War Thunder by Gaijin Entertainment is a large-scale military simulation with an emphasis on realism, and the game's known for one thing in particular: a community that just cannot stop itself from leaking classified military documents to win forum arguments about virtual tanks. Well, that and having game footage used (without the studio's knowledge) in the background of Russian propaganda clips.
Usually it's Gaijin Entertainment that's mopping up the mess, sternly reminding players not to leak stuff with potentially severe real-world consequences. But now Gaijin itself has made a colossal and unforced error linked to a real world tragedy.
