Today marks the release of the final expansion for Atomic Heart, "Blood on Crystal." As it turns out, a famous Russian streamer worked on the DLC.
During one of his streams, Bratishkin (bratishkinoff) confirmed that he participated in voicing a character in the upcoming DLC.
Bratishkin explained that he signed an NDA (non-disclosure agreement) and until recently he was not allowed to confirm his participation in the voice acting work for Atomic Heart.
However, the streamer has not yet been allowed to reveal this character - the intrigue remains.
