There’s a new version of Zap! on RPGNow. A lot of work went into this one. There are some rules clarifications, and significant new optional rules for things like speeding ship-to-ship combat, adding hit locations to regular combat, and pages and pages of new example equipment. Many of the most useful tables have been added to a new Appendix for easy printing, and there’s a whole bunch of new art, mostly from public domain SF comics of yore. Plus I’ve included a 5 page Quickstart PDF with just enough rules to generate a character and go.
Also, I’ve been running a lot of G+ Hangout games using Zap! If you want to join in the fun, follow me or the SFX! RPGs community on G+. We’re trying to set up an every-Tuesday-night SF RPG hangout, where I’ll be one of the rotating GMs, and I have pick-up games several other nights of the week. If I can get interest, I’d love to run a longer term campaign instead of pick-up one-shots. Drop on by!
