Zone Mortalis is the newest Journal Tactica for the third edition of the Horus Heresy. The book is short, of course, clocking in at 48 pages, of which some 13 pages are full page or nearly full page illustrations. Naturally, the main focus of the book is the new rules for Zone Mortalis. These in turn are based heavily on using the (older) 12 inch square tiles. That said, this one is full to the brim with new rules unlike other editions of the journal tactica which have quite a lot of lore in. This one doesn't have lore. It has rules by the bucket load, new units, missions, and everything else you might expect.
Terrain features heavily. There are ceilings all around (so you don't get to fly around in interceptors or use barrage, of course), walls, doors, corridors and tight fighting spaces. Corridors have confined spaced and you risk dangerous terrain deaths. Doorways have widths and you can get through some of your bigger models with a bit of ducking that impeded your setups and charges. Battlesmithing and intelligence tests help open doors that are otherwise closed off.
Happily, teleport strikes are back in full here! There's a whole load of other strategems fit to use as well which we will have a look at in the future. Missions and detachments exist by the load and we'll also look at them distinctly.
Today, I wanted to pull out 2 new rules especially.
The first is Breacher Charges. If you have a boarding shield and you are a high command or sergeant character, then you can take them for 10 points. It hits at S=10 and yields d3+3 damage against fortifications.
The second is the advanced rule of Unknown Enemies. This heralds a return to Space Hulk no less! Instead of deploying your figures, you deploy "blips". These are 25 to 40mm bases that you simply mark with a number or rune of your choice that corresponds to an entire unit. You move these blips at the movement rate of the lowest member of your squad or unit that it represents (you obviously
need to keep track of which blips corresponds to which unit). When you are properly sighted by another unit, replace the base with a single model from that unit, and arrange the rest in coherency around that first model with no model closer to an enemy that caused them to be revealed! I actually love this rule and am looking forward to seeing how it plays out (but let me know if you've already experimented with this!).
