4. Transparency of systems 

We believe that players should never be confused about why they were spotted.

They need to know where it’s safe, and where it’s not on the level. Thus it should be clear how they are seen, heard, and tracked.

• alert states are visible and predictable so player always knows they’ve been spotted
• player’s visibility is communicated through visibility meter in HUD (more on that in the next post)
• noise level is communicated through noise meter in HUD  (more on that in the next post)
