Alternative Combat Systems in Cortex Prime, Part III: Holding the Line and Coordinated Actions

For the previous part of this series, click here.

In this part of the series, I’m going offer two (sub)systems for handling particular types of combat situations; the first riffs off of the “Bloody Versus” while the second utilizes a nuanced form of “Narrative Combat.” Let’s get to it:

Timed Defensive Actions

“Mal: Zoe…are you here?
Zoe: Do the job, sir.
Mal: You hold. Hold till I’m back.”

Serenity, 2004

This system can be used for situations where the characters are fighting a defensive battle against waves of attackers while keeping mechanics streamlined compared to character-by-character combat.

The GM needs two things at the start of the engagement (which can be set in adventure prep). The first is the dice pool used to represent the attacking force. Create this as you would any opposition, starting with a pair of difficulty dice representing the base quality of the attackers and adding dice for a Distinction and other applicable Traits. If the size of the attacking force warrants it, consider using the Scale rules, but bear in mind genre as well as the close narrative—if you’re playing a game involving special operations forces in an 80’s-style action movie, they’re probably expected to absolutely wade through the enemy and Scale would not be appropriate.

The second preparatory item is a mechanism for tracking the enemy’s fighting ability or the amount of time the PCs must hold out before help arrives. Depending on your damage system, the enemy force may have a die step that is whittled down, may have a Stress or Trauma die that is stepped up, or may have a damage track. If the conflict is a matter of holding out for time, you can set up a track or a “clock” in the style of Powered by the Apocalypse games.

Variant: Random Timing: If you want to add additional drama (and stress to your players), you can take a cue from miniature wargaming and have the conflict last for a random number of turns. To do this, decide upon a definite number of turns the conflict will last (e.g. “at least 3”). After the predetermined amount of time has run, roll a die at the end of each turn to determine if the event that would end the conflict (air support or reinforcements arrive, another team manages to destroy the attackers’ path to the characters, etc.) occurs. Use whatever die size you’d like and start with a chance of occurrence you feel comfortable with given the difficulty of the engagement for the characters. For example, you could start with a D6 and the conflict ends on a result of 6. For each time this die is rolled and does not meet the threshold, reduce the threshold by one. In the example above (d6 vs. 6), if the conflict doesn’t end on the first post-turn roll, in the second turn you roll d6 vs. 5, and so on.

In each turn, each player character rolls the appropriate pool against the Opposition Pool. For each PC who fails, that PC takes stress, trauma or injury depending on the damage system you’re using and how deadly your game is overall (I’d personally not recommend immediately applying damage that takes significant time to heal unless your setting has ways to circumvent that—magic or tech—or this defensive action takes place as part of the climax of the story where the stakes need to be turned all the way up.)

Assign the PCs their own track that represents their ability to hold their position. For each failure against the Opposition, mark a box along the track. When the track is full, the PCs are overrun by the enemy.

Variant: King of the Hill: With a slight modification, this system can be used to simulate a “king of the hill” scenario where both sides of the conflict are attempting to take and hold the same location. In this case, build a track with a center point, and have the character’s net successes or failure move the track in their favor or against their favor. When the track has filled on one group’s side, they have managed to seize the terrain with a strong enough position that the other group may not immediately attempt to take it back. If you want to limit the amount of time the conflict can last, remove a box from either side of the track every so many rounds as attrition and exhaustion take their tolls. Of course, one side or the other may take injuries enough that they abandon the field, and that’s okay, too.

One potential issue with this system is that it does not necessarily spotlight the actions of any particular PC, but this is relatively easy to overcome. You can plan certain events between the collective rolls in certain turns and give a particular player a chance to address that particular event before it affects the overall situation.

As an example: say you’re running a modern military campaign with special forces operators holding their position until requested air support is able to decisively end the confrontation. Between the collective rolls representing the characters’ defensive actions, let’s say a tank rolls up and begins to train its main gun on the characters’ position. The player character with the anti-tank weapon gets to take a shot to eliminate the newcomer before it becomes a problem. If this character’s attack roll is successful, the tank is destroyed and does not factor into the opposition in the next collective test. If the attack fails, add another die to the opposition pool representing the need to take cover from tank shells in addition to the rest of the assault. Obviously, the specifics of such opportunities should be drawn from the various abilities and foci of the characters to give each a time to shine, if not in the same engagement then over the course of the adventure.

If the characters have time to prepare for a this kind of defensive action, allow them to create Assets or Resources (i.e. expendable assets) for the conflict. Instead of applying damage to a character who fails an opposition test, the opposition pool’s success die could be used to eliminate or step down an Asset or Resource. In this way, not only do these Assets and Resources provide some benefit to the characters’ rolls, but some additional “armor” to keep characters in fighting shape for future conflicts. Whether an Asset or Resource applies to all PCs’ rolls in a turn or to only some is a judgment call for the GM to make based on context.

Variant: Defend Actor: This system can also be used to simulate situations in which some of the PCs are providing cover and defense for others to complete a non-combat action. Perhaps one or more of the characters needs to complete an ancient ritual while the rest of the party defends from attacking orcs. In this case, rather than keeping a track for the timing of the defensive action, create a track for the number of successes needed for the necessary task to be completed. For each character addressing the non-combat task, a success checks one box on the track and a heroic success checks two. If multiple characters could reasonably be assigned to either defense or the non-combat action, modify the defensive opposition pool (in conversation with the characters so that they can collectively decide where they want to put everyone) based on the number of defenders. You can use scale to do this, but the addition or removal of a die will probably be best for most situations.

If the characters are overrun, they must retreat from their position without completing the appointed task. If the task is successful, it should have ending the onslaught as a narrative consequence (in addition to the story-moving effects).

Coordinated Actions

“Either you’re part of the problem, or you’re part of the solution, or you’re just part of the landscape.”

-Sam, Ronin, 1998

This system is suited for those perfectly choreographed operations that depend on everyone completing their individual tasks at the right time so that the entire operation goes off without a hitch. These are your Mission Impossible montage ops, your small-unit actions to waylay a traveling vehicle and extract a VIP before making a getaway, your high-intensity but short action scenes where everyone has a particular role to play.

I used to love RPG sessions (particularly in Shadowrun) where the players would sort through maps and security schedules, lists of equipment and mission objectives to come up with an elaborate plan. But two things would either happen: (1) the plan needed so much detail that one of the players got tired of it all and decided to kick down a door and start shooting, or (2) playing out the elaborate plan took us three more sessions and everyone got tired of it. These rules are designed to condense the planning to the most exciting parts and play it out with the kind of speed and intensity usually reserved for film.

And really, it’s just an adaptation of the Narrative Combat rules from the previous post, with an added cue from the “Engagement Roll” of Blades in the Dark.

Here’s how we do it: the player characters have their objective. They’ve gathered the necessary intel and the equipment necessary to achieve the objective (perhaps setting up Assets for their various rolls). Then, the PC team plans the op, assigning discrete actions to each PC, like so:

It’s a snatch and grab on a moving vehicle with a target guarded by professionals. PC #1 is the driver, both approach and getaway. Number 2 is the bag man, tasked with extracting the target. Numbers 3 and 4 are shooters to provide cover for the extraction. PC #5 is a hacker whose task is to change streetlights to the advantage of the group, to jam any communications from the target and bodyguards, and to wipe any surveillance footage from city cameras. So, each character’s actions might be described by the following:

  • PC 5 modifies the street lights to box the target vehicle in.
  • PC 1 drives at high speed to block the target vehicle from escape.
  • PC 5 jams communications.
  • PCs 3 and 4 engage the bodyguards, suppressing them or eliminating them as necessary.
  • PC 2 engages the target and pacifies him.
  • PC 2 puts restraints on the target and gets him into the PC vehicle.
  • PCs 3 and 4 make a fighting retreat to the vehicle and get inside.
  • PC 1 drives off at high speed and uses evasive driving to lose any tails.
  • PC 5 wipes security footage to ensure that the PCs aren’t followed by the authorities.

As with Narrative Combat, each individual PC’s various actions are given sequential difficulty thresholds, and then each player rolls against their opposition (I think the best way to do this is for the opposition pools to be created in dialogue with the players, but the opposition roll results to be withheld until the GM narrates the results).

If all players meet all thresholds, the operation goes off without a hitch—the PCs have nabbed their target and taken him to their hideout without anyone being able to identify or follow them.

If any of the players fail, however, there are consequences. If there are only some minor failures—perhaps Player 3 fails his final threshold to return to the vehicle, then you can assign a Complication or injury and the operation remains successful as a whole. If a major threshold is missed (say PC 2 fails to pacify the target), or if there are multiple missed thresholds, then we use the collective rolls in the style of Blades in the Dark’s “engagement roll.”

If you’re not familiar with that mechanic, the engagement roll is a single roll intended to move past the boring bits of a heist and straight onto the excitement, its result sets the narrative positioning of the players as we jump in media res into their action by establishing whether things are going very well, very poorly, or middling at the time play of the heist begins.

In our situation, there’s a bit more complexity for the GM as she’s interpreting separate roles to create a cohesive narrative position for the transition into another type of mechanic to continue the action—this may be turn-by-turn combat, another alternative combat, or some sort of contest or conflict to represent the characters’ escape after things go wrong.

In the example above, with PC 2 failing to subdue the target, the GM might determine that the situation is thus as play moves out of the narrative combat system and into the alternative format: The target, though groggy from a blow to the head, is escaping on foot through a crowd of innocent bystanders. PC 2 is giving chase. PC 3 and 4’s successes mean that at least none of the bodyguards are following after PC 2, but now the rest of the group needs to get out of the middle of the road, evade detection, re-establish communications with PC 2 and find a way to meet up before the local authorities or reinforcements find PC 2 and/or the target first. Had the other PCs missed significant thresholds as well, additional complications would be added to the narrative as we “zoom in” to the aftermath of the botched operation.

Unlike the “generic” Narrative Combat system from the last post, there’s no need to establish consequences for each threshold of each roll in this particular use of the mechanic. The GM can wait until seeing all the rolls to weave together the results, assigning consequences only where necessary.

This system can be used for all sorts of character actions that are planned and prepared in advance. In addition to examples above, generic heists, ambushes, coordinated cons and other exploits can use this alternative to turn-by-turn resolution.

Conclusion

Two more tools for the toolkit in the bag. I think that both ideas are flexible and adaptable enough to accommodate a wide variety of narrative needs. Still, I’ll be adding to this series as I think of additional systems to streamline various types of action sequences or combats.

Again, I can’t stress enough that these are tools to be used alongside the conventional methods for resolving combats and conflicts based on what best fits any particular situation and the play style of the table.
