First, the link to the pdf. Zone Mortalis Rules pdf New from Forge World. I love, love, love the idea of small skirmish games in a ship. Boarding actions are my favorite Sci-fi settings and it is the reason that I chose to play Space Sharks in Warhammer 40k.
The owner of my FLGS created these spaceship tiles and they look beautiful. Also, they are very cheap for the level of detail that you are getting. I was planning on picking up 2 sets to replace my Space Hulk cardboard tiles, but now they are a definite purchase with these new rules. It also helps that he is a great guy with a great product. I will buy some to paint up for my next hobby purchase.
