In this mode, you play with five other people, split into Seekers and Hiders. The Seekers are tasked with locating the Hiders and remaining close to them, while the Hiders need to hide and then reach the End Zone when it's revealed.
Beyond this, there's plenty more to discover - as highlighted on the official Forza Horizon website.
"The time has come to grab your magnifying glass and get the hunting hat off the rack to uncover the secrets of Hidden Horizons! Your detective and hiding skills will be put to the test with the new Hide & Seek multiplayer mode."
Forza Motorsport has also received a bunch of improvements recently, including a new Spectate Mode in Private Multiplayer, a new Challenge Hub, and new weather options that can be selected in Free Play and Private Multiplayer.
Again, full details are available on the official Forza Motorsport website, and we'll also throw some trailers down below.
"In addition to the cars and events, we have two exciting features coming with this update: Spectate Mode, so you can race from start to podium and save a replay at the end, and Challenge Hub, which allows players to choose how they earn reward cars: either via the Featured Tour in Career as before, or by completing races in Featured Multiplayer. Moreover, Update 12 brings advancements to the Forza Race Regulations (FRR) AI Penalty System and customizable weather options for Free Play and Private Multiplayer."
