In the Name of the Tsar Price
If you'd prefer to buy the game's DLC on a case-by-case basis, you'll have to shell out $15 for the standalone version of this DLC.
This price is confirmed with the standalone In the Name of the Tsar release. Microsoft, Sony, and others are all charging $15.
If you think you'll be playing Battlefield 1 for a year or more, it might be worth it to invest in the Premium Pass.
The Premium Pass will save you $10 on all four pieces of DLC and it comes with some nice perks including, again, two weeks early access to In the Name of the Tsar.
We expect the next two DLC's to command a $15 price point as well.
