According to reliable insider bilbill-kun, LEGO Horizon Adventures will be shown at the Summer Game Fest on June 7th. The game will be released immediately on PC and PlayStation 5 and will require linking a PSN account.
Unfortunately, the PC version will require a PlayStation Network account, so the project will not be available in 170 countries. The insider also noted that an in-game store could be added to LEGO Horizon Adventures.
Recently there was a rumor that Borderlands 4 will be shown at Summer Game Fest 2024.
