Carnifexes are hulking, powerful Tyranid creatures used as living battering rams. They are often armed with the most powerful Tyranid Bio-weapons, and are used in shock assaults, spaceship boarding actions, massed battles, and for battering through fortified positions and tank formations. Carnifexes excel at thunderous charges, where their immense bulk is used to crush or smash through any opponent or obstacle. They are not as swift as other Tyranid creatures but their brute force more than makes up for this. A Carnifex's stampede takes time to build force as their incredible alien musculature strains to propel it forward.
