I knew there was a reason I have an Imperial Navy boarding party (which seem to be my most popular posts, just ahead of the triage stuff).
Well, just to give me a kick up the arse and more projects to work on, Forge World are releasing a mini-game / expansion game called Zone Mortalis, aimed at creating close quarters combat in narrow corridors (essentially Space Hulk Plus...)
The rules, when they are properly released, seem like they will focus on the four 1'x1' modular tiles that can be purchased separately for £25 each or £90 pounds for the set. Of course there's no need to actually use these, old Space Hulk boards, Necromunda bulkheads or whatever you have to hand will surely suffice. There is a section on "terrain" and boards within the rules.
Here are the currently experimental rules for Zone Mortalis. Give them a whirl and let me know your thoughts.
Here is a sneak peak of the game and the rather pricey terrain in video form - it does look good but I think the cereal boxes and pringles tubes will start amassing in my house soon...
Here's coverage from From The Warp on the rules
And from Apocalypse 40k here
I would have written more of my own coverage, and will do later, but this is my "excited kid at Christmas" blurt of a post
