Daisuke “Pixel” Amaya, for creating Cave Story.
Nicalis, for updating Cave Story multiple times (such as Cave Story 3D and Cave Story+).
Steam user MasterLuigi452, for his brilliant Sanctuary guide that I mentioned and for fixing a few errors regarding difficulty differences.
The first achievement you’ll get, which is impossible to miss. When you start the game, exit the room that you’re in and head left, then fall, then head right. Enter the room and open the chest to get the polar star.
Get some jellyfish juice from the big jellyfish in the Bushlands, then go back to Mimiga Village. Go into the main hall (the big house next to the graveyard) and use the juice on the fireplace. You’ll then find the bubbline.
The missile launcher is located in a chest in the egg observation room in the Egg Corridor (the room with the elevator to the left).
NOTICE: By obtaining the machine gun, you will not be able to get a few more weapons which unlock achievements
When you beat Curly, you can talk to her anytime to trade your polar star for her machine gun (though you’ll be unavailable to do this later on).
In Mimiga Village, go outside of the save room door and fall down to the right. Land on the platform and then hop onto the platforms to the right. You’ll find the map system in the chest.
When you find all of Jenka’s dogs in the Sandzone, Balrog will steal the key and Jenka will talk to you. She’ll give you the life pot when she’s done talking.
To get the alien medal, you need to defeat Ironhead (the big fish in the Waterway) without getting hurt. I suggest that you save at the save room where you fix Curly. The easiest way to do this is to level up your blade to level 3 so that you can use it to take out all of the small fish, and to have your super missiles for Ironhead. Then just keep firing at Ironhead when he comes. If get hit, just restart and you’ll be at the savepoint.
Can only be obtained if you decided to take the save Curly path. After you lose Curly at the Waterway, head to the Plantation, and head to the bottom right area. You’ll find Curly in a bed, all safe and sound… until you find out that she lost her memory. Talk to the guy next to her and he’ll say that you need a special mushroom to restore her memory.
Now head to the graveyard in Mimiga Village and go to the top right area. Use your booster pack to get to the door above. When you’re in, talk to the mushroom, and he’ll ask you some questions. Answer in order: Yes, yes, no, yes, yes, no. When you’re done talking to him, he’ll give you a mushroom medal. Observe it by opening it in the menu, and you’ll find that it’s worthless. Talk to him again, and you’ll have to fight him. Just shoot him with any gun (spur is the best) and be careful of the falling rocks and the clones of him that he’ll send. Once you beat him, you’ll obtain him as a pick up item.
Near the start of the game when Toroko gets taken, you’ll have an option to fight Balrog. Choose yes, and fight him. He’s rather easy, though be careful of his jump attacks. Aside from that, just keep your distance and keep shooting him.
You’ll find Igor at the end of the Egg Corridor. Just keep shooting at him with either the polar star or missiles, and keep your distance.
You’ll fight Balrog again when you get to the Bushlands and turn on the robot. He’s a bit more difficult than before, mainly because he flies above you and can land you you. I suggest leveling up the fireball and constantly fire it at him when he lands or when he’s in the air (aim up). Or just shoot him with the polar star.
You’ll fight Balfrog at the end of the Bushlands while getting pieces for the bomb. I suggest you level up your missiles before you fight him. When he’s coming to you, use the fans to fly over him and when he opens his mouth, fire rockets at him. Take care of the small frogs with the fireball.
You’ll find Curly when you arrive at the small house in the Sandzone. She’ll think your a mimiga killer and attack you (along with some mimigas). Use the fireball to take out the mimigas, and hit Curly with either the polar star or the fireball (she blocks all missiles). Remember to jump out of the way when she’s about to fire her machine gun.
Omega is located at the far right of the sand zone. To fight him, you’ll have to shoot him while he’s unleashing enemies. The fireball is the best choice since he spends most of his time in the ground. Once he’s done shooting, take out the enemies until he starts unleashing more. Also be careful of his jumps.
Make sure you have a dog with you before fighting Omega to get another achievement (see below).
When you get to the Labyrinth, you’ll have to head to an abandoned hospital to fight Puu Black. He’ll attack you with flying objects and will fly up and back down on you. Use King’s blade to take him out quickly (if it’s level one and you’re quick enough, you can defeat him in seconds). Be careful because you can still get hurt by him when he’s defeated.
After you give Curly the cure-all in the Labyrinth, head to the right and you’ll have to fight a giant machine called Monster X. Take care of all of the cricket-like enemies first, and keep hopping over the monster when it’s coming for you. When the center of it opens, fire at it with either King’s blade or the missiles. Also be careful of the little green missiles that will circle around.
In the Labyrinth, hop over the hole where Professor Booster falls down and enter the room. You’ll talk with Curly and have to fight Balrog for the third (and final) time. Even for the third time, he’s still really easy. He’ll just walk towards you everynow-and-then and fire a few missiles. Just hop over them and fire at him with any gun and you should beat him in no time.
If you jumped over the hole where Booster fell, go into the door and proceed normally. You’ll eventually enter a chamber with a giant seed-like machine (I highly suggest you grab the tow rope to the bottom right so you can save Curly afterwards). When you talk to Curly, the fight will begin. Shoot at it’s eye when it opens (I suggest using the super missiles) and shoot at the other enemies when it’s closed (keep in mind that you can hop on the other parts of the boss). Also make sure that you’re as high as you can be, because the area will flood everynow and then (and it usually takes a while for the water to come back down).
At the end of the Waterway (after you beat the Core), you’ll have to fight a robot shark called Ironhead. I suggest using King’s blade to take out the small fish that can hurt you, and when Ironhead comes toward you, use either missiles or the blade (or your default gun).
Defeating Ironhead without getting hurt will also earn you the “Here’s Johnny!” achievement.
If you obtained the iron bond by taking the save Curly path (see the I’ve Got Your Backachievement), and traded back your mimiga mask for the booster 2.0, you’ll enter a different version of the final cave. The cave consists of having to use your booster in tricky ways (to avoid hitting spikes) while getting past a few enemies. Near the end of the cave, you’ll have to fight the red ogre. Just use your super missile or spur and you can beat him in 10 seconds. Be careful of his jump attacks though.
After you get through the final cave and head to the right, you’ll now have to confront everybody’s favorite Cave Story witch, Misery. She’ll teleport across the area and will summon 2-4 dark balls that will orbit her. Aim at the right time with your spur or nemesis/sword to see the best results (save your missiles for later). She’ll also summon bats which can easily be destroyed, and blocks that can be appear above you (in that case, use your booster to quickly dodge it). When she summons three black balls that come towards you, use your booster to quickly go below them, so they’ll fire lightning bolts and you won’t be hit (otherwise they’ll keep following you).
After Misery, you’ll now have to fight the Doctor. He’ll fire red orbiting beams that can easily be dodged by boosting upwards, and he’ll also go in mid-air and release a burst of red beams (in that case, get as far away from him as possible). Aside from that, just shoot him with whatever, although be aware of his red crystal that orbits around him, which will block all attacks that hit it.
After you beat the Doctor’s first form, he won’t be able to control the full power of the red crystal and will transform into the Muscle Doctor. He’ll charge at you, so be ready to use your booster. He’ll also unleash a crap ton of bats at one time, which is why it’s helpful to have the spur with you. Fire at him just like with the normal Doctor, and by the time you know it, the Doctor will be dead forever!
…Or is he? Head up after you beat the Muscle Doctor, and you’ll now have to fight the Undead Core. Fighting him is pretty much the same as the normal Core fight, although there’s no annoying water, and now Sue and Misery will attack you. When dealing with Sue and Misery, Just shoot at them with the spur. Misery will release a whole bunch of enemies every once in a while, which can also be defeated with one hit with the spur, and is helpful for gaining health. Aside from that, just fire missiles at the Core as usual (though be careful of his giant attacks that he’ll unleash when his mouth is open).
Get the normal or best ending (bad ending won’t count) while playing on easy mode. The only real main difference from easy and normal mode is that damage taken is halved.
Get the normal or best ending while playing on hard mode. It’s worth noting that to get the normal ending, you don’t need to do any of “save Curly” sections (fighting the core, ballos, etc.). Main differences between normal and hard mode:
- No life capsules (excluding the one that the dog gives you at the plantation, which means that you only have 3 HP for the majority of the game).
- Missile launcher can not be obtained
See “Wind Fortress S-Rank” for more information.
In the reservoir in Mimiga Village (where you found the silver locket at the start of the game), there is an orange fish. To get this achievement, you need to beat the game without killing it.
After you get the missile launcher, you can start finding upgrades for it that increases the amount of missiles it can hold. Here are all of the locations:
1.) Bushlands: Head to the right of the save room door in the main area, and hop onto the platforms to the right to find the upgrade in a chest.
2.) Bushlands: Get up to the door pictured in the first screenshot via one of the fans, and you’ll find a chest with an upgrade (when you open it you’ll have to fight a rabid mimiga).
3.) Egg Corridor?: Under where egg #12 used to be.
4.) Egg Corridor?: Where the egg observation room used to be (when you open the chest you’ll have to fight the twin dragons).
When you get the little man (see above), take him back to his home at the Outer Wall and you’ll instantly get this achievement.
Life capsules are items found in the game that raise your health. There are 11 life capsules, and they can not be found on hard difficulty.
For all of the life capsule locations, check out my life capsule guide.
You’ll easily get this by the time you finish the game. Just keep attacking every enemy you see and you’ll get this in no time (I got this while in the Labyrinth).
(For some reason this achievement doesn’t have a picture)
Play Cave Story+ around the Christmas holidays. Will unlock if played on either Christmas Eve (December 24th) or Christmas Day (December 25th).
