From publisher blurb:
Get the most out of your games with Thunderegg Productions' OSR Sci Fi GM Screen. Designed with the White Star Roleplaying Game's rules in mind, it's also compatible or easily portable to other SF OSR RPGs, including Stars Without Number, Hulks & Horrors and more.
In addition to being a GM screen, we've included a printer-friendly version so you can have one-page combat references and player handouts.
The player side features a beautiful cover page, a summary of both melee and starship combat rules, an example sector map with an FTL travel system and descriptions of each world.
The GM side includes the same sector map, planetary descriptions that also come with GM secrets, a combat summary, a random mission and reward generator and a convenient one-roll enemy generator that scales from mooks to bosses.
