Mad Cave Announces Epic Crossover Event, Endless Night!

When the sun never rises, the shadows hold every secret…

Get ready for the ultimate mash-up of high-adrenaline action, gritty noir mystery, and supernatural horror!

This summer, Mad Cave Studios invites readers into the shadows with ENDLESS NIGHT, a genre-smashing collision of archetypal heroes by celebrated writer Mark London (Battlecats, Hunt.Kill.Repeat.) and acclaimed artist Tom Derenick (Justice League)!

It’s brooding cityscape, morally complex figures, and relentless descent into mystery, Endless Night is a defining and compelling event in Mark London’s Underworld interconnected universe, drawing four of its most captivating characters into an unholy union against sinister power-brokers and ancient evils—and in so doing, binding them irrevocably together to set the stage for future adventures.

With colors by Juancho Velez and letters by Simon Bowland, Endless Night #1 debuts with two striking covers: Cover A by Chris Weston (The Filth, Judge Dredd) and Cover B by Declan Shalvey (Moon Knight, Bog Bodies), each capturing the ominous tension of Mark London’s Underworld.

“Endless Night, our inaugural crossover piece for the Underworld universe, and it’s where my childhood dreams have taken form. It’s where the relentless rhythm of Revolution 9, the eerie whispers of Hour of the Wolf, and the gritty vibes of Exit City converge. These worlds, steeped in action, horror, and noir, are the essence of my creative soul and the foundation upon which Mad Cave Studios was built. Growing up, these narratives fueled my imagination, and now they have become my reality. Through this crossover, I aimed to explore the delicate dance between light and shadow, and how they shape the human experience.”
