To celebrate the 10th anniversary of the Battlefield franchise, Electronic Arts has deployed a sale for the series on Origin, with each installment available at $10 apiece. That means Battlefield 2 through Battlefield 3 (standard edition), which sounds like it would only be two games, but is actually several, are all the same price.
The discount is only available today, so you better oscar mike to Origin if you're interested. Did we "oscar mike" that right? No?! We've learned nothing!
