The #MillenialMonster photo challenge in Forza Horizon 6 requires participants to capture an image of a rally monster car manufactured in the 2000s. This can be a challenge given the vast selection of vehicles available in the game, particularly for players who may not be intimately familiar with the rally car subgenre.
To complete the challenge, players can use the 2007 Peugeot 207 Super 2000, a vehicle that is typically acquired by completing the pink wristband event in the game's campaign. This car fits the criteria of being a rally monster from the specified decade.
For players who do not own the Peugeot or have not yet reached that point in the campaign, the Autoshow offers a single purchasable option that meets the requirements: the 2001 Ford #4 Ford Focus RSS. This vehicle is available for 415,000 credits. Before making a purchase, it is advisable for players to check their existing vehicle inventory to ensure they do not already own it. This can be done by accessing the car list, sorting the vehicles by year, and filtering by the rally monster car type.
Once a qualifying vehicle is in possession, players simply need to enter it and take a photograph to successfully complete the #MillenialMonster challenge. Doing so rewards players with the "You're a MONSTER!" Forza Link chat message.
