Sniper Elite 3 on Xbox One requires a 16 GB day one patch.

The retail version of Rebellion’s Sniper Elite 3 on Xbox One will have a big patch waiting for players attempting to play the game, a 16 GB patch to repair data sync issues between the retail and downloadable versions of the game and ensures DLC compatibility in its multiplayer modes. The patch is one of the biggest in recent times, outshining the 13 GB Dead Rising 3 patch released shortly after the game’s release.

The patch will only affect Retail copies of the game (i.e. Disk based), as the Xbox Marketplace digital copy will already have the patch included. The PS4, PS3, and Xbox 360 versions will see a patch but it will be significantly smaller.
