As my PCs approach the end of Iron Gods I have been adding content to foreshadow their post adventure path continuation. I plan to have them travel into space to combat the Dominion, Kytons, and possibly the Great Old ones. I really want to add ship-to-ship combat to the adventure.

I did however find a Kickstarter that seems very promising. If you are like me and want to send PCs into space it might be something you want to look at. Rather than link to the Kickstarter itself here is the link to the discussion about it on the Paizo messageboards:
