Highlights

This desert has teeth.

A year after the fall of Resolv Corp, the Hellsings have scattered. The head of the Las Vegas chapter has gone missing. Their safe houses are ash. And tearing across the wastelands of post-apocalyptic America comes the Echo Legion, a paramilitary nightmare riding genetically engineered dinosaurs into battle.

AT THE TABLE
Players: 2-4
Session Time: 90 Minutes
Length: 4 Sessions

Led by the brilliant and unhinged Exus Grievves, a scientist who rewired his own brain for power, the Legion has one goal: total domination. At its vanguard flies Vexeinne Thorne, a bloodthirsty commander who rules the skies atop GrymWhyskers, a weaponized Quetzalcoatlus. With super-mutant enforcers and raptor cavalry at her back, she's the nightmare between the Hellsings and survival.

Now a new generation of Hellsings must rise: a trickster with a bag of flashbangs, a dead-eyed sniper, a getaway driver with chips in one hand and a wheel in the other, a glider spy drawn to danger like a moth to flame, and a brawler who hits where it hurts, then patches you up after. But they're not alone. The Neon Jackyls, a rival gang who once fought the Hellsings over every scrap of turf, are trapped in the same outpost. They make for uneasy company. Old grudges run deep, ammo's low, and there's no turf left to fight over. Not when the world outside has teeth.

You’ll need to wrangle dinosaurs, rescue hostages, and outrun extinction, all while protecting a convoy of orphans and a baby pterosaur with a taste for Junior Mints.

Strap in. Pick your ride. Roll out.

Death by Dino is a complete adventure for the 321RPG system featuring vehicular combat, dinosaur wrangling, and enough post-apocalyptic chaos to fill a drive-in double feature.
