Crusher Stampede: The 11th-Edition Tyranids Big-Monster Detachment

Your Tyranids Monster units get +1 to Hit while below Starting Strength and, on top of that, +1 to Wound while below half strength — so your beasts become more dangerous as they take casualties. Crucially, a Monster unit at full Starting Strength adds 2 to its Objective Control, patching the classic weakness of a monster list: actually holding objectives. It's a detachment that converts incoming damage into offence and lets big models score.

• Rampaging Monstrosities (Fight) — a Monster unit re-rolls Hit rolls. Your reliability button on the key combat.
• Massive Impact (Charge) — after a Monster charges, roll six dice against a target; each 4+ is a mortal wound. Alpha-strike damage on the charge.
• Swarm-Guided Salvoes (Shooting) — a Monster's ranged attacks gain Ignores Cover and ignore hit modifiers. Turns a Tyrannofex or Exocrine reliable.
• Savage Roar (defensive) — force a Battle-shock test and -1 to Hit on an enemy, blunting a counter-attack.
• Untrammelled Ferocity (Movement) — move a Monster over terrain and models.
• Corrosive Viscera — a destroyed Deadly Demise Monster deals maximum mortal wounds.

• Ominous Presence — +3 Objective Control on the bearer, doubling down on the detachment's scoring fix.
• Monstrous Nemesis — +1 to Wound against Monsters and Vehicles, your answer to enemy armour and mirror monsters.
• Enraged Reserves — if the bearer dies in melee, on a 3+ it fights before removal.
• Null Nodules — a once-per-battle Feel No Pain 5+ against Psychic attacks.

• Carnifexes / Screamer-Killers / Old One Eye — the core big-beast bodies; Old One Eye buffs nearby Carnifexes and carries enhancements.
• Norn Emissary / Norn Assimilator — durable heavy hitters that threaten armour and hold objectives at full strength.
• Tyrannofex / Exocrine — Monster shooting platforms improved by Swarm-Guided Salvoes.
• Haruspex / Maleceptor / Tervigon — tanky monsters that trigger Enraged Behemoths as they take wounds.

Take it for a low-model-count, all-monsters army that wants to brawl. It converts incoming damage into offence — surviving beasts hit harder as their unit shrinks — and the +2 OC at full strength finally lets monsters score. At 2 DP it leaves 1 DP for a support like Warrior Bioform Onslaught or Ambush Predators.

Sample gameplan: deploy a wall of monsters and use Ominous Presence and the full-strength +2 OC to contest objectives early. Push forward; as multi-model Monster units (a Carnifex brick) drop below Starting Strength the +1 to Hit kicks in, and below half the +1 to Wound stacks — wounded units become deadlier. Use Untrammelled Ferocity to reposition, Rampaging Monstrosities on the key combat, Massive Impact for a charge alpha, and Savage Roar to blunt counter-attacks.
