RAAAAAWWWWWHIIIIIIIIIIIIDEEE!!!!
Yup, it's time I feel to arrange all the knowledge into a single thread for ease of reading, and thus digestion!
Interesting Fact 1: There IS a Mechanicum presence in this book. Ordo Reductor. It is largely ancillary however, consider it's current stage as an Allies list. Pretty fun troops. Djinn Sight - No sneaky sneaky within 24" at all (Infiltrators, sod off!) regardless of LoS. And Eldar Pathfinders may want to stay at home. How does -2 to enemy cover save grab you? T5 and 3 wounds with a 4+ save. Pretty resilient. Also, they're Jet Pack infantry (no I'm not making this up!). Standard Weapon is the Lightning Gun. 18", S7, AP5, Heavy 1, Shred, Rending. Pretty filthy! Various upgrades available, but I don't want to spoil all the surprises. If this is standard type stuff, Mechanicum armies are going to be small, but tough as old boots.
Legion Army list.
Blimey o'reilly crikey Mavis. I don't know where to start. Oh, okay. Deimos Predator (well, any heresy era Predator really) has a 4 shot Autocannon. Slightly shorter range at 36", but a welcome boost, and the default weapon.
Volkite weapons are quite the surprise. Kind of ish Imperial Tesla, but with an extra automatic hit for every unsaved wound. Pretty respectable stats, but noticably shorter ranged than most small arms. Additional hits don't generate other hits. That would be silly. But it will leave Orks and Dark Eldar hurting a lot (mmmm...AP5!)
Phosphex bombs are one shot weapons o'filth. Wherever it hits, leave the blast template there petal. It's just been set light to. Dangerous terrain for anything open topped, or with a toughness value. Oh, and once the templates final landing place has been worked out? Owning player can move it 2" in any direction, as long as it hits more models. Very, very sexy! Oh and they're AP2....and Poisoned 3+.
Jetbikes....yeah Jetbikes rock big monkey nads. Seriously. Heavy Bolter as standard, and 1 in 3 can have a Plasma Cannon, Multimelta or Volkite Culverin (45", S6, AP5, Heavy 4, and that rule I was explaining earlier...)
Now I know what you think, but I am not yanking your chain!
Over to those other lucky sods with a copy of the book, don't want to hog all the glory!
