Game developer Rockstar confirmed the move in a recent Q&A posted via its website.
“For Xbox 360, Grand Theft Auto V will ship on two discs; Disc 1 will be used for a one-time mandatory install and Disc 2 will be used to play the game. After the install, players will be able to enjoy both Grand Theft Auto V and Grand Theft Auto Online without any need to switch discs,” explained the company.
Rockstar also noted that the install would require an “external 16GB USB flash drive with at least 8 GB of free space.”
Meanwhile, the PlayStation 3 version will only require one disc. GTA 5 is set to be released for both consoles on September 17th.
