Sea of Thieves is arguably Microsoft's hottest exclusive Xbox game in the last few years and now you can get it free when you buy an Xbox One X or even the older Xbox One S.
If you're in the US, you can also pick a second free game to add to your bundle from a choice of seven titles.
If you're not especially bothered about the 4K loveliness that the Xbox One X provides, then you can still get some great deals on the older Xbox One S bundled in with a copy of Sea of Thieves.
In the UK you can get a 1TB Xbox One S with Sea of Thieves for just £249.99 at both Microsoft and Amazon. Update: Tesco has an even better UK deal at just £229.
The same bundle in the US is going for $299.99 at Microsoft AND you get to choose an additional free game from a choice of seven, including Assassin's Creed: The Ezio Collection and Tom Clancy's The Division.
