I saw this pop on on a random search on a popular auction site. I was intrigued- I'm a sucker for BigD. When I found this was a miniature and could be used in other games, I was sold. I searched YT videos for this and came here to purchase. I had to get two. SIS/TR fits so well in my current jam of OSR games like Mörk Börg, Forbidden Psalm and The Last War. There's a defense mechanic on SIS/TR that I will be a one-surprise thing, and then your players will have to use Player vs Character knowledge. I can't wait to come up with my own turrets. This came with the System Neutral rules and also the Mothership-applicable ruleset. This was helpful. The neutral rules list the available actions, but you decide how many it can take. in MS, it's two. Is there a universal conversion for HP? Inner box sides show SIS/TR faces.

I'm running this on the very last day of this month. My players want to fight a "god-like cube". I'm excited to torture them for their choices. I added a house rule to it, since I am new to GMing, when the players hear 8-bit music playing, they roll for sanity.
