Halo: Master Chief Collection needs a 20GB day-one patch

That’s no moon — it’s a gigantic update to a video game.

Microsoft is preparing to release Halo: Master Chief Collection on Nov. 11, but the disc you can buy that day won’t have everything that you need to fully enjoy some sci-fi first-person shooting. Instead, you’ll need to get online and download a 20GB patch that enables new features and “multiplayer content,” according to Microsoft (via Kotaku).
