Those looking to play Halo 5: Guardians when it launches Oct. 27 — particularly those who have a downloadable copy — may have some planning to do. The game's installation size requires "up to 60 GB," according to packaged versions already circulating.

That would make it one of the heftiest console games out there, and it presents issues for anyone with a standard 500 GB Xbox One and a bunch of games already installed on it — to say nothing of the time it'll take to pull down all the components of the downloadable version.

This is not a small deal; those who ponied up for the $249.99 Limited Collector's Edition of the game were upset to learn the game itself was a code for the downloadable version. Microsoft relented and offered the option to claim a disc version of the game from Oct. 20 until Nov. 1.

Halo 5: Guardians is also bundled with a 1 TB special edition Xbox One, though the game included is a code for the downloadable edition. The product page for Halo 5: Guardians on the Xbox One Marketplace does not list a file size.
