Tyranids Codex

Tons more rules rumors are out there, and we’ve cataloged as many as we can find. Checkout the latest rumors for the Tyranids Codex for units and more.

The following rumored rules teasers for Codex: Tyranids were spotted over on The Tyranid Hive, and there is a ton of new Warlord and Hive Fleet Traits that were teased. This is just a rumor, so make sure you add plenty of salt.

Here’s a few more tasty morsels that are supposedly from the new Tyranids Codex (edited for grammar and completeness):

I dont have the numbers but there are many reductions in costs for big bug melee and ranged weapons. eg. massive scything are now 10pts. massive scything talons in a pair are cheaper too (cant remember exact number). monstrous scything talons are much cheaper too. carnifex comes stock with tresher scythe which is now zero points and is the same wording as the hive tyrant. which is, it makes its profile attacks, which in the codex is 4, and then also makes the tail attack, which is now 1d3 attacks


  • Hive Fleet Attribute: Re-roll failed charges.
  • Warlord Trait: A To-Wound roll of 6+ during the Fight Phase deals 1 additional damage.
  • Stratagem: Brute Force (1CP)
    Use when a Benemoth unit successfully completes a charge. Roll a dice for each model in the unit that ended it’s charge move within 1” of an enemy model. For each roll of 6+, the enemy unit suffers 1 Mortal Wound. If the charging unit was a Monster, it instead inflicts a Mortal Wound on a roll of 2+.


  • Hive Fleet Attribute: Re-roll 1’s To-Hit during the Fight Phase.
  • Warlord Trait: At the end of the Fight Phase roll a dice for each unit within 1”/3”* of the Warlord. On a 4+ that unit suffers a Mortal Wound.
  • Stratagem: Hypertoxicity (1CP)
    Use during the Fight Phase. Choose a Gorgon unit equipped with Toxin Sacs. The biomorph does 1 additional damage on To-Wound rolls of 5+ instead of 6+.


  • Hive Fleet Attribute: Re-roll all failed To-Hit rolls during the Fight Phase for units who outnumber their opponents.
  • Warlord Trait: At the beginning of your turn roll a dice for each Wound your Warlord has suffered previously in battle, on a 6+ it regains that Wound.
  • Stratagem: Endless Swarm (2cp)
    Select a destroyed unit of Termagants, Hormsgaunts, Gargoyles, or any Hydra Infantry unit that has been completely destroyed. Add an identical unit to your army and set it up as reinforcements wholly within 6” of any board edge, and more than 9 inch from any enemy units.

Not sure if this is actually the Hydra stratagem, if it simply has a bonus when used by Hydra armies. The wording implies the later, but I couldn’t find another trait that specifically mentions Hydra in the leaks.


  • Hive Fleet Attribute: A unit with this adaptation (other than units that can Fly) always has the benefit of cover for the purpose of shooting attacks. If the unit advances or charges, however, it loses the benefits of this adaptation until the start of your next movement phase.
  • Warlord Trait: Enemy units do not benefit from Cover against attacks made by the Warlord or friendly units within 3” of the Warlord.
  • Stratagem: The Enemy Below (1CP)  Use this Stratagem during deployment when setting up a Jormungandr Infantry unit. Instead of deploying normal set this unit up underground. When you set up a unit of tunnellers (Raveners, Trygon, Trygon Prime, or Mawloc) any number of units that have been set up underground may deploy with them. Place that unit within 3” of the tunneller and more than 9” away from any enemy units.


  • Hive Fleet Attribute: Units may charge after Falling Back.
  • Warlord Trait: Choose a unit within 6” of the Warlord, it may fight first in the Fight Phase even if it didn’t charge.
  • Stratagem: Opportunistic Advance (1CP)  Use in the Movement Phase. Choose a Kraken unit that does not have the Fly keyword. When Advancing you can double number you roll when determining how much to add to the unit’s Movemnt characteristic.


  • Hive Fleet Attribute: If a unit does not Move, it may re-roll 1’s To-Hit when shooting.
  • Warlord Trait: If an enemy Psyker within 18” of your Warlord fails a Psychic Test they suffer D3 Mortal Wounds.
  • Stratagem: Against Shadows (1CP)  Use when an enemy psyker attempts to cast a spell within 24” of a Kronos unit. That psyker can only use one dice for their psychic test.


  • Hive Fleet Attribute: Each unit may re-roll 1 failed To-Hit and To-Wound roll when it shoots or fights (needs exact wording before confirmation).
  • Warlord Trait: After deployment, but before the first game turn, you may re-deploy your Warlord.
  • Stratagem: War On All Fronts (1CP)
    Use during the Fight Phase. Select enemy unit within 1” of one Flying and one non-Flying Leviathan unit. You may re-roll all To-Hit and To-Wound rolls of 1 for attacks against the enemy unit made by friendly Leviathin units.

Behemoth tyranids hor wal


  • 30 inch norm crown that negates the effect of IB, but doesn’t give you anything else.
  • there is a relic for any character that gives either +1S, +1A or +1T during fight phase. roll dice to see which buff
  • a relic venom cannon. same stats as a venom cannon except d6 shots. but if the target is within 12″ it auto hits and always wounds on 2+

Tyranid Psychic Powers

Warp blast is the same except at a unit of 6 it deals d3+3 instead of d3

1. Dominion

4. Onslaught

5. Paroxysm

6. Psychic Scream

If that unit is psyker, roll 2D6, beat their ld, and they randomly forget 1 of their powers.

General Unit Rules & More:

  • swarmlord is NOT leviathan keyword. i caused some confusion from my wrongly reported warlord traits. swarmlord has the re-set up your warlord before the game starts one. the leviathan trait is in fact this:
    1 per battle round. you can reroll a single hit/wound/dmg /advance charge or saving throw for the wl
  • old eyeball 200 pts. 9w character add 1 roll to hit if charged
    extra attack now on 6 only
    doesn’t degrade

  • Mawloc: same ish new weapon, bio rattle Strength user, ap1 1 damage, toxinspike, strength 1 d3 damage , always wound on 2 but not on vehicles
  • Stinger salvos are now 24 inches, so that is factored into every existing model that can have them. eg. slight cost increase for everything that has them
  • Crone Lost 1 attack. Tentaclids are now 4 shot.
  • A lot of weapons cost are slightly cheaper and inbuilt into the base cost of units that only can have them.
  • tyrant guard, scything talons are still 0. rending claws are still 2. boneswords are still 4. crushing claws are 12 (yay i guess)

  • hive tyrant is now t7, 12W. wings will have deepstrike. has a base 4++. down one attack [to 4]. didnt manage to see the pointage or the wargear options. no idea if monstrous rending claws are still a thing. hive tyrants can still take MRC
  • Swarmlord does still have hive commander, and is t7, 12w, 4++. his blade parry makes it 3++. no other notable change
  • old one eye is is now 9 wounds. 200 pts. hits of 6 generate one additional attack. can be equipped with a scything talons relic that +1s ap-3, 3dmg, +1 attack. uses behemoth warlord trait

  • maleceptors deal 3 mortal wounds if we roll a 6 on that weird aoe ability. it knows 2 spells and can cast and deny 2 spells. also t7. also 4++
    maleceptors total pointage including wargear is 172. T7, 12W
  • venomthropes and zoans are still fielded as units of 3 venomthropes when in grp of 3 also affect monsters. when in a grp of 6, the aura becomes 6″.

  • Carnifex Biomorphs:
    -1 to hit from enemy shooting biomorph is 10 pts
    +1 attack on the charge is 8 pts

If these rumors are true, all the new tidbits look interesting for sure.The Tyranids are really looking like a force to be reckoned with, and an army that just won’t go away.  But, once again, these are just rumors, we don’t know anything for sure yet until GW’s previews start.

Make sure you’re checking back in for more rules teasers, we’ll be putting them out as soon as we get them,
