The massive Mass Effect nerds at Cards Against Humanity have teamed up with developer BioWare to produce an expansion pack for the vulgar card game — a small card pack themed around the beloved video game franchise that’s all about boning aliens in space, Cards Against Humanity announced today.

The 14-card Mass Effect Pack is now on sale for $1, with free shipping available to U.S. customers. If you want a pack, you should buy it sooner rather than later — “once we are sold out on the site, we are done forever,” Trin Garritano, director of events, emotions and various promotions at Cards Against Humanity, told Polygon.

Illustrator Cara McGee did the artwork for the pack; you can see the cover above, and the inside of the placard below. “And yes: Shepard and Kaidan smooch when you close the booklet,” Garritano noted with glee.

This is the second branded pack that Cards Against Humanity has produced, and the first one for a video game. You may remember the company’s House of Cards pack from three years ago.

Cards Against Humanity worked directly with BioWare to write the cards for the Mass Effect pack. However, to the chagrin of the folks at CAH, the partnership did not mean they got to play Mass Effect: Andromeda early. They’ll have to wait until March 21, just like the rest of us.

Other than that, Garritano said the working relationship between the two companies went smoothly. The idea sprang from a meeting between CAH and BioWare at San Diego Comic-Con a couple of years ago; just for fun, they started writing cards “that night,” according to Garritano. Cards Against Humanity’s writing team began the process, then teamed up with three BioWare writers — Karin Weekes, Ben Gelinas and Sam Maggs, whom Garritano described as “wonderful, perfect humans” — to fine-tune the cards.

“We had to push through a few non-sex cards”

There are just 14 cards in the pack, although that’s not for lack of trying. The writers came up with more than 700 cards, but “all but 14 of them were bad,” according to Garritano. In CAH’s defense, the BioWare writers kept doing one thing that didn’t help the situation.

“Whenever we’d look at the list of cards their team preferred, it was only cards about fucking,” Garritano explained. “We had to push through a few non-sex cards just to widen the appeal of the deck. It was an incredible problem to have and I am still absolutely tickled by this.”

Asked if the card pack is more or less NSFW than the Mass Effect games, Garritano said, “I mean one of the white cards is ‘an armored Krogan war-clitoris’ so I guess that’s up for debate?”
