In one announcement that no one was expecting, Microsoft announced a crossover between Forza Horizon 4 and Lego in its E3 press conference today. We don’t have all the details yet, but we do know that a new expansion called Lego Speed Champions will launch June 13, bringing Lego cars into the classic Forza franchise.

The gameplay trailer showed at the conference included the track “Everything is Awesome” from The Lego Movie, so we may be seeing more music from that soundtrack in the game, or original music from some of the artists who worked on it.

The trailer showed Lego cars driven by minifigs through an all-new environment built of Lego blocks. As the vehicles careened through these new tracks, we even saw them tearing up pieces of the environment. What we want to know is whether the Lego versions of cars will be destructible. It’s not standard for the series, but it seems like a core part of playing with Lego.

Forza Horizon 4: Lego Speed Champions will be available for $19.99 if purchased on its own, and it’s coming to the game in Forza’s Expansion Bundle and Ultimate Edition.
