Bury your foes in a relentless tide of claws with the Onslaught Swarm, one of the most terrifying assemblages of Tyranid monstrosities ever stuffed into a box. A massive Norn Emissary joins up with a Winged Hive Tyrant – which can also be built as a ground bound Hive Tyrant or Swarmlord – to lead a tide of 20 leaping, scything Hormagaunts and 10 ravening Genestealers, with a pair of Ripper Swarms to boot.
