As many people have speculated it looks like that Amazon Games will be hitting Luna + with New World the first title to do so. Twitter user and all round good guy Ashes2Ashes has revealed that New World has shown up under Luna + but is not playable as yet. Luna does not have multiplayer as yet, as it is in early access, but with this game making an appearance this will require multiplayer access and quite likely cross platform multiplayer with PC.
This is an Amazon first party title and this could indicate that Luna + will be going down the Xbox Game Pass Ultimate route. By this I mean first party games will go straight into Luna +. Depending on the amount of games and studios this could make Luna + very compelling offering.
