Yes, that headline really is what it looks like. Reddit user Ochotonida decided to take the multiplayer shooter that is Overwatch and use it to simply recreate Tetris from the ground up. It’s not some variant on Tetris in which you use, say, Tracer’s teleporting powers or something on Tetris blocks. It’s just straight-up normal Tetris, except now you can play it in Overwatch.
The impressive part, naturally, is the amount of work necessary to turn the shooter into a game of Tetris, since it is not hard to find a version of Tetris you can play in other fashions. With these sorts of modifications the real test is always about the challenge of making the thing in the first place, not why you’d want to turn Overwatch into Tetris. But hey, maybe you see playing nothing but Tetris in the game as some sort of moral protest against Blizzard’s recent corporate actions. More power to you.
