Teens in Space: Core Rulebook

Watermarked PDF

Impulsive Youths, Vast Cosmos...


Teens in Space Cover snip

Teens in Space is a space opera RPG that uses the “Powered by Kids on Bikes” system, first used in the award wininng Kids on Bikes. Written and created by celebrated game designers Jon Gilmour (Dead of WinterKids on Bikes) & Doug Levandowski (Gothic Doctor, Kids on Bikes) with the evocative art of Heather Vaughan (Beneath Nexus, Kids on Bikes), Teens in Space is a rules-light storytelling system that takes you into the cosmos for adventure and profit.

Kids on Bikes is NOT required to play Teens in Space.

The Adventures of Teens in Space take place across the vast and sometimes uncharted reaches of the universe, with fantastical things like: 

  • Diverse and interesting alien species of all shapes and sizes
  • Powerful faster than light space ships that can take you across the universe
  • Strange, beautiful, and even terrifying worlds ripped right from your imagination 

Teens in Space takes characters to places beyond our celestial comfort zone, out into the cosmos where anything and everything *could* happen. 

Group of Alien Characters

Teens in Space is a 126 page, rules-light, fast-paced storytelling game using the "Powered by Kids on Bikes" system meaning that many players will feel right at home. Despite the added layers of Sci-Fi this remains a game in which you can jump right into the action and start playing RIGHT NOW!

Using familiar stats like GRIT, CHARM, FIGHT, FLIGHT, BRAINS and BRAWN, you’ll jump into the action. Each skill is represented by a polyhedral die based on your character’s competence. More sides = better chance of success.

That being said, even low stats always have a chance of success, as any max result EXPLODES leading to an additional re-roll contributing to the results. Lower sided dice mean bigger chances of explosions!

Character and Ship Creation

Character creation is a hallmark feature of the "Powered by Kids On Bikes" system, and we've added even more of what you loved from before with Teens in Space!

Featuring an all new, immersive ship-creation process, you and the other players will create their collective "home away from home" (and in part the very universe) for your game as you create your characters. You’ll start with Tropes you know and love (like the Newbie, the Merc, or the Captain), you’ll flesh your characters out by developing their relationships to the crew and the ship!

Did we forget to mention ship improvements?  

Teens in Space also features a vast series of options for the customization of your ships as your trek across the cosmos. From specialized upgrades effective in the new ship to ship combat system, or more utilitarian instrunments that can help you solve the mysteries of the universe - go in for the long haul and build that personal connection with your vessel! 

Possibly the greatest tool in your high tech arsenal, the ship will no doubt be getting you out of a pinch or two. You'll need to choose how you upgrade your ship wisely!

The vast cosmos are waiting to be explored… does your crew have the moxy to claim glory?

The "Skilled At..." Improvement mentions Ace Pilot in the example of non-overlap. Is this a reference to what became Hot Shot Pilot?

Both this - and your prior comment are both copyedit errors. We'll be updating the PDF, and adding it to our Errata for the next print run.

There's at least one mention of "Epoch creation" (page 73 at the start of the Species appendix) but I haven't found anything by that name elsewhere in the book.

I’m seeing weird lines on the front and back cover. Not anything that effects gameplay, but annoying.

The difficulty table on page 27 is messed up. The explanations for 10 to 12 and for 7 to 9 are identical, and there's nothing given for ranges between 7 to 9 and 1 to 2.

Mine is messed up too. "19 to 17" should read "17 to 19". The explanation & example for 10 to 12 duplicates the ones for 7 to 9. There is no entry at all for 3 to 6 results.

For those w/out Kids on Bikes, here's the explanations & examples for the 3-6 and 10-12 results.

3-6 | A task where success is likely for all characters except those who aren’t skilled or who have a low stat in that field.
Examples: A lucky person drawing a non-face card from a deck; a character silently withstanding a verbal berating.

10-12 | A task where success is impressive — but completely expected for characters skilled at it.
Examples: A strong person prying open a heavy, locked door; a computer whiz repairing a computer quickly under pressure.

Hey everyone - thanks for letting us know! We have adjusted this and uploaded an updated file here on DTRPG correcting the issues on page 26. We have also added a downloadable Errata page for this on our website for anyone with the physical book.

Please let me know when the physical book is reprinted with the corrections. I will hold off buying it until then.

BTW, fire your proofreader.

Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
