Sniper Elite 3 has a whopping 10GB day one patch sitting waiting for those who buy the game on Xbox One.
That mandatory install was initially going to be be 21GB, but 14GB of it will be replaced by the day one patch, while the full install size is now cut to around 19GB.
"The main part of the update is to sync data between the game's retail discs and the Xbox Live digital download edition of the game. In the several weeks between sending the code off to manufacture and release, rather than sit around or take a break, we've continued to work on the game, making improvements and optimisations," Explained Rebellion.
"We've also begun work on multiplayer DLC and a small part of this update is to introduce a compatibility pack. This is standard for any game that adds DLC - it's just to make sure everyone can have the same multiplayer experience whether they own DLC or not.
"While we understand gamers will be frustrated at the wait, the good news is that the update will actually reduce the size of the game's total install footprint on their hard drive, and reduce the size of future patches significantly.
"It's part of this ongoing optimisation process that's enabled Sniper Elite 3 to perform well at a native 1080p on both Xbox One and PS4. We appreciate everyone's patience and we firmly believe Sniper Elite 3 will be worth the wait!"
Day one patches will also apply to PlayStation 4, PlayStation 3 and Xbox 360, but they will be much smaller.
