The Xbox 360 version of Grand Theft Auto 5 requires a mandatory install on both PS3 and Xbox 360 and will ship on two discs on the latter.
"Grand Theft Auto V is the largest and most ambitious game we have yet created, and takes full advantage of every ounce of processing power available in the current generation of consoles," said Rockstar in a Q&A published this today.
"In order to provide the best possible experience for such a massive and detailed world, the game will have installation requirements on both Xbox 360 and PlayStation 3 systems.
"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."
You'll need at least 8GB of free space in order to install the game on Xbox 360 and PS3.
"A new USB flash drive is recommended to ensure optimum performance," says the Rockstar Q&A.
GTA 5 is released on Xbox 360 and PlayStation 3 on September 17, 2013. You can pre-order below.
