It was a year ago, almost to the day, that Double Fine showed off some Psychonauts 2 "prototype gameplay" in a recreated version of the original game's summer camp. The elements on display "looked nice but weren’t designed to be part of the full game," the studio explained in a Fig update. "They were simple spaces that didn’t incorporate any of the tricky platforming and open exploration we want to be be central to Psychonauts 2." The new video released today, however, is much closer to what the final game will deliver. 

"The 'First Playable' is an area of the game that we’ve built to test our new pipelines and workflows across all departments—art, animation, tech, design, cinematics, etc," Double Fine wrote. "We’ve tested all of this a lot during pre-production, but this is our first big attempt to create a fully arted up, fully playable chunk of gameplay with all the systems, art, gameplay, and tech working in the same place." 

The segment is basically a "vertical slice," although the studio isn't using that term because it implies "a level of polish and completeness" that isn't currently there. But it's a fully playable area with "player movement, combat, quests, experience, UI all working together with scratch dialogue and audio, some rough visual effects, textures, lighting, even a cut-scene," which enables the studio to test and iterate on the systems—and show off what it's doing. 

There is, around the midpoint of the video, an unexpectedly up-close look at a goat butthole, and it's not entirely just a cheap joke: The Fig update also digs into "how a goat gets made," from simple sketches to more detailed drawings, a 3D model, texturing, and animation, which actually involved a real visit to a goat farm so the subtleties and nuances of goat movement could be properly captured.   

"It takes nine goats to the say the F-word," Double Fine boss Tim Schafer explained helpfully. "I've done a lot of goat porn. Graffiti. Goat porn graffiti." 

Double Fine is also "pretty close" to sharing details on backer rewards, which it expects will be shipped out in three batches: "One batch of stuff that doesn’t take too long to make (shirts for example), another batch of stuff for the more complex or custom things (like action figures) and a final batch for stuff that requires the game to be complete." Backer surveys should start arriving "really soon," it added. 

Psychonauts 2 is still far from a proper release date, but the last time we looked it had an "estimated delivery" window of summer 2018. More information about what's cooking is up at psychonauts.com. 

The Humble Store is giving away another old-time classic as part of its End of Summer Sale: Psychonauts, the Double Fine adventure-platformer about a kid with a cool hat who goes off to summer camp.   

I have mixed feelings about Psychonauts. I loved the writing, the voice acting, and the bizarre, beautiful game world that was filled with things to discover. But the platforming could be repetitive, and often outright infuriating. I never did finish it—I ran out of patience midway through the godawful Meat Circus, and decided I was close enough to the end to call it a day. 

I've never gone back, in part because I don't want to spoil the magic of the memories, but "free" is awfully tempting, and according to the Wiki the level has been made considerably easier in the Steam release. Which is what you'll get with this Humble freebie: Go here, add it to your cart, and after you check out you'll be emailed a Steam code.   

Since we're here, a few other Humble Store deals of note:

• Metro Redux bundle: $7.50
• Darkest Dungeon: $10
• The Talos Principle: $10
• Luftrausers: $2.50
• And one more, let's see... How about Shadow Warrior 2 Deluxe for $25 (the regular edition is on for $20, but the soundtrack alone is worth the extra fiver)

The Humble Store End of Summer Sale runs until 10 am PT on September 21, while Psychonauts will be free until the same time on September 16.

Following the recent announcement of a crowdfunding campaign for Psychonauts 2, Double Fine and 2 Player Productions put out a three-part documentary about the origins of the original game. It s a lovely, candid look at how Tim Schafer and co. scraped together their first platformer without much of a clue how to pull it off. I ve yet to watch part three which just came out, but based on the previous installments it will be a fascinating combination of old footage from the game's development, other stuff from Double Fine s early years, and some hokey Tim-Schaferisms.

Rarely does the public get quite this sort of inside look at game development, particularly these days. A particular note of interest: Psychonauts was actually cancelled after leadership roles shifted at Microsoft, and some of their feedback said that the game might be too funny for a wide audience. Luckily, Double Fine finally secured a deal with Majesco to publish.

Watch the Psychonauts Retrospective: The Color of the Sky in Your World, parts 2 and 3 below.

Psychonauts 2 was announced at The Game Awards today, albeit in a roundabout way. It's not officially guaranteed to happen yet, with a $3,300,000 crowdfunding campaign underway on Fig. But Fig will only provide one portion of the development funds. Double Fine will be providing a big portion of the funds themselves and an unnamed outside partner will be providing the remainder. 

The campaign page is live now, and is ticking up at a pretty quick rate. Rewards are doled out in tiers, similar to Kickstarter, and you can pick up the game, once/if it's completed, for $33 bucks. Donate enough to be an official investor, and you can pick up a piece of the profits.

Be sure to watch The PC Gamer Show next Tuesday, as we'll be talking to Tim Schafer himself. Join us as we try to take a peek into the industry veteran's mind about Double Fine's surprising endeavor. 

Watch the pitch video below.

Nothing says “indie” quite like breaking down the walls of copyright and adding a bunch of characters from games you had no hand in making. And wouldn’t you know it, Gaijin Games is doing just that with their cardiovascular improvement simulator, BIT.TRIP Presents: Runner2: Future Legend of Rhythm Alien or "Runner 2" for those who need to work on their lung capacity.

Those who drop $3 for the “Good Friends Character Pack” will have access to Psychonauts’ Raz, Cave Story’s Quote, Machinarium’s Josef, Super Meat Boy’s Dr. Fetus, Portal 2’s Atlas (who’s Steam exclusive), Bit.Trip’s invisible Commander Video, and Spelunky's, er, Spelunky Guy.

We’re a little bummed that the DLC doesn’t offer new levels of some kind, but it’s hard to complain about anything when it’s a paltry $3, which, as developer Dant Rambo notes, is less than "a bag of hot dog chips." Still, here’s hoping we get some new levels to break in this new cast somewhere in the near future. In the meantime, why don't you watch these character introductions narrated by none other than Charles Martinet, aka, the voice of Mario. Yes, that Mario.

Just as promised, Steam Trading Cards is now live. The virtual cards can be earned by playing participating games on Steam, trading with other users, or buying on the Steam Marketplace. Complete a set to create a badge, earn rewards and XP, and level up. The user with the highest Steam level at the end of the year gets to high five Gabe Newell while announcing Half-Life 3. In space.

In other true facts, I'm already hearing from users playing the Steam marketplace to profit off the cards' initial popularity. One user I spoke to has been buying low and selling high to pad his Steam wallet, even creating scarcity by buying up low-value cards in quantity. I'll keep an eye on marketplace prices as more users start trading the collectibles.

I was hoping to find a good deal on a 1952 Mickey Mantle card, but unfortunately, baseball isn't a participating game. You can see which of the games you own are participating here.

Brad Muir may be busy running Double Fine's latest Kickstarter, Massive Chalice, but he's still got time for his greatest vice: Dota 2. "I'm extremely addicted," he says. "I'm playing all of the Dota 2 I can handle!"

"It boots and loads games so quickly it's ridiculous. I feel like I'm in the future."
What's in your PC?

I used to be really into building my own PC's but this time I around I had a good friend help me out. I just haven't been keeping up with hardware trends. But the rig that he spec'd out for me is about a year old and it's still a beast! Core i5 3570k, 8GB DDR3 RAM, GTX 580, 256GB SSD. It was such a major upgrade to my old rig!

What's the most interesting part of your setup?

I think it's a pretty normal setup. My PC is at a desk in the guest bedroom with a desk chair. There isn't really anything fancy about it. But I will say that upgrading to a PC with an SSD has been revelatory! I know that it's not uncommon nowadays, but the speed just hasn't worn off on me. It boots and loads games so quickly it's ridiculous. I feel like I'm in the future.

What’s on your desk?

It's so messy it's embarrassing! I keep a lot of stuff by my PC. There are a ton of books, Magic cards, and official-looking pieces of mail laying around that I should be dealing with. But mostly I'm just ignoring these things and playing Dota.
"Games were a great escape for me and let me really feel in control of what was happening in the world."
What are you playing right now?

Oh man I'm playing all of the Dota 2 I can handle! My younger brother roped me into the game and I'm extremely addicted right now. I'm definitely looking forward to The International 3 in Seattle in August! I've also been playing some Crusader Kings 2, XCOM: Enemy Unknown, and X-COM: UFO Defense (old school!) for MASSIVE CHALICE research! It's pretty awesome when these games are considered "research" for your job!

Why do you game?

When I was a kid I think it was all about having a safe space. Games were a great escape for me and let me really feel in control of what was happening in the world. Nowadays I think it's a lot different—games are a great way to socialize and keep in touch with my brother. And I think they're a great, interesting way to apply stress your brain in a positive way. I'm so excited that games are offering all sorts of diverse experiences these days. I'm loving the indie community—it's just great that you can have games like Kerbal Space Program and Cart Life in the Steam store next to Call of Duty. Amazing!

Amnesia Fortnight is how Double Fine turns creative people into games—everyone on staff is hit on the head with a brick or some other amnesia-inducing device and spends two weeks prototyping new ideas. It's how Costume Quest and Stacking were greenlit, and last year Double Fine introduced us to the process by letting us vote on concepts in its first Humble Bundle collaboration. Those prototypes, and a few more, are now available again through the current Humble Double Fine Bundle.

Along with Psychonauts, Costume Quest, Stacking, and Brütal Legend, beating the average price (currently $8.15) will now also get you Windows-only concept games Autonomous, Black Lake, Hack n’ Slash, Spacebase DF-9, The White Birch, Happy Song, Brazen, and the Costume Quest prototype.

Also added are the prototypes' soundtracks, as well as 2 Player Productions' Amnesia Fortnight 2012 Documentary, which was originally released as daily video updates during the two-week prototyping crunch. Check out the trailer below:
