Ages ago Ted Arlauskas did a Star Wars hack of Hero Kids, which inspired me to start work on a sci-fi expansion for the game. I'm not finished yet, but here's a quick look at the work that's gotten us from the original Hero Kids hero cards to sci-fi versions of the cards.
I'm sure you can all work out the various changes yourselves, but from here I need to create all ten of the sci-fi heroes, a bunch of monsters, and an adventure! Easy! :-)
The new sci-fi heroes (and monsters) are by Eric Quigley, as usual, and the custom border is by David Graffam.
