I use 5150 for all my Sci-Fi battles. As a result, I've knocked some reaction tables and rules for using Judges in a game of 5150.
These rules are the second version and include tweaks to how the Ricochet bullets work. During play testing, the richochet was being used more often than the standard bullets. As a result of the tweaks, standard bullets are more lethal and rcihchet bullets play more like they do in the comic.
I've also updated how a 'Heatseeker' bullet works.
