Metro Exodus released on the Epic Games Store on February 15 with a timed exclusivity deal, because of this it was pulled from Steam. The exclusivity was signed for one year, which means if you want to get it from anywhere besides the Epic Games Store, let’s say Steam, you have to wait until February 15th, 2020.
Now, not even a full four months since the release, it showed up on the Windows Store set to release at the end of the week. The exact details of the exclusivity deal are unknown, so there might be something that explains this inconsistency.
The listing for Metro Exodus on the Windows Store might just be a placeholder, but if it’s not, PC gamers that prefer Steam probably won’t be happy about it. Currently, there are no changes on the Steam page for Metro Exodus or anything that even hints a release before 2020.
June 9 sounds like a believable date since Microsoft is holding its E3 2019 press conference on the same day. They might announce the release and explain why is it coming so soon during the conference. An interesting possibility is that it will comes as part of the Xbox Game Pass for Windows 10.
