Warhammer 40,000 Wrath & Glory RPG Core Rules
From the back of the book:
Roleplaying in the Grim Darkness of the 41st Millennium
This accursed Age needs heroes more than ever before. Shattered by the Great Rift, the galaxy is on the brink of oblivion and madness. There are those who fight for a shred of hope, a glimmering promise that this millennium may yet endure.
What will you fight for? What will you sacrifice? Enter a galaxy full of danger and mystery, plagued by the star-spanning schemes of the Dark Gods. You will defend the last bastions of civilization against a rising tide of corruption. You will explore ancient ruins of races long-vanished. You will uncover lost secrets and devious schemes.
This is a game of danger and mystery. This is a game of action and adventure. This is a game about the struggle to hold back the doomsday clock from striking midnight for an entire galaxy.
This is your story of wrath and glory.
