Blizzard Mountain is the first big Forza Horizon 3 expansion - all the details

Forza Horizon 3's first expansion has been fully detailed.

Microsoft has announced the name and other details about the first big Forza Horizon 3 add-on. It's called Blizzard Mountain, and it adds the snowy alpine mountains to the game, for the first time.

Blizzard Mountain comes with eight new vehicles (including a new Barn Find) as well as new race events designed specifically for the DLC. There are over 50 events and challenges, all part of the new King of the Mountain campaign.

Hill Climb, Descent, and Blizzard race events are among the new race types, in addition to new Bucket List, Blueprint, and Rival events. You'll be able to earn 28 new achievements worth 500 points. In typical Horizon fashion, you'll also have more bonus board to smash and beauty spots to explore.

If you prefer to use your existing vehicles to explore the new DLC, you'll be able to upgrade their tyres to snow variants.

Here's a list of the new vehicles:

• 2016 Ford GYMKHANA 9 Focus RS RX
• 1965 Ford F-100 Flareside Abatti Racing Trophy Truck
• 1975 Lancia Stratos HF Group 4
• 1985 Lancia Delta S4 Group B
• 2016 Nissan Titan Warrior Concept
• 2016 RJ Anderson #37 Polaris RZR-Rockstar Energy Pro 2 Truck
• 2016 Subaru #199 WRX STI VT15r Rally Car

The expansion is part of the game's expansion pass, and will be available for sale separately - pricing for that has yet to be announced, however. It is not part of the Ultimate Edition, though you'll get a $10 discount on the expansion pass if you're an Ultimate Edition owner, provided you do so before the end of the year.

Blizzard Mountain is out December 13.
