Additions :

• Signs around the maps to indicate major rooms and rooms of interest
• Label on map indicating the spawn/exfil location of robbers

Changes :

• Guard peripheral vision reduced
• Guard peripheral spot chance reduced
  
• Guard footsteps are louder
• Guard patrol walk speed slower
• Added a Zapper to the (now spare tools) closet on Intercept

Plans for future update :

• add more small sub puzzles to levels, currently they are designed with multiplayer pvp in mind but this can be tweaked to include some interesting puzzles
