I have added the playtest for BOOM! Zap! to the 3PoS Digital Library. I haven’t had a lot of volunteers to help playtest, so this might spur some interest.
Boom! Zap! is the spiritual cousin to The Rules with No Name, a western skirmish game that appeared in an old MWAN, long ago. It covers a wide range of pulp SF skirmishes, in different milieus.
I am still working on it, but feel free to download and send feedback.
