We all need Intrusions


Managed interventions in the Narrative

Playing with the Plot

Why do I want an Intrusion?

In a recent game of HeroQuest 2, I experimented with having Wyrd cards to use as a GM. Wyrd cards are our House Rules variant of Bennies, Fate Points and the HeroQuest application of Experience points, all rolled into one. I found it empowering to be able to intervene in the plot in the same way that the Players can, so I wanted to explore this idea further.

This is very similar to the GM Intrusion rule as outlined in Monte Cook’s Numenera, but the concept applies to any narrative game. Monte devotes several pages to explaining Intrusions in the Numenera Core Rules.


The Principles of Intrusion

So what IS an Intrusion?

An Intrusion is where the GM intervenes in the Narrative to heighten the drama or conflict, typically by worsening the current situation. Thus, the Warrior drops her sword, the Rogue triggers a trap or the Mage opens a Planar Portal. To compensate for this, the (most) affected Player receives a Bennie (or system equivalent reward) AND gains a second one to hand out to another Player of their choice. In Numenera, a Player may decide to deny the Intrusion, but thereby does not receive the rewards.

While I like the idea that Players have to weigh up the choice of accepting an Intrusion or not, this does not always fit with my plans for the plot, such as the Escaping Villain trope below. Therefore, I suggest dividing Intrusions into two categories;

1   Dramatic Intrusions

These are the standard Numenera Intrusions, that a Player can choose to refuse. Examples would be Ascanius dropping his cleaver in the middle of combat, or Ragnarr’s lightning spell rebounding onto the other Heroes.

2  Plot Intrusions

These Intrusions are the ones that the GM can force through. This is not to ride roughshod over the Players, but rather to ensure that an important plot twist will happen. Such enforced Intrusions require careful handling and a degree of trust from the Players.


What Intrusions can do for Your Game

Why should I use Intrusions?

Intrusions are a perfect fit for any narrative game, and thus make a good Rules Widget for your game. The benefits are as follows;

  • Intrusions give the GM a controlled way to guide the plot.

Obvious, but this is the core of what Intrusions do. We all need ways to guide the plot, not to railroad the Players, but to weave more drama and excitement into the game. When aiming for a cinematic feel, you need to add plot twists and complications to the story. Intrusions allow you to do exactly that.

  • Player buy-in

Of course, GMs have been manipulating events for as long as there have been GMs. Yet, by codifying the process as an Intrusion, making these twists part of the rules, then the process is legitimised. Plus, when Players receive a reward as a direct result of the Intrusion, they will be more accepting of the process.
While some Players will accept these minor reversals as part of the drama of the game, others may need to be bribed.

  • Plot Intrusions facilitate certain types of event

Finally, Intrusions simply allow the GM to achieve a broader selection of events in the game. No longer will you need to fudge circumstances or rolls, instead simply declare an event to be a Plot Intrusion, and thus side-step Player intervention at a crucial moment. For example;

    • The Villain escapes!

I have tried several times to ensure that this happens early in the story, but the Players always overwhelm the villain. I want to follow the traditional plot of an early encounter with the villain, who gloats and leaves, only to be defeated later. Intrusions are a perfect way to facilitate this trope.

    • More Guards burst through the door!

How many times have you run a combat, only for the Players to breeze through it without raising a sweat? An Intrusion legitimises the arrival of reinforcements, prolonging an exciting combat and creating the desired level of tension.

    • Capture the Heroes

Having the villain capture the Heroes, only to reveal his plans and foolishly allow the Heroes to later escape is a common trope, especially in the earlier James Bond films. Such an event is notoriously hard to pull off in RPGs, but simple with a Plot Intrusion.

    • Make the Cool Power work

Another frustrating situation is where you have a villain or monster with a cool power, only to fail to make it work however many times you try to use it. Once again, an Intrusion will legitimise the GM forcing this to succeed. This should be used rarely, and is best restricted to iconic abilities, but remains a useful option.



With great power comes great responsibility.

Obviously, you must not abuse the system. The Players need to trust the GM, so use Intrusions sparingly. Even though the method is justified to the Players in advance, and they can be rewarded in the process, care is still needed. Perhaps one Intrusion per hour of gameplay is a fair use of the ability.

Likewise, if the Players see that you are using Intrusions to Maximise Game Fun, then their tolerance for them will increase. So, the trope of the villain who escapes, only to be beaten later, serves as a good example. To balance out the Players’ frustration at having the villain escape, be sure to give them the satisfaction of later defeating the villain. Later in the same scenario, or later in the campaign, just make sure that you give the Players this payoff.



Intrusions are a welcome tool for a narrative game, just use them wisely and Maximise the Gaming Fun. To read more about Intrusions, see the Numenera Core Rules.
