Tyranids

How Tyranids play

Tyranids are the adaptive swarm army, and one of the most internally varied factions in the game. A Tyranid list can be a genuine horde of cheap gaunts, a small force of enormous monsters, or a mix — and these play so differently that Tyranid advice from another player may not apply to your list at all.

The synapse system is the connective tissue. Units near a synapse creature function properly; units cut off from it degrade. That gives the army a positional structure that most horde forces lack, and it makes your synapse creatures priority targets for both players.

The army excels at applying pressure everywhere at once. Between fast gaunts, burrowing units and monsters, Tyranids can threaten more of the table simultaneously than most factions.

Building a Tyranids army list

Decide swarm, monsters, or a deliberate mix. All three work, but they want different detachments and different play, and drifting between them produces a list with no plan.

Protect synapse. A list with two synapse creatures is a list that stops working when your opponent kills two things.

Tyranids FAQ

What is synapse and why does it matter?

Synapse creatures keep nearby Tyranid units functioning properly; units outside their influence degrade. It gives the swarm a positional structure and makes synapse creatures high-priority targets.

Should I play a Tyranid horde or a monster list?

Both are viable and they play completely differently. Hordes control ground and absorb losses; monster lists hit far harder but face the usual low-model-count objective problem. Pick one and build into it.

Are Tyranids good for beginners?

Reasonably. The army forgives losses and the plan is intuitive. The synapse system adds a layer of positional discipline that takes a few games to internalise.
