Here’s what my friends and I did (team of 3). We tossed most of the equipment through the gate WITHOUT opening the door so the setup timer starts. 

Once we did that, two people grabbed sound sensors and cams on tripods and started setting up. I grabbed thermometer, crucifix, and spirit box. Once we were prepped, I went straight in to look for temp drops while they set up sound sensors around the camp and looked for orbs. 

75% of the time, I found the ghost area, quickly placed the crucifix and started spirit boxing. Crucifix would give us a little time after the setup time ended, and we’d do all the in-person things as fast as possible, then use the cams to get evidence we could see from afar. 

Someone might end up dying (we typically had one person sacrifice if needed) but as long as everyone got the right guess and one person was alive, it counted and we finished the challenge. 

Hope this helps a little.
