Hello everyone!
I got an xbox one s with FH4 included this summer and decided to put in a legitimate effort now to work towards all the achievements (in the base game only at the moment, no dlc).
I’m still trying to get an understanding of how the game works exactly but from what I know there are two achievements that have to be completed in multi-player (are there others?):
- Jolly Cooperation (Complete 5 Horizon Life Co-op Races.)
- Human After All (Complete 5 PvP Races.)
Of course I’m happy to race with one or more of you towards the other achievements as well. 
My Gamertag is SpecOfOli (obviously) and I don’t have a mic so will settle for messaging via the xbox app I use on my phone. This weekend and most evenings this week and next should work (Central European Time). Otherwise I’m happy to accept/send friend requests and spontaneously find time to drive.
Thanks!
