For my Investigation instructions, I will leave out anything that doesn't advance the section. You should investigate everything just because it's fun, but I'll be leaving out flavor text.

If you’ve played an Ace Attorney game, you know what’s up. If not, here’s some tips

• The game is split into Investigation and Interrogation sections. In an Investigation, your goal is to gather information/evidence by investigating scenes and talking to suspects. Once you have sufficient evidence, you can review and dispute statements. When concluded, you’ll be moved to the Interrogation section. In an Interrogation, your goal is to dispute statements and answer questions
  
• Questioning during a statement will rarely open up a new opportunity to advance the case. It’s mainly for additional information or comedy. If you don’t see an obvious issue with a statement, try questioning to see if the information revealed in the question draws attention to issues with the statement.
  
• Cycling through a statement during an Interrogation will give you dialogue where the Justina and the detective give you a hint as to what you have to look for
  
• This game does not penalize you for incorrect answers. In fact, it will strike out bad guesses to help you keep track of what you tried
  
• The Case File has a tab for leads, a checklist of things to do during the investigation. It also has the detective's brief, a summary from the detective on case summarizing what they investigated, which is a good source for objective information. Additionally, a list of all statements, written line by line, is available
  
• If you've investigated everything and spoken to everyone in an investigation and still aren't progressing, you need to dispute someone's statement
  
• When you're looking over a statement, think of two thins: what do you believe truly happened in the case, and what do you think that, in that statement, contradicts the evidence? Remember, the goal is to dispute the statement
