These missions are remakes of Gerald's missions from GTA ONLINE.

If you've played Grand Theft Auto V: ONLINE, then you definitely know who Gerald is. As the character who helped many players start their criminal careers, he played a vital role in the game's narrative. Being the third character introduced in Grand Theft Auto 5: ONLINE, after Lamar and the protagonist, I am confident that it's time to celebrate Gerald's missions by creating remakes of them with DYOM. These missions will be challenging, but definitely worth your time. So, gear up and get ready to experience the world of Grand Theft Auto V: ONLINE like never before (in a different game)!
