The only way you could possibly improve Metal Gear Solid V: The Phantom Pain would be to let players dress Snake as James Bond. So dapper. That's why the fact that the Metal Gear Solid V: The Phantom Pain Costume & Tack pack being available for download is such good news.
For $4.99, you get seven different costumes, with three for Snake himself or male Diamond Dogs recruits: Naked Snake's Fatigues as well as the Sneaking Suit, and a tuxedo.
You get two costumes inspired by The Boss and Eva from Metal Gear Solid 3: Snake Eater, but you can't use them on Quiet. You can only outfit your female Diamond Dogs soldiers with them, but this makes sense in the context of the game (which I won't spoil here.)
Last but not least: Horse armor! The Western and Parade Tack armors are available to ensure your horse is looking as fly as possible, even when it's relieving itself on the battlefield.
The costumes are $0.99 apiece, so it's a bit of a money-saver if you go ahead and buy the whole pack if you're interested. And why wouldn't you be? Horse armor!
