Doom The Dark Ages Revelations DLC Chain Spear guide: Fix the ?? Bug

The release of the highly anticipated expansion has brought brutal new weapons to the Slayer's arsenal, but a frustrating game-breaking bug is stopping many players in their tracks. If you are staring at a confusing "??" on your screen when trying to use the new hook mechanic, this Doom The Dark Ages Revelations DLC Chain Spear guide is exactly what you need. Navigating the demonic hordes in the new content is tough enough without technical glitches, which is why our Doom The Dark Ages Revelations DLC Chain Spear guide will walk you through the exact steps to restore your missing button prompts.

By fixing this input error, you can get back to ripping and tearing your way through the medieval hellscape. Beyond just troubleshooting, we will also dive into the combat mechanics, strategies, and best practices for mastering this incredible new weapon.

Understanding the Chain Spear Bug in Revelations

The Revelations DLC is a massive, free update for owners of the Premium Edition of Doom: The Dark Ages. It bridges the gap between the medieval setting of the prequel and the high-octane mobility of Doom Eternal. The centerpiece of this expansion is the Chain Spear, a brutal new tool that functions similarly to a Meat Hook, allowing the Slayer to grapple toward enemies and traverse the environment.

Unfortunately, the expansion launched with a glaring issue. According to extensive community reports and player experiences, console players on both PlayStation 5 and Xbox Series X/S are encountering a bug where the Chain Spear lacks a designated button prompt. Instead of showing a button to press (like L2 or Left Trigger), the game displays a cryptic "??" symbol.

This happens primarily to players who have an existing save file from the base campaign prior to the DLC's release. Because the game does not automatically assign the new input to old control profiles, the action is left unbound. Without the ability to throw the Chain Spear, progression through the DLC is impossible.

Step-by-Step Fix for the Button Prompt Error

Fortunately, you do not need to wait for an official patch to get back into the action. Fixing the missing input is a straightforward process that forces the game's engine to refresh its controller bindings.

If you are stuck at the tutorial prompt or unable to grapple across a chasm, follow the steps in this Doom The Dark Ages Revelations DLC Chain Spear guide to reset your controls. You do not need to delete your save file or reinstall the game; a simple menu toggle will resolve the issue.

Here is the exact method to restore your Chain Spear button prompt:

1. Press the Start/Options button to open the main Pause Menu.
2. Navigate to the Settings tab.
3. Scroll over to the Inputs section.
4. Locate the Slayer Controller Presets option.
5. Change the preset from Default to Southpaw.
6. Immediately change it back from Southpaw to Default (or whatever your preferred custom preset was).
7. Exit the menu and return to the game.

By forcing the game to switch input presets, it automatically populates any missing keybinds with their intended default buttons. You should now see the correct trigger prompt instead of the "??" symbol, allowing you to throw the Chain Spear and pull yourself toward the demonic threat.

How to Master the Chain Spear in Combat

Now that your controller is properly configured, it is time to unleash the full potential of your new weapon. As outlined in this Doom The Dark Ages Revelations DLC Chain Spear guide, the weapon is much more than a simple traversal tool. It is a fundamental shift in how the Slayer approaches combat in the medieval setting.

The Chain Spear acts as a massive mobility enhancer. When fired at a heavy demon, the spear digs into their flesh, allowing you to rapidly pull yourself into point-blank range. This is incredibly useful for setting up devastating melee finishers or lining up a perfect blast with your Shield Saw or heavy shotgun.

Furthermore, the Chain Spear applies a brief stagger to lighter enemies. If you are overwhelmed by fodder demons, quickly grappling one can interrupt their attack animation, giving you a split-second window to reposition. Mastering the mid-air momentum is crucial. By jumping right before the Chain Spear fully retracts, you can launch yourself over the enemy, raining down fire from above and avoiding ground-based area-of-effect attacks.

Comparing the Chain Spear to the Meat Hook

Veterans of the modern franchise will immediately recognize the DNA of the Chain Spear. It serves as the mechanical predecessor to the Super Shotgun's Meat Hook from Doom Eternal. Understanding the subtle differences between the two is a core component of this Doom The Dark Ages Revelations DLC Chain Spear guide.

While the Meat Hook in Doom Eternal was permanently attached to a specific firearm, the Chain Spear in The Dark Ages operates as an independent piece of equipment. This means you can initiate a grapple while simultaneously readying a different weapon, offering unprecedented flexibility in your loadout combinations.

Additionally, the Chain Spear has a slightly heavier, more grounded feel. The physics engine in The Dark Ages emphasizes the sheer weight and brutality of the Slayer's medieval armor. As a result, the pull of the Chain Spear feels more deliberate. It doesn't instantly snap you across the map; instead, it drags you with unstoppable momentum, tearing through destructible environments along the way.

Essential Tips for the Revelations DLC

The Revelations expansion ramps up the difficulty significantly, introducing new enemy variants and complex arena designs that demand mastery of your entire toolkit. Having a working Chain Spear is only step one.

First, never stop moving. The arenas in the DLC are designed with verticality in mind, specifically to test your use of the new grapple mechanics. If you stay on the ground, you will quickly be cornered by the new heavily armored demonic infantry. Use the Chain Spear constantly to zip between elevated platforms and isolated enemies.

Second, integrate the Chain Spear into your resource management loop. While it doesn't drop armor automatically like the flaming Meat Hook, pulling yourself into a staggered enemy guarantees a successful glory kill or Shield Saw execution. Use this to keep your health and defensive resources topped off during frantic firefights.

Finally, experiment with your controller layouts. Now that you know how to fix the binding bug, you might find that the default controls don't suit your playstyle. Many players report that moving the Chain Spear input to a bumper rather than a trigger allows for faster reaction times during intense aerial combat.

Frequently Asked Questions (FAQ)

Why does my game show "??" when I try to use the new weapon? This is a known bug affecting players who had save files from before the expansion launched.
