UPDATE: The contest has been extended until September 12 at 11:59 p.m. PDT.

Petroglyph is bringing NVIDIA 3D Vision support to Rise of Immortals when it officially launches this summer, and the developer is celebrating by giving away a couple awesome prize packages! Two lucky players will each receive a 23" 120Hz NVIDIA 3D ready monitor, an eVGA GTX 560 video card and a pair of NVIDIA 3D Vision glasses. Petroglyph's also throwing in a T-shirt and mousepad, which they'll sign on request.

So how do you enter to win the 3D prize packages? Just participate in the Rise of Immortals open beta. That's it! Sign up for an account and play the game at least once by September 2 and you'll be in the running for the prizes. Optionally, you can also join the Rise of Immortals Facebook and Twitter pages.

The contest is only open to U.S. residents, but Petroglyph will be giving away additional prizes to international players on Fridays on Facebook and in the game's social hub. For more details, watch the video below!
