Hallowed Nightmares is a Halloween Tactical Alert that returns to Warframe in 2026, featuring a special encounter against the pumpkin-headed Jack O’Naut.
The mission takes place on Earth, where players must navigate an Infested forest while their usual weapons and Warframe abilities are disabled.
Completing the event rewards several Halloween-themed items, including the Jack O’Naut Keychain Sugatra, before Hallowed Nightmares ends on November 2, 2026.
What is Hallowed Nightmares?
Hallowed Nightmares is a limited-time Sabotage mission that takes place on Earth, featuring Infested enemies and a unique boss encounter against Jack O’Naut.
Players must complete objectives throughout the forest tileset before reaching the boss, with their weapons and abilities unavailable during the mission.
Instead of relying on powerful Warframe builds, players must use unarmed attacks and environmental hazards to progress and eventually defeat Jack O’Naut.
How to Start Hallowed Nightmares?
Open Navigation aboard your Orbiter and select Hallowed Nightmares from the Event tab, where it appears as a Level 1–2 Sabotage Tactical Alert.
Select the mission to begin, which takes players to an Infested forest tileset on Earth with several objectives leading toward Jack O’Naut.
No special resources or entry items are required to start the mission, and players can access it directly through the event listing.
How to Complete Hallowed Nightmares?
Upon entering the mission, players must make their way through the forest while avoiding Infested enemies, since their weapons and Warframe abilities are disabled.
Follow the objective markers until reaching the consoles, which must be interacted with to obtain the canisters required to open the locked door.
This process must be completed twice, with players collecting and delivering the required canisters to unlock the passage leading to the boss.
Once the door opens, proceed into the next area to encounter Jack O’Naut, who must be defeated before the mission can be completed.
How to Defeat Jack O’Naut?
Jack O’Naut is a pumpkin-headed Infested Juggernaut that cannot be defeated using ordinary attacks, requiring players to damage him through environmental hazards.
Throughout the arena are stacks of three pumpkins that can be destroyed using unarmed attacks, causing them to release flames that damage nearby enemies.
Lure Jack O’Naut toward one of these pumpkin stacks while avoiding his attacks, then destroy the pumpkins when he moves close enough to be caught in the fire.
The resulting flames create a burning area that damages Jack O’Naut, making it important to position him correctly before triggering each explosion.
Continue moving around the arena and destroying additional pumpkin stacks whenever Jack O’Naut approaches them, repeating the process until his health is depleted.
Once Jack O’Naut has been defeated, follow the extraction marker to finish the mission and receive the completion rewards.
Hallowed Nightmares Rewards
Completing Hallowed Nightmares grants four guaranteed rewards, which are delivered together through an inbox message from the Lotus after successfully finishing the mission.
The rewards include:
- 50,000 Credits
- Jack O’Naut Keychain Sugatra
- Jack O’Naut Recall Glyph
- Noggle Statue – Manic
These are one-time rewards, meaning players only need to complete the Tactical Alert once to receive the entire bundle.
The Jack O’Naut Keychain Sugatra is the new reward introduced for the 2026 event, while the other items have appeared during previous versions of Hallowed Nightmares.
Tips for Hallowed Nightmares
Avoid unnecessary fights with regular Infested enemies, as rushing toward the marked objectives makes it easier to complete the mission without weapons or abilities.
During the boss encounter, keep moving around Jack O’Naut and avoid standing directly in front of him, especially when attempting to destroy nearby pumpkin stacks.
Wait until Jack O’Naut approaches the pumpkins before destroying them, since triggering the flames too early may cause the boss to miss the burning area.
Use the available space to lure Jack O’Naut between different pumpkin stacks, allowing players to repeat the process without remaining exposed to his attacks.
Verdict
Hallowed Nightmares is a relatively short Tactical Alert that becomes easier once players understand how to complete the Sabotage objectives and defeat Jack O’Naut.
The boss encounter requires careful movement and proper use of the explosive pumpkins, as conventional attacks cannot deal the damage needed to defeat him.
Completing the event provides four guaranteed rewards, including the Jack O’Naut Keychain Sugatra, making it worth finishing before the event concludes.
