"This may be a fake story for numerous reasons"
And I say no more reason to be fake than the bombing of four trains/buses on 7th July 2005?
"in the game Siegafal, an xbox add-on game for windows 10, Arabic has become the language of choice in the chat channel"
Perhaps the game is being adopted as a cover for a communications channel "below the radar"?

Well, you are among the 10% who cannot apparently follow that no one, not even sandrats, are dumb enough to talk in Arabic - in the clear - on an open channel which is monitored 24/7 about a plot to kill people in multiple locations.

They do not need games for that an iPhone works better and can be had anywhere.

I trust my BS detector. Sure i’m wrong sometimes, but it’s like bluff catching in poker. Use it sparingly and don’t become the table cop.
