Microsoft Corporation tried to acquire a publisher engaged in mobile games. Mention of this is in the report of the British regulator, which is dedicated to the deal between Microsoft and Activision Blizzard.
It is unknown when and which publisher Microsoft wanted to buy. This data was cut from the report.
Judging by the document, Microsoft planned to use this purchase to get content that it could use to promote the Xbox mobile store that has not yet been opened. The fact that Microsoft is working on such a store became known in October 2022 from another report of the British regulator.
