The PlayStation 4 exclusive game, The Order is on sale for $20 off of the original price and it only released last month. A 30% discount is a pretty fast discount for a newly released game.
The game itself won some mixed reviews when it released, the game was generally accepted as a game with "all style and no substance." The Order: 1886 was visually pleasing, but lacked in features that would retain players.
Despite reviews, The Order: 1886 jumped to the top of sales charts, so, there's got to be something in that. If you want to pick it up and try it out for $40, all you need to do is head over to Amazon. While you're there, you might want to check out the PS4 and Bloodborne bundle, especially because it comes with The Last of Us for free.
