This is SprueSentry strategy commentary, not official rules. The parts of this detachment reprinted or amended in the Tyranids Faction Pack version 1.2, the release that arrived with the 26 August 2026 balance update, are confirmed against that document, re-checked on 27 August 2026. The rest of the stratagem and enhancement lists come from the 10th-edition codex and are cross-checked across two independent community rules mirrors. The Detachment Point cost and enhancement points come from the official Munitorum Field Manual version 1.3, updated 26 August 2026. Points move with every update, so confirm them in the Warhammer 40,000 app before a game.
At the start of each battle round you can select one Synaptic Imperative, active until the end of that round for every Tyranids unit within Synapse Range. Each can only be selected once per battle. Synaptic Augmentation grants a 5+ invulnerable save, Surging Vitality adds 1 to Advance and Charge rolls, and Goaded to Slaughter adds 1 to melee Hit rolls.
1CP. One Tyranids unit within Synapse Range gets a Synaptic Imperative of your choice, even one already used this battle, instead of the army's active one.
1CP. Until the end of the turn, friendly Tyranids units within 9" of a chosen Synapse unit count as within Synapse Range.
1CP. Pick a Synapse unit and an enemy unit within 24" and visible to it; friendly Tyranids models within 6" of that Synapse unit re-roll Hit rolls of 1 and Wound rolls of 1 against that enemy.
1CP. Attacks against a targeted Synapse unit have their Armour Penetration worsened by 1 until the attacker finishes. Reprinted in the Faction Pack's Rules Updates.
1CP. A Tyranids unit within Synapse Range that Fell Back this phase is still eligible to shoot and declare a charge.
1CP. Just after an enemy unit fails a Battle-shock test, a Synapse unit within 12" rolls six D6: each 3+ inflicts 1 mortal wound.
Tyranids Synapse model only. Enemy units within 9" of the bearer have their Leadership worsened by 1, feeding Battle-shock failures.
Tyranids Synapse model only. Enemy Reserves cannot be set up within 12" of the bearer, plus a once-per-battle 4+ to stop a Strategic Reserves unit arriving in the first or second battle round.
Tyranids Synapse model only. Subtract 1 from the Damage characteristic of each attack allocated to the bearer.
Tyranids Psyker model only. Improve the Strength and Armour Penetration of the bearer's psychic weapons by 1.
Cheap, mobile Synapse anchors that stretch the Imperative's coverage across the board.

How to play Synaptic Nexus in 11th edition — the 2-DP Synapse-network detachment with round-long army-wide Imperatives, the Tyranid answer to a Gladius.
Sprue Sentry strategy commentary for 11th edition, not official rules. Games Workshop updates points and rules regularly; always confirm against the current official rules and latest update before a game.
Synaptic Nexus is the Tyranids flexible buff detachment: a 2-Detachment-Point package that hands your whole synapse-covered army a chosen army-wide buff each round — the Tyranid equivalent of a Space Marine Gladius. It reflects Warhammer 40,000 11th edition.
This is SprueSentry strategy commentary, not official rules. The Tyranids Faction Pack version 1.2 reprints the Reinforced Hive Node stratagem, which is confirmed against that document. The rest of the lists come from the 10th-edition codex, cross-checked across two independent community rules mirrors. We re-checked the pack's amendments on 27 August 2026 against version 1.2, the release that arrived with the 26 August 2026 balance update. DP costs and points move with dataslates, so confirm them in the Warhammer 40,000 app before a game.
At the start of each battle round you can pick one Synaptic Imperative — each selectable only once per battle — and until the end of that round every Tyranids unit within Synapse Range benefits:
Three Imperatives, once each, over five rounds: you get three good rounds and two flat ones, so plan which round each one lands on. It's a flexible, melee-leaning buff engine that rewards a Synapse-dense list — the more of your army sits in range, the more the round-long Imperative is worth.
All six cost 1CP:
Choose it for a flexible, melee-leaning buff army — board control and a durable, aggressive swarm rather than pure regeneration or a monster-mash. It's strongest when your list is Synapse-dense so the round-long Imperative reliably covers your battleline, and best early-to-mid game while your network is intact. At 2 DP it leaves 1 DP for a support.
Sample gameplan: build around 3-4 Synapse projectors (a Neurotyrant plus Warriors and a Hive Tyrant) so the whole army sits in range. Turn one, call Synaptic Augmentation for a 5++ wall on a big gaunt block; on aggressive turns call Surging Vitality to throw Hormagaunts up the board or Goaded to Slaughter before a big melee. Use Imperative Dominance to double an Imperative on a key unit, Reinforced Hive Node to blunt AP, and The Smothering Shadow plus Dirgeheart to farm mortal wounds off Battle-shock.
2 DP, leaving 1 DP at a 2,000-point game for a support detachment.
Synaptic Imperatives: at the start of each battle round you can select one army-wide buff, active until the end of that round for every Tyranids unit within Synapse Range. Synaptic Augmentation grants a 5+ invulnerable save, Surging Vitality adds 1 to Advance and Charge rolls, and Goaded to Slaughter adds 1 to melee Hit rolls. Each can only be selected once per battle.
Synapse projectors above all — the Neurotyrant, Tyranid Warriors and a Hive Tyrant — so your whole army stays in range of the active Imperative, plus big Termagant and Hormagaunt blocks that convert the buffs into durability and threat range.
In spirit, yes — it's a flexible, army-wide buff detachment rather than a niche gimmick. It rewards a Synapse-dense list and patient play, and falls off as the game opens up and your Synapse projectors die, so protect them.
