From Ashes

Noble Six has lost everything, sacrificing his only way off of Reach to save the last hope for humanity. He is supposed to die in glorious gunfire, but what if he didn't?

Doom Slayer is a being that possesses enough power that hell itself fears his name. Having awakened in UAC headquarters he is adamant on getting back to hell to finish what he started. But it's not hell that the argent portal sends him.

Two legendary killers will meet on the battlefield, altering the path both were destined to follow. Now both worlds begin to collide in a massive amount of blood and bullets. Friends will be made, enemies will be slain, and things will never be the same.
