NVIDIA is giving away free copies of the upcoming survival horror FPS Metro: Last Light, with select performance-thru-extreme segment GeForce GTX graphics cards. These include the GeForce GTX 660, GTX 660 Ti, GTX 670, GTX 680, GTX 690, and GTX TITAN. The offer is valid on participating NVIDIA add-in card partners, and is valid only on qualifying graphics cards purchased on or after today (Apr 16, 2013). Partners will be including coupons either inside the product package, or with the retailer invoice, which can be redeemed on Steam to count as a pre-order. At some point as the game's May 14 launch date approaches, you should be able to pre-load the game, and begin playing once it's released.
