This weekend, you’re invited to join us in digging into the greatest mystery in videogame history: are there really millions of E.T. the Extra-Terrestrial Atari cartridges buried in the New Mexico desert?

While the dig (and resulting Xbox Entertainment Studios documentary) is the focal point of the weekend, it’s also a fine time to celebrate the last 30 years of gaming. To that end, we’d like for you to join us this coming Friday in Alamogordo, New Mexico for a retro fan meetup. The details:

What’s going on: Prep for  the big dig by playing classic Atari games, courtesy of Gamers Anonymous. Enjoy complementary food and soft drinks, and we’ll be raffling off prizes, including Xbox One games and an Xbox One system.

Where: Gamestop 516 1st St, Alamogordo, NM 88310 (map)

When: Friday, April 25 from 7:00pm – 9:00pm

Please note, the event is free and open to the public.

Then on Saturday morning, the main event gets underway. Make sure you’re there by 8:30am for check in as we kick off the dig with director Zak Penn at 930am.

We’ll also be giving away t-shirts to the first 250 people and canteens to the first 75 people at the dig site, so you’ll definitely want to set an alarm for that.
