Halo fans, get ready for a terrifying return to the Flood’s origins. 343 Industries and publisher Simon & Schuster have officially confirmed Halo: Parasite’s Wake, a new novel from acclaimed horror author Tim Lebbon, set to release in 2026 as part of the franchise’s 25th anniversary celebrations.
This isn’t a video game – it’s a full-length novel that dives deep into the events of the original Halo: Combat Evolved (2001), focusing on the horrifying Flood outbreak on Installation 04 from a fresh perspective.

Plot Overview (Spoiler-Free)
The story unfolds in 2552 during the chaos of the UNSC Pillar of Autumn’s crash-landing on the ringworld Halo. Staff Sergeant Marvin Mobuto leads a squad of imprisoned Marines (facing charges like desertion and murder) back to the crash site to regroup with allies.
But the Covenant isn’t the only enemy. As war rages across the ring for control of the installation’s weapons and secrets, a far more terrible threat emerges from deep within Halo’s underworld – the Flood parasite awakens and transforms the conflict into a desperate battle for survival.
The novel promises visceral horror, survival tension, and new insight into how the Flood spreads and overwhelms both human and Covenant forces.
