Deus Ex: Human Revolution Director's Cut popped into existence today, offering enhanced visuals, improved boss battles, and it comes bundled with the DLC. If, for some inexplicable reason, you already own the original but want a second slightly improved version, you can get it at a discounted price. Not being a fan of Human Revolution, I can't fathom why you'd do that, but it's nice to see Square Enix thinking about previous purchasers.
The Director's Cut comes with a bunch of upgrades, most notable among them are the boss battles. One of the most problematic elements of the previous version, they stripped players of all the options they had come to expect from the rest of the game, pitting them against dull foes in a dull fight that made me, at least, a dull boy. Now you can approach these battles with a bit more thought, enjoying variety that they initially sorely lacked.
The sickly golden filter that clung to every scene has also been toned down, likely because Eidos Montreal realised that it was clear enough that gold and wealth were important themes without having the colour forced into our eye sockets until we wept.
Both the Missing Link DLC and a "making of" video have also been bundled with the Director's Cut, the former of which is apparently rather good. The Tong's Mission DLC, originally a pre-order bonus, has also been thrown in for good measure.
Prices range from £12.99/$19.99 to £6.99/$9.99 if you already own the original version. If you also already own the DLC, you can get it even cheaper, for £3.99/$5.99 - but you won't really be getting much that you don't already have.
