Achievements can generally be grouped into six categories.

These are for performing an activity during regular gameplay; rather than measuring performance for a whole level these are shorter one-off accomplishments.



Wonderful!

Aerial absorption bonuses are given for absorbing multiple enemies in one jump; you'll often hear GOOD! (2 enemies in one jump) or GREAT! (3 enemies).

WONDERFUL! is the last of these and is given for absorbing 5 enemies in one jump. It is available in a few places, the first of which is the last part of the combat section in the opening stage. If you destabilise all the (name)s first you can jump and dash through them all in one go.

Beefed Up

As the icon indicates this requires holding all 3 passive boosts as well as a useable Xel Recovery at the same time.

This achievement should arrive naturally when moving through a level with diverse enemy types quickly. When trying to get it manually, good locations to find these are the start of the power plant and early in the final level.

Everlasting Love for My Boost

This requires a period of 60 seconds to pass in which you have a passive boost active. Holding a Xel Recovery item for a minute does not count.

This is easy to force near the end of the opening stage: After the combat section when absorbing the first (), there are multiple () enemies. Starting with the red boost, simply wait until each boost is about to expire before absorbing an () and the achievement will unlock after 2 ()s.

Sie das Ziel, ich der Jäger

This achievement is a more complicated version of Wonderful! because it is not enough for the five enemies to be destabilised in advance. Instead you have to absorb each of the 5 enemies before destabilising the next, which means alternating between fighting and dashing.

This limits when the achievement can be earned because there are not many places in the game where there are five enemies you can alternate in this manner. Some places where it is possible are the power plant (a descending corridor), the radio tower (during the large wind ascent) and the final stage (during the long wind section).

Aerodynamic

This is designed for a specific part of the radio tower level; shortly before the boss is a large ascent section with a constant upwards draft that causes you to ascend while dashing. Dashing to ascend to the top of this section without touch anything will unlock the achievement towards the top.

Smooth dive

This may also be designed for a specific part; early in the water works bureau there is a long water descent section whose latter part is also a spike descent that can be avoided by taking a hidden path to the right.

Starting from the top of this descent and taking the spike path causes the achievement to unlock if nothing is touched during the descent. It is possible to fall just as far by taking the hidden path and not touching the floor before continuing to descend but this does not appear to unlock it.

It is also possible to unlock immediately following the Aerodynamic achievement, by jumping back down after reaching the top. It appears dashing during this descent will reset the descend counter (since Beck will momentarily ascend) so this would need to be done without dashing.

Every boss in the game has two FINE PLAY! bonuses that can be unlocked for performing specific feats.


Opening Boss

1. During the missile attack, destroying all three missiles quickly.
   
2. Absorbing the boss during its rolling charge attack.

Mighty number conditions to be listed after.

Prison Boss

1. Avoiding all of its blinding shot attack.
   
2. Happens automatically when the boss swallows a ().

Robot Factory Boss

1. Destroying its projectile arms.
   
2. During the missile attack, destroying 16 missiles.

Last Boss

1. Avoiding all of the first form's yellow devil attack.
   
2. Absorbing all four sections of the second form in one dash.

Three of the technical bonuses in the game are awarded at specific points during levels; these achievements are unlocked by earning every instance of each of these bonuses.

Mighty Amazing
Mighty Survivor
Mighty Sprinter

Mighty Amazing

This is the easiest one as there are only six AMAZING! bonuses in the entire game and most involve branching paths:

1. Water Works Bureau: Survive the underwater spike descent.
   
2. Mine: Successfully take the short branch with health pickups.
   
3. Military Base: After the branching path, avoid the mine at the bottom of the drop.
   
4. Radio Tower: The long jump section (elaborate).
   
5. Prison: The branching path at the first (big enemy).
   
6. Robot Factory: The branching path.

Mighty Survivor

For every QUICK CLEAR! and NICE CLEAR! bonus.

QUICK CLEAR! is given for completing each combat section quickly. These are found in:

NICE CLEAR! is given for absorbing enough of the optional enemies in specific sections:

Mighty Sprinter

For every SPRINTER! bonus. This is the only one that needs every level as each have multiple sprint sections:

Automatically unlocked upon completion of a stage if the total score you have earned passes a threshold:

Mighty Collector
Mighty Hoarder
Mighty Millionaire

This is not a simple total of the highest score of each completed level (which is what is displayed in the file select screen). Instead, every time a level is completed the score is added to a hidden counter. This means you can repeat the opening stage until they all unlock.

These achievements should unlock naturally, and will do so faster with higher scores. It will take 35 stages if you average 30,000 points per stage, but only 15 if you can average 70,000. So ensuring you always get the highest Combos bonus (20,000 points) in particular is worthwhile here.

These require beating the entire game from a new save file with certain conditions met.


The game checks for each of these individually, so if you complete the game on NORMAL difficulty within 120 minutes you would unlock both Super Fighting Robot and Cleared Story (Fast).

You can unlock both speed run achievements at the same time (by completing the game in under 60 minutes) but this does not work for the difficulty achievements: Completing the game on HYPER will not unlock the HARD difficulty one.

For Legendary Peacekeeper, restarting means starting a stage more than once. This means selecting Restart in a stage after getting a game over, or leaving a stage and returning to it later.

For Mighty Anniversary, the game checks your local date setting at the point when the final boss is defeated. If this is the 9th of any month, it unlocks the achievement. Be wary of changing your system date to cheat this as your Steam time stamp will still show the real date as not being the 9th.

This section uniquely only has one achievement.


This seems to track per save file which also excludes game overs shown for failing challenges in EX Mode.

Separate to the main game, three achievements are found in the EX Mode instead:


Boss Rush requires a little skill to survive. Any player who is good enough to complete it at all should have done so in under 20 minutes so usually those achievements will unlock together.

The Solo challenges in EX Mode are mostly unique little tasks that explain gameplay mechanics and nuances of the boss abilities. But the rest are no-death challenges which is where the difficulty is: Challenge 36 in particular arguably makes this the hardest achievement in the game because it requires the entire game to be cleared without dying once.
