Yeah, send me an email (it's on the copyright page of the game) and I can take care of it for you.

Thanks! I went ahead and added an extra community copy to the batch to count your physical purchase :)

There are new community copies up now. If you don't manage to snag one, shoot me an email (oneseven@gmail) and I can get one to you.

Hi Carmilla! There are new community copies available now.

Yep, it's Creative Commons (CC-BY).

Yeah, I'd do 1d6+level, but they have to make a roll to attempt it. On a 6-, something bad happens (maybe they do some damage to the character instead of healing them or maybe they lose their healing powers for a day).

You can say:
"This game is based on Caltrop Core, published by Titanomachy RPG, and Lasers & Feelings by John Harper, both licensed for use under a Creative Commons Attribution 4.0 license: http://"

If you're level 2 and have 4 hit dice, you'd roll 4 dice and keep the best 2 to determine your HP.

Cool! Thank you. :)

Awesome! Thank you so much.

Yep, there are several fan versions. The game is released under Creative Commons BY-SA license so people can use it to make their own stuff.

You can take abilities from other classes (or invent new ones).

Thank you!

The group can make the call together. Usually, "expert" means that your character's Style or Role applies to the situation.

Glad you're enjoying it.

Shoot me an email (oneseven at gmail)

Unfortunately, I don't currently have a way to do that. I'll talk to OMM and see if there's a way to integrate it, but I can't make any promises.

Yeah. Send me an email and I'll get you one. oneseven at gmail.

There are some community copies available now! Let me know if you don't get one and I can send you a code.

Yeah, the question "what does the signal want?" is tricky, but that's part of the fun of being the OPS player, imo. It might have a coherent agenda, working across SRMs and agents, or it might be an inscrutable alien force, with no sensible motives or goals.

By default, I'd say the signal always wants to: break free, propagate further, and infect as many systems and minds as possible.

Yes, that's fine.

It was made as a companion to Dungeon World, but you don't need DW to play it.

Yeah, putting it on itch could work. Ping me on Twitter and I can help draw some attention to it when it's ready.

Probably the Dungeon World reddit would be interested in it, too.

When you fight, use the rules for doing something risky (2d6+stat). On a 10+, you deal damage. On a 7-9, you trade hits with your foe. On a 6-, you get hit.

(That's one way to interpret the roll. It's not totally set in stone and is flexible by design. Let the situation guide your judgment calls.)

Your armor value subtracts from damage you take.

Yes, I add them regularly, but they disappear fast. I'll do another batch tomorrow (they usually get added on Monday).

Site is back up.

Yeah, it's down right now. The site admin is working on it.

Glad you're enjoying the game.
The PCs get profit every time the crew fills their XP track and earns an advance.

Looks good!

I'm not aware of any.

Yeah, that's ok.

Yep, that's fine!

I add them in batches regularly, usually at the start of the week. They go fast, though.

Glad you like it!

The fonts are Souvenir and Univers LT.
(You can find out what fonts a PDF uses by opening it in Acrobat and going to File > Properties > Fonts tab.)

I updated the license to allow for commercial games. See this devlog post here:

Yes, that's ok!

Yep! It doesn't say it in the text, but it's licensed the same way as Dungeon World: Creative Commons, attribution.

That looks good! Thank you.

Yes, please do!

That was just a bit of fun. It was made in 2012.
