40K: Upclose With Screamer-Killer Rules

The Screamer-Killer was teased by GW and now a clean version of it’s rules have been spotted!

Tyranid Players, I hope you’re as excited as I am! The Screamer-Killer is back and it’s looking MEAN and ready launch Bio-Plasma at a deadly new range:

This picture is apparently take of the rules from White Dwarf

For comparison sake, here’s the old (current?) Carnifex rules from the index:

So let’s break this one down.

  • It’s got the same statline/powerlevel as the previous Carnifex rules.
  • New Bio-Plasmic Scream 18″ vs 12″ range, Assault D6 vs D3, Same Strength, and -4 AP vs -3, 1 damage.
  • Monstrous Scything talons – same
  • May take Toxin Sacs/Adrenal Glands
  • May have Spore Systs
  • Spore Cysts opponents are -1 to hit with their ranged attacks that target a Screamer-Killer with Spore Cysts. This in not cumulative with Shrouding Spores (Venomthrope ability).
  • Still has Instictive Behaviour
  • Living Battering Ram – Still causes a Mortal Wound on a 4+ on the charge. In addition, it also adds +1 to hit rolls in the Fight Phase for a Screamer Killer that charged that turn.
  • Monstrous Brood is the same
  • Terrifying – Add 1 to any morale tests for enemies within 8″ of one or more Screamer-Killers.

Wow! -1 to be shot and +1 on the charge!? AND it can spew it’s Bio-Plasma 18″ and it’s deadlier!? Sure, it’s only BS 4 so if you’re advancing and shooting you’re only hitting on 5’s. Still, it’s nice to at least have the option and it’s D6 shots. But really you just want to get this Carnifex in there and rip it’s target to shreds.

On the charge this thing is getting 5 attacks that hit on 3+ and at S6, -3 AP and each does 3 damage. I’ll take it! I just hope the Tyranids will have a better way to get these guys across the board besides running…but even if they do, that -1 to hit really will add up.

Things are looking up for the Carnifex – now I’m curious about the OTHER options…


Who’s ready to say hello to our new Alien Overlords? The 4 Armed Emperor is coming…

  • Jabberwokk
  • BaronVonYoloing

    Just in time for an update on he community site. Synapse and Shadow in the Warp get buffs! Instinctive Behaviour feels less restrictive too!


    This book seems too good to be true for now.

    • Jabberwokk

      From what I’ve seen they brought back a lot of the things from 4th which was the best version of ‘nids and combined it with some of the best tidbits from 5th.

      The Tyranid hive which for years has been making miracles out of milquetoast are overjoyed. It’s like coming out of a drought.

      • BaronVonYoloing

        This is kind of my problem. Having also sat with Nids from their 4th ed book on I admit I’m a little apprehensive about any new codex update. Thankfully it looks like Cruddace has been taken away from this book lol.

        • Jabberwokk

          Thank God. He was pure pesticide to Tyranids. He wrote a heck of a Guard book though. I think he simply doesn’t have the imagination for non imperial armies although I’m sure there was more to it behind the scenes.

          I think all Nid players are (rightfully) cautious when it comes to messing with their stuff.

          • Bootneck

            I think one of the problems of many codex’s and Tyranids suffered heavily in the past is that the codex’s were never written for the current edition, they always come out late then the edition changed and the rules then suffered.

            All the changes to 8th have made Nids much stronger and these so far look excellent updates.

            I’m glad for all the Nid players tbh, quite sucky when your not on an even playing field.

          • Jabberwokk

            Hasn’t been an a long time. Though arguable 5th was at it’s strongest going into 6th. Tervigons pretty much were all you needed spawning Obsec gaunts and Smash. But yeah most of the book was hot garbage. But it did force evolution such as the “lictor shame” list.

          • Bootneck

            Never had a problem killed Tevigons really, instant death from force weapons always worked wonders in 7th for large gribblies and with lack of invul they were fair prey to most weapons.

            Plus there output was low, with there 3 attacks hitting at ws3 str5 or the smash attack. Nothing to write home about and easy to tarpit.

          • Jabberwokk

            Yeah but going into 6th you could smash for half the attacks for twice the str. Nemesis force weapons were an ‘issue’ (see: GG) for us. I skipped 7th because i didn’t want to reinvest in a half dozen flyrants only to achieve mediocre results.

  • Dan Osmond

    Looking at the change to synapse, seems like I won’t have to keep bringing a tyranid warrior brood to babysit the exocrine, biovores and hive guard then. Excellent.

  • Heinz Fiction

    The tail biomorphs seem to be gone. Didn’t they say something like “we’re bringing all those options back that are provided with the kit?”

    • Red_Five_Standing_By

      The Carnifex has 3 different unit profiles now. The Screamer killer probably has a basic tail.

    • Wampasaurus

      The Screamer Killer did not come with a Tail Biomorph. It was armed with 2 pairs of Scything Talons, Bio Plasma, and Adrenal Glands if you go by the 4th Edition codex

  • TCM

    I’m so happy about this, screamer killer is my favorite model. Assuming the points cost stays the same, I think they’ll be pretty viable now. I’ll finally be able to use one again 😊

  • Marcus Clark

    Geeze this thing will hurt, What I notice most is not only all these amazing combo attacks and buff; its that this thing doesn’t degrade!!
    That a real headache for any other player, as you need to kill it else even on 1 wound its still deadly.

  • MechBattler


    These are made to murder MEQs and TEQs. They can eat vehicles for breakfast too.

    This is what happens when you make a codex crappy for too long. Now those Carnis are all juiced up on rageroids and ready to grind everything into hamburger. I do not want to be on the wrong end of those. Though it makes me wonder how much more of a cuisinart the Haruspex is going to be.

  • Sniddy

    S6 won’t be great for dealing with vehicles – which is fine – any more and it’d be too pokey

    Should dice up MEQs and TEQs but I wonder….5 termies….lets say 3 hit, 2 wound, and none save. I suppose one could take 5 termies over 2/3 turns and not die in most situations
