Despite a lot of leaks around future updates for Genshin Impact, the game developers are ready to accept new testers. miHoYo studio officially invites all interested players to take part in the beta test of patch 2.6. You can send an application for participation until January 20 through an open form.
The developers warn all users that participation in the closed test requires the signing of an NDA. Testing of update 2.6 is likely to be a big event, but it is forbidden to talk about it before the official announcements.
In mid-February, Genshin Impact is expected to release patch 2.5, at the same time testing the 2.6 branch will begin. The main innovation of the update will be the release of two new heroes Heizo and Ayato, which should be announced very soon.
