Capture The Flag
Each of these characters will use their knowledge and tech to build a fortress with an advance security system. And they will have one year to complete it and to prep themselves. The way to win this battle is to capture the most flags. Each fortress will have one flag protected by its security system. And all contestants will start off all at once. If more than one contestant reaches the same fortress, they are permitted to use whatever means necessary to capture the flag in that fortress (without killing). But if someone captures a flag, no one is permitted to try and take it once they already have it. And they must move on to the next one. They have 24 hours to capture the flags.
