For those that already own Deus Ex:HR and its Missing Link DLC, $4.99 will net you a download for the Director's Cut. Fans that own only the base game will need to pay $9.99, while newcomers will pay $19.99.
Director's Cut will offer developer commentaries and a New Game+ mode that carries over upgrades from past playthroughs. Director's Cut will hack into Steam's database on October 22 in North America and October 25 in PAL territories. If you prefer to stick with consoles, October 22 will also see the launch of Director's Cut on the Xbox 360 and PS3 for $30 and on the Wii U for $50.
