Adding this to the comments for the public to see:
This is an amazing Mothership supplement! I have found these rules invaluable for creating derelicts and handling salvage for the PCs! Turning derelicts into "space dungeons" and translating dungeon-crawling rules and procedures is genius! I love this supplement so much! It has its own unique setting and lore, but the systems are perfectly serviceable in other campaign frameworks. And it includes a great monster creation system??? This whole product is an incredibly useful package for a Warden. Can't say enough good things about it! The "I search the Corridor" DLC expansion really rounds this out to give you a complete package. There are other derelict and salvage supplements out there that I enjoy, but to me, this is THE salvage supplement. If you only buy one of those, THIS would be my strongest recommendation! Love this!
