Spotlight
A great game I know which would work really well for an event would be a game called 'Spotlight'. This is a game where you have one or a set number of 'seekers' who have flashlights on their guns to try and find the 'hiders'.
The Moderators or Administrators running the event will choose someone or a group of people to be the seekers. I would recommend two people to be seekers, everyone else will be hiders. Players will be teleported to an area, this could be a town or maybe old rebel island ect. Boundaries will be drawn on the map and if you leave the area you'll get one warning to return and if they don't they get killed by a Mod or an Admin.
Gear
Seekers
Seekers will have any clothing of their choice or clothing that a Mod will assign them plus a high vis vest on so hiders can easily spot them. Seekers will have a gun, maybe a PDW or Protector with a RCO plus a flashlight. Seekers must NOT have night vision goggles on and this will be the Moderator's responsibility to make sure no one is bringing any gear in which is not allowed or will give them an unfair advantage, this can easily be done by a Mod killing the player and then assigning them gear from a crate. Once the seekers have their clothing and gun ready then they will wait until a Mod or Admin tells them the game has started.
Hiders
Hiders can wear any clothing of their choice but they must NOT have any vest or helmet on. Whether or not they have night vision goggles will be up to the Mod running the event. Hiders will NOT have a weapon on them but they can have the basics such as food and water. They must NOT have anything on them that can harm other players, spike strips, guns ect.
What will happen
Once both hiders and seekers have gear sorted out and are ready to go, there will be a timer for hiders to go hide. The timer will be set for 5 or 10 minutes to give hiders a good amount of time to go and find a hiding spot. Once the timer has run out the seekers will be released into the marked area where the hiders are hiding. When it comes to what will happen when seekers find the hiders can be one of two options, either they must kill the hiders, or once they spot the hider they must call out to them they are found. When they call out they must state what the hider is wearing and must state the spot they see the hider hiding, this is too prevent seekers from baiting hiders to come out by just yelling out randomly that they have found someone. Once they spot the hider and they have come out, seekers will put the hider in zipties and take them back to a designated 'Prison'. Where the captured hider must sit until the game is over. Other hiders can come and break out their friend by running into the prison and tapping the captured hider or hiders. Once they are tapped all hiders that were captured can go back into the game and hide. This why 2 or maybe 3 seekers would be good because then 2 seekers can go out and find hiders, and 1 seeker can guard the prison. If the prison guard sees someone trying to get to the prison to break out their friends, the prison guard may shoot the hider attempting to break out prisoners.
Time Limit
The game will have a 20 or 30 minute limit and can end quicker if the seekers find all the hiders. Another option is too break up the players into maybe 3 or 2 different groups. One group could go to a town and the other group could go some place like old rebel island. Each group would have a Mod or Admin controlling the game.
Would be great to see this game used for an event and thanks for asking for our suggestions and ideas?
