 30 missile ammo if you find them all,
54(!!) with the bonus.
- Bushlands: To the left of the hut in the air above the shack where Kazuma's
trapped. Jump around the series of platforms around where the Save Point is
between the Power Supply Room and Kazuma's shack to reach it.
- Bushlands: Inside the very hut that the previous expansion's sitting next
to. Opening it will trigger a fight with Kulala.
- Egg Corridor?: When you go back to the Egg Corridor later in the game,
you'll find the eggs have hatched. The dragon where Egg 12 used to be is quite
pissed and will fervently guard the chest containing this expansion.
- Egg Corridor?: In the ruins of the Egg observation Room, in plain sight.
Opening it will trigger a fight with The Sisters.
- Sanctuary: Bonus expansion. Just before you fight the Heavy Press at the
far west end of Blood-Stained Sanctuary B3, just past the pillar with 3 Deletes
covering it, in the room filled with flying Butes and with a hanging platform
with an arrow Bute on either side. Above this platform is a single Star Block
concealing a chest containing this massive expansion of 24 Misisles.
** KEY ITEMS **
- Map System
Allows you to press the - Button on the Wii Remote to bring up a map of the
room you're in. The map is tiny, doesn't show your current position and has a
strange graphical glitch that makes the rightmost section of mose large areas
unviewable, so it's of very little use except collectibility.
- Silver Locket
An item found in the fishing hole to the west of Mimiga Village. It triggers
an event in the warehouse at the bottom right of the village.
- Arthur's Key
Found at Arthur's grave in the Cemetary. Use it to access Arthur's house, at
the bottom-left of Mimiga Village.
- ID Card
Found in Egg #06 in the Egg Corridor. Use it in Egg #01 to open the barrier to
the eastern edge of the Corridor.
- Santa's Key
The key to Santa's house that he dropped to the east in the Bushlands.
- Rusty Key
A key Kazuma found in the room he's stuck in. Gives access to the Power
Control Room in the Bushlands.
- Gum Key
Another key conviniently located in Kazuma's captivity room. It opens up the
gum room in the very upper-right corner of the Bushlands.
- Jellyfish Juice
A jar full of juice that you can find by defeating the huge jellyfish stuck in
the ceiling a bit east of Santa's house that only appears after talking to
Chako. Use it to put out fireplace fires; it's also one of three components
needed to create a bomb. It's the only Key Item you can receive more than
once, but you may only carry one at a time.
- Chako's Rouge
Some red lipstick. Obtained by examining Chako's fireplace before you obtain
Jellyfish Jelly, causing her to walk up to you and explain some things, and
then sleeping in her bed while she's standing there. It has no use, other than
proof that you really, really, REALLY like Mimigas, you scoundrel.
- Charcoal
A lump of charcoal found by putting out the fireplace in Santa's house. It's
one of three components needed to create a bomb.
- Gum Base
A stick of chewing gum found in the room in the very top-right corner of the
Bushlands. It's one of three components needed to create a bomb.
- Bomb
A bomb crafted by Malco, in the Power Generator Room of the Bushlands. Use it
to blow open the door of the building Kazuma's trapped inside.
- Curly's Panties
Found in a hidden alcove behind the wall in the bedroom of Curly Brace's house
in the Sand Zone. They have no use, other than proof that you really, really,
REALLY like robots. If you own both this and Chako's Rouge, you are officially
the most envied man in Cave Story! Okay, I made that up.
- Hajime
A dog that stays in Curly Brace's bedroom in the Sand Zone. One of Jenka's
five missing dogs. He's the leader of the bunch.. or so he claims.
Arf!
- Mick
One of Jenka's dogs. He's supposedly an adept treasure hunter, and loves to
sleep in treasure chests. What he does with the contents is anyone's guess.
Found in a chest at the end of a hidden path between the Sun Stones and Jenka's
house.
Woof woof!
- Shinobu
Another of Jenka's dogs. He has poor vision so he prefers to stay in dark
places. Found in an abandoned house at the end of a hidden road that begins in
a false ceiling along the path to the Sand Zone warehouse.
Bow wow wow!
- Kakeru
Yet another dog of Jenka's. He loves bones and has buried them all over the
place. You can find him at the end of the sand-bottomed section of the path
toward the Sand Zone warehouse.
Woof woof woof woof!
- Nene
A beautiful dog, the only female of the group. She sleeps all the time, and
can be found taking one of her long naps at the very end of the lower path of
the Sand Zone, right next to the warehouse.
Wan...
- Life Pot
Restores all of your HP when used. It can only be used once, and there are
only two in the entire game, so use wisely!
- Turbocharge
If you chose to take the Machine Gun from Curly in the Sand Zone, then you can
receive this for free from the Gaudi shopkeeper, Chaba, in the Labyrinth. It
speeds up the recovery rate of ammo for the Machine Gun.
- Clinic Key
Opens the door to the Labyrinth Clinic, the building with the cross above it
up and west from the Camp. Obtained from Dr. Gero, the physician in the Camp.
- Arms Barrier
Halves weapon EXP lost when you take damage. Found the top part of the Camp,
accessible via a hidden passageway in the ceiling in the large Labyrinth room
from which you can access the normal Camp entrance and the Clinic nearby.
Unless you took the Machine Gun, you'll have to come back to this area with the
Booster to be able to reach it.
- Cure-All
A pill found in the abandoned Clinic in the Labyrinth. It supposedly has the
ability to cure anything. Give it to the Physician in the Labyrinth Camp.
- Booster v0.8
A jetpack that can be equipped and unequipped from the inventory menu. Once
it's equipped, press and hold Jump while airborne to launch upward for a few
moments. Can only be used once in the air until you hit the ground again.
Received in the Labyrinth, past the Clinic and Camp.
- Booster v2.0
A powerful jetpack that allows you to move freely for a time at high speeds in
midair if you press the jump button. If you want this instead of the Booster
v0.8, jump over the large gap in the Labyrinth room where Professor Booster
falls down by leaping just at the red marker on the ground. It's required if
you wish to access the hidden, super-difficult Sanctuary area at the end of the
game, but you may want to go for the normal ending with Booster v0.8 first.
- Tow Rope
A tow cable found in the far lower-right corner of The Core (only appears if
you didn't take the Booster v0.8). It was used by the robots who came to the
island years ago to carry downed comrades.
- Curly's Air Tank
Given to you by Curly Brace after the events at the Core. With it, you're
automatically encased in a bubble whenever you enter water, giving you infinite
air.
- Alien Medal
Reward for defeating Ironhead (the boss of the Waterway) without taking any
damage. It's engraved with an image of Ikachan, the hero of a game named after
himself that was Studio Pixel's previous work before Cave STory.
- Whimsical Star
A trinket that you can receive from Chaba, the Gaudi shopkeep in the Labyrinth,
if you talk to him with the Spur weapon in your posession. It will cause small
stars to float around you as a meagre shield when you charge the Spur to MAX.
- Teleporter Room Key
This key is visible but unobtainable behind a cluster of instant-death spikes
in the pools at the bottom of the Plantation. You'll need to talk to Kanpachi,
the fishing Mimiga, to help you get it. Use it to unlock the room just west of
where it was fished up.
- Sue's Letter
You'll find this stuffed in your inventory after you wake up inside the jail.
It's a leeter from Sue explaining a lot of what's been going on as far as the
story that you've had to just piece together by this point. It also contains
the password to enter the Safe House on the Plantation.
- Mimiga Mask
A head covering that looks just like a Mimiga. Wearing it will allow you to
speak to the Mimiga in the Plantation who aren't allowed to speak with humans.
- Broken Sprinkler
A broken water sprinkler from the Plantation. Useless by itself, but can be
traded to Megane in the Plantation Rest Area.
- Sprinkler
It's new... isn't it? This can be taken back to Momorin in the Plantation Safe
House to help complete her rocket.
- Controller
A technologically impressive device that could only have been made by a master
technician. Too bad he's a big fat coward. Obtained from Itoh after giving
Momorin the Sprinkler.
- Mushroom Badge
Useless item given to you by Ma Pignon in hopes you'll leave him alone. I hope
you know how to answer his questions correctly even if you want this garbage.
- Ma Pignon
Mystical, ultra-rare mushroom that's said to restore people's memories. Has a
smart-aleck personality and is known to be a surprisingly potent combatant, as
well. Found in the small storage room above the Mimiga Cemetar.
- Mister Little
This guy's very, very hard to see and has gotten himself very, very lost. At
the end of the game, you can find him wandering around the Mimiga Cemetary.
It's said he is the proud owner of the world's most splendid gun. Has a
fascination with fine blades.
- Medal of the Red Ogre (aka Clay Figure Medal)
Proof of the warrior who's finally able to put an end to the Red Ogre. It's
extremely heavy despite its size.
