Metal Unit: All Achievements Guide

This is an achievement guide for Metal Unit. Most achievements will unlock naturally as you play. Information will be provided to explain how to get everything. You’ll need 4 playthroughs to get all achievements: New Game, (New Game+1 and +2), Challenge 4: Hardcore Mode (1 life). Challenges 1, 2, 3 and 5 are not required for achievements. The initial playthrough unlocks the NG+/Hardcore/Challenge options. Hardcore uses a separate save slot, so your original save data is not lost on death.

There may be spoilers depending on where you look. Images used are from in game screenshots.

Here’s some basic information about how the game plays.

Progression:

Complete the tutorial level/Episode 1’s boss of Stone King to save your initial progress. Afterwards you’ll be in the Sun Tail Base map. Game progress is saved every time you return here. If you choose “Return to base” from the menu during a mission, it counts as a death. You’ll lose your inventory and coins, but you’ll gain CC based on your performance. Any items you found will be unlocked for deployment from your armory, though you can only take 1 of each item type per group. These items can earn mastery experience but cannot be sold for coins, used for synthesis or used for crafting. Initially you’ll only have access to common tier items. Gain mastery experience to unlock rare, epic and legendary items for use. Master items by equipping them and killing enemies.

CC (Crystal Cores) are mainly used for permanent character upgrade progression. You’ll earn CC from killing bosses, opening random chests and dying during a run. They can also be used as currency in Sun Tail Base to buy items.

Coins are used to buy items/trade during a dungeon. Shopkeepers carry 4 items. Coins are earned from defeating enemies or selling items.

Synthesis combines two items to make a new random item. The quality of the input ingredients affects the outcome. Two common tier items have a high chance of producing a common item, with a low chance of producing a rare item instead. Potions are an exception. Combine two potions to get a higher quality potion!

Crafting uses various specific items to produce specific items. Recipes are unlocked as you progress through the story. Sometimes it may be quicker to craft a new item instead of waiting around for it to randomly drop/synthesis. A few recipes convert 2x common items into 1x rare (for example: two pebbles into one better pebble).

Dungeons consists of 15 map areas and 1 boss. There can be rest areas as well to buy/sell/synthesis/craft. You can choose to rest for full HP, or take on a bonus room for a treasure chest. Dungeon maps can be random. Some maps may contain chests or secret areas. The minimap can reveal hidden areas. Sometimes you may need to explore higher up in a map to find hidden exits or chests. Hidden exits often contain bonus loot/enemies/puzzles.

Dodging is your tool for survival. If you can’t avoid an attack, you can dash right into it to negate it completely with good timing. Most attacks can be nullified this way. The telltale !!! warning attacks should be avoided completely.

Editor’s Notes
To do:
[currently in challenge run (1/2/3) on Episode 4. Need to finish to access more information]
Check for typos/formatting.
Add a few missing boss drops. Add in Episode 5 first boss, Green Portal boss attacks/name.
Finish crafting recipe list with names.
Make Ancient Temple map more pretty. I forgot about a couple of rooms as I was making it, leading to space issues.
Add solution for Lights Out puzzle, the 3×3 3-color one. Need to find it again in a run.

If there’s anything you’d like me to add, let me know and I’ll see about working on it.

==Tutorial/Episode 1==
From game start to first boss is fairly easy and straightforward. There are a lot of HP potions to find, including some in hidden areas on the map. Look at the minimap to easily reveal these areas for bonus items.==Stone King==
Stomps to make rocks jut up from the ground in a line.
Tosses blue orbs around him.
Sprays a line of orbs that spins slightly at a medium distance.
Can teleport (does not deal damage). Can combo with ground stomp.

After defeating Stone King you’ll be in the Sun Tail Base map. You begin in Joanna’s room. The first room has the VR Console to practice using items on enemies. Enter it, pick up any weapon and equip it. Head to the lower right and attack the training dummy for an achievement. Exit with any green door. The next room has the armory, set bonuses, skin changer and storage. The armory lets you take 1 of each item. The armory consists of pretty much every item/weapon you’ll find in your dungeon runs. As long as you’ve found something once, it’ll appear here for future use. You can master these items, they just can’t be sold for coins, used for synthesis or used for crafting.

The set bonus machine gives you a passive depending on which set you pick. Initially you only have Cadet unlocked, so you’ll start with bonus HP potions in your inventory if you die. The skin machine lets you change your player skin model which is cosmetic only. The storage area is found below. You can store items here that will be saved even if you die. These items can also be used for crafting during a run, saving you inventory space. You unlock more storage as you progress in the story.

In Sun Tail Base there are shops that require CC as currency. These shops are meant for late game when you no longer need CC to upgrade your character. Head to the right to find the mission portal. If you ignore it and go further right you’ll find the museum. There’s a chest inside for 2 CC. Double jump and dash to get up the cliff. Falcon’s Health Scan and Assault Mode upgrades are good early grabs. Health Scan shows enemy HP. Assault Mode gives you another item slot to equip things. Metal Unit’s Power of a Giant gives you access to many secret areas in Forestia. Pick that up when you can to get more treasures per run. Head to the portal to begin Forestia.

These challenges use a separate save slot but upgrade your original save slot with the rewards. So you can freely attempt Hardcore Mode without losing your original save data. There’s 5 challenges and you can activate as many at once as you want. You’ll begin the game starting at Episode 2. You can abandon your challenge progress to return to your normal playthrough by revisiting Yuna’s Room.

Here’s a list of the crafting recipes and the materials they require. You can safely store items for crafting purposes in your storage area in Joanna’s Room. Armory items cannot be used for crafting. You’ll need to find materials as you play and store them for later. For most recipe items it is possible to randomly synthesize them, but depending on your luck you may just want to craft a missing item instead.

The Temple entrance looks like this:
I made a rough map to visualize the layout of the Ancient Pyramid. Start at the green box on the left side. Explore all the rooms to find chests, enemies respawn and can drop Alien Part (common). These enemies don’t give Mastery Experience. There’s a player skin to be found going from door A>D>E>F. You’ll need Metal Unit: Power of a Giant. You can get away with not having the Cat Walk upgrade if you’re quick with dashing and make use of your double jump to hit the ice midway through the bridge.

Kill the Eye of the Ancient at the end of the temple area to get CC, pieces of the Guardian Set and an achievement.

This achievement requires you to find the secret area Forestria map that contains cherry blossoms, a merchant, Light Katana and an interaction object with a message. The message reads: “Don’t say anything. Forget about all sounds. Maybe then you will find the real treasure if you’re not looking for it.”

You need to hit the three statues in the map in order: Top right, bottom left, middle. After hitting them, a treasure will be revealed in the top left section of the map.

This contains the Broken Dragon Katana. Master the weapon. You’ll then need to craft the Dragon Katana. It requires #1029 Broken Dragon Katana, #6025, #6029. After you make the weapon, you’ll get the achievement.

In Joanna’s first room there is a VR console. Activate it to open the testing area for gear. Pick up any offensive item and equip it. Head to the lower right to find the training dummy. Simply attack it once for the achievement.
