I've been meaning to post this for a bit now. I picked up the Moon Base Klaisus set with a gift certificate my brother gave me for Christmas, and it's pretty groovy, even tho it has some flaws for my specific needs.
Speaking of the layout, I really like that the street grid is set up at an angle to the sides. It makes for more interesting games when the Terrain is at angles to the Deployment Zones, and it's easier to avoid stuff just getting blown away as the streets provide open fields of fire in the directions that everyone needs to go.
I had thought we were going to have to rule that the Stanchions on the Sector Mechanicus stuff blocked LoS, but it turns out that when it's at odd angles and all mixed together like this, it actually blocks LoS pretty well. My Sector Mechanicus stuff, as you can see, is in a variety of different stages of completion. Most notably, I don't have any of the railings done, so we just played that all the walkways provided cover to anyone standing on them. The walls that came with the Moon Base mix really well with the rest of it, and even line up perfectly with the pipelines. My opponent was amazed that a bunch of it was just clipped together. It was solid enough while his Drukhari were swarming across it that he'd assumed it was all glued.
The one real negative to the set is that you have to be super careful when re-folding it. It's really easy to get a finger inside of the fold, which causes the cardboard to start tearing and delaminating.
Fluff-wise, my idea with this layout was that there had originally been some sort of nondescript installation here. Hab blocks, Admin buildings, stuff like that. Then someone attacked and blew it all up. That's the ruined walls that came with the Moon Base set. Then, quite some time later, the Adeptus Mechanicus found promethium deposits or something like that, and set up a facility to extract and process it. Recently, all contact with that facility was lost, resulting in the Jade Serpents Space Marine Chapter being sent to investigate, and clashing inconclusively with a Drukhari raiding force.
*The dimensions of the board are kind of odd. As near as I can tell, they're based on being folded down into A4-size stacks, minus a bit so you can get a finger in between the boards and the edge of the box and actually pull them out rather than having to dump them out.
