• On level 1 “Factory”.
  
• When the psychologist calls us.
  
• We must hang up the call.
  
• Until he gets angry and gives us the achievement.

Bonus fact: The achievement refers to a band which released a song with the same name, The author of the achievement claims it's great, but to me it seemed very zzz.

You stopped a suicide. With a murder.

• In the corridor there is a statue.

Bonus fact: Ironically Josh Rose's character prefers to commit suicide rather than be killed for his crimes, canonically the main character “zero” kills him.

Complete a full run in Hard mode.

• We must play the game's hard mode.
  
• This mode contains new enemies in sections that don't appear.
  
• This mode only activates the action and omits dialogue or cutscenes.

Hard mode is unlocked when you complete the game's campaign for the first time.



Note: It doesn't matter if you die or take too long; the only thing the achievement requires is to complete it.

Tip: Learn the enemy attack patterns.

Achieve a total rank of gold or higher in a full speedrun

• We must earn the gold medal in Speed Run mode.
  
• For this mode, we must complete the game in the shortest time possible.

Note: Each level will give you a specific medal: Platinum, Gold, Silver, and Bronze.
Each level has its own individual medal and a time limit.
For the achievement, the game averages the total time to give you the medal.

So it doesn't matter if you have silver medals in a level; the important thing is the total time for the entire speedrun.

Tip: The best piece of advice I can give you is to practice each level before starting.

Time to earn a medal: 13-19 minutes.

You can pause the game and the time will not advance, so you can plan your next move or if you need to rest.
