I don't see there being a problem with a guard explaining a special day (Hunger Games, Hide and Seek or Warday) under the notion that they don't have a microphone. These days are rather straight forward and to the point and are not considered customized special days.
Hunger Games
- Prisoners have 45 seconds to find weapons and a safe place before they must kill other prisoners until only two are remaining for last request.
- Prisoners must not delay the round by camping and they can team up with other prisoners but they can betray each other at any point.
- During this special day, Guards cannot be hurt, and must not hurt prisoners or assist prisoners in any way (e.g. blocking bullets, dropping guns, telling them where other prisoners are, using anything to kill or injure them ...etc).
Custom Hunger Games is not allowed (i.e. ordering prisoners into a closed off location before activating HG).
Hide and Seek
- Guards must stay in armory and cannot peak out of armory or into vents until it is expansion time.
- Guards must kill all prisoners with the exception of the last two prisoners that reach last request.
Warday
- Warday automatically expands at 6:00 or after if specified by the warden.
- Guards must not leave the warday zone until it has been expanded (unless Last CT), and they must not kill outside the warday zone unless they are on-route & were attacked first (self-defense).
- Prisoners must actively pursue the Guards and you cannot !lr on a warday.
As for a "Freeday" this would be considered a customized special day as there are many diverse parameters that can be given. In the event that a CT becomes Warden and activates this day without a microphone, I feel as though basic rules would be implied; such as no default knifing distance, red is dead and no other restrictions or exceptions.
