Nvidia has updated the collection of games bundled with purchases of new GeForce 900 series graphics cards, giving gamers Batman: Arkham Knight in addition to The Witcher 3: Wild Hunt for free with qualifying purchases.

This new game bundle is pretty similar to the old bundle, which gave eligible graphics card buyers a free copy of The Witcher 3. You'll still get a copy of The Witcher 3 with a purchase of a GeForce GTX 980, 970 or 960 desktop graphics card, or with the purchase of a gaming laptop containing either the GTX 980M or 970M.

Where the bundle changes is with the addition of Batman: Arkham Knight, which will be given away to those who purchase either of Nvidia's high-end GeForce GPUs: the GTX 980 or GTX 970. These are the only two cards that get Arkham Knight, leaving GTX 960, 980M and 970M buyers with just the one bundled game.

Buyers of the flagship GeForce Titan X, or the mid-range GTX 750 or GTX 750 Ti, will not receive any games with their purchase. Similarly, any mobile GPUs lower the GTX 970M (including the entire 800M series) are left without bundled games.

Both The Witcher 3 and Batman: Arkham Knight are set to be graphically intense titles that will push gaming machines to their limits, and both include a variety of Nvidia's GameWorks features to enhance the experience.

The game bundle is available everywhere except China, and codes are valid until July 31st. The Witcher 3 will be delivered via a DRM-free GOG download when it launches on May 19, while Arkham Knight will be distributed through Steam after its June 23 launch.
