The players’ verdict
Couples, friends and solo detectives.
Here’s what players thought.
Fake facebook was sick, super fun, satisfying ending. Heads up would recommend one person on social media while the other goes through physical evidence.
We loved it (it was a little harder than expected). We would have liked to have more story about what happened at the club and more CCTV on the street. We'll definitely playing another one soon!
10/10 cant wait!!!!!
