Three parts of Forza Horizon 6 change how a week feels: the season clock, the places you build alone, and Horizon CoLab, where friends build together. Read one, then jump to a short guide or send the desk a question if a patch moved a button.

Foliage, crops, weather, and the sound bed all shift, more sharply than they did in Mexico. The alpine belt is the exception: snow tyres work there in any season, including a bright summer playlist week.

You can dress a whole garage as a showroom and build the Estate directly in the open world. Both are solo. Friends can visit, and you can download a garage layout someone else shared. Do not expect a co-op hammer here.

EventLab building goes multiplayer. Up to twelve players can shape a spot in Japan together. That is the co-op build. Garages and the Estate stay single-player, which is worth knowing before you invite a full convoy.
