Double Fine  had a highly successful crowdfunding campaign for Psyconauts 2 through Fig in 2015, raising more than $3.3 million–a third of that in the first 24 hours–for the much-anticipated sequel. Now, publisher Starbreeze Studios has invested another $8 million.

Fig crowdfunding is different than Kickstarter or Indiegogo, as people can pledge money as backers or investors. Of the $3.8 million raised, more than $1.8 million came from investors. Then in October of last year, Fig received SEC qualification, allowing it to seek investment for the game from "non-accredited" investors–people seeking revenue instead of the game and perks. Starbreeze's stake and any proceeds will come after other investors get their money from the game, which is why the company will be getting 85% of revenues until the investment is repaid, and then 60% thereafter.

"We’re really excited to be working with a publisher that has such a strong background in development, it makes them a perfect partner in our eyes," Double Fine said in a blog post, updating backers on the game's development. "We’re confident this will be a great marriage, and that our game babies will be the most handsomest of all time."

Double Fine is also using its own money to develop the game and will retain the IP rights.

“Many of us gamers who’ve grown up during 70’s and 80’s have at some point come across the great games from Double Fine and Tim Schafer. Games like Grim Fandango, Day of the Tentacle, Full Throttle, and Brutal Legend are all in the list of personal all time favorites for many of us. We’re very proud to be able to add this prominent collaboration to our Publishing business. Starbreeze is looking forward to support Double Fine in bringing the new and exciting game Psychonauts 2 to young and old gamers world wide” Starbreeze CEO Bo Andersson-Klint said in a press release.

Psychonauts 2 development isn't quite in full swing yet, and is scheduled to launch some time in 2018. However, it should not be confused with another project that Double Fine is working on for PlayStation VR, Psychonauts in the Rhombus of Ruin. That will be out on February 21.
