Haven't touched the game since 4 landed, but I certainly will on February 8. The Final batch of Forzathon events will begin, and this time there are achievements to earn. Details below from the official site:
Final FH3 #Forzathon Events
Next week we’re introducing the final set of #Forzathon events into Forza Horizon 3. These events will go live on February 8 and, unlike previous #Forzathon events which rewarded cars, credits or XP in Forza Horizon 3, this final batch of events will award achievements, each worth 125 Gamerscore points. Each #Forzathon event/achievement (and subsequent Gamerscore reward) can only be earned once.
Here’s the list of events:
|#Forzathon Cleaning Up The Festival||Complete 1000 Races or Snowman Skills||125 GS|
|#Forzathon See You Horizon Boss||Complete 1500 Races or Kangaroo Skills||125 GS|
|#Forzathon The Final Tour||Complete 2000 Races or "Hot Wheels" Skills||125 GS|
|#Forzathon And Thanks For All The Drifts||Complete 2500 Races or Ultimate Skills||125 GS|
