Yesterday, we took a look at Riptide GP for Tegra devices with the addition of controller support. To celebrate the update and all the fun that adding a controller to your Tegra tablet can bring, we've once again teamed up with NVIDIA to bring our most massive giveaway yet: The Riptide Gaming Power Pack.

Just take a look of all that is in store for the winner:

• ASUS Eee Pad Transformer 32GB with keyboard dock.
• YOUR CHOICE of Tegra powered superphone - Motorola Atrix (AT&T), Motorola Droid X2 (Verizon), LG G2x (T-Mobile), or Motorola Photon 4G (Sprint)
• Logitech Wireless Gamepad F710
• $25 AMEX Giftcard for TegraZone games, including Riptide GP

Is this the best giveaway we've done yet, or what? Yeah, that's what I thought. Free phone, tablet, and accessories to go with it -- I'm actually jealous that I can't enter!

Before we get into the details, I want to take this time to give a huge shoutout to NVIDIA -- they've been extremely supportive of Android Police and everything we do. Without them, we wouldn't be able to offer as many giveaways as we have in the past (and will continue to do in the future), so we want to let those guys know how much we appreciate them and their support!

Alright -- let's go over the hardware specs of all the device up for grabs, shall we?

What You Get

ASUS Eee Pad Transformer + Keyboard Dock

The Transformer is one of the most unique Honeycomb tablets on the market due to its one-of-a-kind keyboard dock accessory. The keyboard dock ultimately transforms the... Transformer... into a fully functional Android-powered laptop. That's not all, either -- the dock includes its own battery, which essentially doubles the battery life of the tablet. Win + Win = Win... ing... er?

• 10.1-inch 1280x800 LCD display
• 1GHz dual-core NVIDIA Tegra 2 processor
• 1GB RAM
• 32GB built-in storage
• 5MP rear shooter, 1.3MP front camera
• Android 3.2 Honeycomb

Keyboard features:

• Internal battery that charges the tablet
• 2x full size USB ports

• Laptop-style touchpad

Aside from that, you'll also get to choose one of the following phones (there is one from each US carrier):

Motorola Atrix 4G (AT&T)

While the Atrix has been out for over six months, it's still a powerhouse of a device:

• 512MB RAM
• 8GB internal storage, microSD Card slot

The Photon is a lot like the Atrix (only bigger), with a sleek design and powerful specs:

• 1GHz dual-core NVIDIA Tegra 2 processor
• 1GB RAM
• 16GB internal storage, microSD card slot

Aside from a tablet and a phone, you'll also get the sweet Logitech Wireless Gamepad f710 that we reviewed earlier:
