Welcome to Rocket League Disadvantages, the place where lower leveled players can beat higher leveled players. You've seen those videos of "6 Plats vs. 1 Grand Champ". And this map is built around that premise!
Everyone who's on Orange will have a ton of disadvantages and everyone on Blue just plays normally. There are 10 Unique Events that can happen to Orange that will happen every 5 or so seconds. There is an extremely rare occurrence where something might not happen for some reason. Just rejoin teams and it'll fix itself. If you are the same rank, offset the teams. So 3v1 with 3 on orange or 2v1 with 2 on Orange etc.
Mutators: This is a standard map, but disabling demoes makes gameplay a lot more fun and a lot smoother. Don't worry I'll demo Orange plenty ;)
