Last week we kicked off a DIY cardboard costume contest with our friends from @NVIDIATegra to celebrate the launch of the new 3D sci-fi shooter, Shadowgun. While a handful of you wowed us with your submissions, there could only be one winner. And that man is Melvin Javier.

Melvin scored the victory with an incredibly detailed chest plate and hugeass gun. For the win, he’s picked up a brand new ASUS Slider, powered by the NVIDIA Tegra 2. Along with the tablet, we’re sending a Jawbone Jambox and an Amex gift card to get started in the Tegra Zone.

Honorable Mentions

As with all of our submission contests, we’ve rounded up the honorable mentions, but one stands a bit more honorably than the others. Because he had a video. Seriously, it made it such a tough call. In the end, the editor vote came down to costume detail and thus an Honorable Mention was born: Jonathan Gurrula.

We also liked the Jetpack inspired costume from Joseph Munoz:

and especially liked Bishop the RoboDog:

We wanted to give a big thanks to everyone that entered. This has been one of our favorite contests in quite some time. We’ve also notified all of the tweet for a t-shirt winners via DM, so check your Twitter inboxes! If you’d like a closer look at the winner and all the honorable mentions, we’ve included a full gallery below.
