* Required. Locked until finding Tessa's ID card on Day 4.
** Not required. Corrupted until solving all puzzles in the developer options (see 'Hacker').

Patience
Wait until the screen saver icon hits the corner exactly.
Day 4


In the main control room, interact with the console (right) and wait until the screen saver icon hits the upper right corner (it might not be perfect hit, there's a threshold for the achievement):

Listen Carefully
Find access to the station's developer options.
Day 4


In the main control room, interact with the console (right) and click three times on the I.M.C logo.

Hacker
Unlock all levels of developer options.
Day 4


In the main control room, get access to the station's developer options (see achievement 'Listen Carefully'). Then, solve all five optional number-guessing puzzles. Tips:

• Use the first guesses to determine the included digits.
  
• Remember that digits could be included more than once.
  
• Note the pattern on the right, it's either a stairs, pyramid, upside-down pyramid or zigzag.

Stairs → The sequence is increasing from left to right.
Pyramid → The sequence increases, then it decreases.
Upside-down Pyramid: The sequence decreases, then it increases.
Zigzag → The sequence increases, then it decreases, then it increases again.

Note that digits can be repeated without breaking the pattern! For instance, the sequence:

1-1-1-1-1-1

applies to all patterns - the stairs, pyramid, upside-down pyramid, and even the zigzag.

Connoisseur
Activate all Holo Records, examine all planetary locations, look at every print option.
Day 4


The planetary locations will become inaccessible after finding the correct mission location. However, they can be accessed again towards the end of the day, before entering the rover.

Recycling
Melt the broken axle mounting and use it in the 3D printer.
Day 4

Gram Accurate!
Create the axle mounting with the perfect material mix. Accurate to the gram!
Day 4


The achievements 'Recycling' and 'Gram Accurate!' can be combined by following these steps:

Use the broken axle mounting on the oven in the laboratory, then place the recycled block in the 3D printer ('Recycling'). Next, mix the following ore parts by using the scale in the laboratory:

72 g Metal Mix
Majalt: 3x nuts (24 g).
Guffinium: 8 g, 9 g, 14 g, and 17 g ore parts (48 g).



Use the 72 g metal mix on the oven in the laboratory to obtain the 72 g alloy. Add the 72 g alloy to the 430 g melted axle mounting block in the 3D printer, then print the axis ('Gram Accurate!').

Curious... although unsettling.

Fact Checker
Give 10 correct reactions and statements in a row in the meeting.
