Activision have announced that anyone who purchases a physical copy of Call of Duty: Black Ops 4 will be looking at a 50GB download of the game's day one patch. As for the digital downloads, the day one version of weighs in at 55GB.
The company said that you'll need to instal the patch in full to play Call of Duty: Black Ops 4's multiplayer, zombies and specialist headquarters. The actual installation footprint is 55GB though, just like the digital version.
Note however that Blackout, Black Ops 4's new battle royale mode is playable once the game is at 30 per cent of the installation process. Activision say this is around the 16-20GB mark and it's a pretty clever way to make sure players have something to do until the entire thing is up and running.
There was talk of Call of Duty: Black Ops 4 the 100GB mark, as PlayStation box art suggested a 100GB requirement. While that doesn't seem to be the case at the moment, Activision does recommend 112GB of free hard drive space for an "optimized download experience".
Of course, that doesn't mean that Call of Duty: Black Ops 4 won't be crammed full of skins or whatever cosmetics Treyarch have in store, which could easily multiply this number. After all, SuperData's reports estimate the battle royale genre to rake in $12.6 billion in revenue in 2018 and $20 billion in 2019, with Blackout expected to drive a significant share of those.
Treyarch have made sure to extend an olive branch to PC players as well, starting with the that touts mouse and keyboard support as if the original Call of Duty never had them. They did say they'll raise the FPS cap to 120 at launch, which is a welcome change from the 90 FPS cap during Blackout's beta, and further to 144 FPS once the game is stable for everyone.
Call of Duty: Black Ops 4 launches on 12 October 2018 for PC, PlayStation 4 and Xbox One.
