Thank you for hosting this week's #TurnBasedThursday, @ninedotsstudio.bsky.social !
This week's update of Zodiac Legion is a deep dive into the research and development process of our combat system, especially when it comes to doing armor justice:

Let's turn my Tacticon presentation into a TLDW thread about medieval armored warfare on foot and overdesigning the gameplay mechanics of ZodiacLegion :

But we can fill the gaps with magic, or choose what we want to represent!
August 28, 2025 at 1:06 PM
Now let's address the part about the limits of our sources:
We have very little documentation about formation combat in armor:
- Chroniclers who wrote about battles didn't see them
- Knights who were into writing typically wrote about chivarly rather than fighting.
August 28, 2025 at 1:06 PM
As for the attrition/exhaustion factor, that's why we decided to represent our dungeons as a single protracted battle, instead of a series of micro engagements.

●spending time resting allows other enemies to ready themselves
●Enemies will also engage the player on their own
August 28, 2025 at 1:06 PM
As for weapon variety, I said one hander sucked against plate armor, BUT they allow you to carry a big shield, which makes protecting these vulnerable characters, like archers or mages much easier!
August 28, 2025 at 1:06 PM
You don't always need to penetrate armor to kill the knight inside, or wound him.
As for our legendary knights:
Geoffroi de Charny: killed as the French formation was broken at Poitiers
Jacques de Lalaing: killed by a cannonball shot.
Bayard: killed by an arquebus.
August 28, 2025 at 1:06 PM
Let's talk about Agincourt...
- Not everyone wore plate
- Most men-at-arms were defeated in melee
- A good part of them were captured (then executed)
- In a way, the strength of the longbow was forcing the enemy to attack :
"it takes but a single bush to break their ranks"
August 28, 2025 at 1:06 PM
That is why we made melee support central in the game, both in attack and defense.
It also stacks with a flanking bonus when you have opponents on all sides.
August 28, 2025 at 1:06 PM
Combat of the thirty: Similar set-up, but with 30v30 in Brittany:
- 4 French and 2 English down after hours of fighting
- They decided to take a break
- Then after a French squire remounted and managed to break the English formation, the battle was almost instantly over.
August 28, 2025 at 1:06 PM
Montendre was an arranged 7v7 during the HYW.
- The English chose to double-team DuChatel.
- This freed Archambauldde Villar assist Karonis against the English leader, Robert de Scale, who got quickly killed by a blow to the head.
- That allowed to "roll" the remaining English.
August 28, 2025 at 1:06 PM
Let's now zoom out a little, and see how fights between groups would turn out. In groups, grappling becomes much harder, unless you end up being isolated.
Medieval battles could take hours, so exhaustion was a pretty severe issue! Morale collapse was also how most battles ended.
August 28, 2025 at 1:06 PM
However, grappling is more complicated to animate, so we are still looking for a good way to represent/abstract it.
August 28, 2025 at 1:06 PM
So we are working on adding new alternate thrusting attacks for our 2 handed weapons, to let them thrust into the gaps of armor.
August 28, 2025 at 1:06 PM
Btw, the Half Sword game made a cool attempt at bringing these armored combat techniques to life in their demo :

Actually, grappling was very important, BUT it required some setup. Our knight, Jacques de Lalaing, managed to disarm an opponent and drive him away until the referee took pity of him and stopped the duel
August 28, 2025 at 1:06 PM
But I need to remind everyone that blunt weapons were NOT a magic can opener! You had to basically hit the head (or hand) with a strong blow, jam the point in a joint, or find a way to grapple your opponent to the ground with it.
August 28, 2025 at 1:06 PM
So, that is what we are doing in the game:
In a way, poleaxe is the offensive choice, while sword is more defensive, and halberd works better when supported.
August 28, 2025 at 1:06 PM
As for weapon selection:
Just take a poleaxe(it was the most popular weapon for knights on foot)!
Sword (the long and pointy variant) is also a reasonable choice, but you don't want to use a one hander.
Also, French knights typically used shortened lances.

Part 2: Weapons and techniques
August 28, 2025 at 1:06 PM
In ZodiacLegion, we use two layers per body part, each with its own encumbrance, coverage, and armor values. Any parts can be combined, and some — like the arms — have different chances of being hit depending on whether the attack is melee or ranged.
August 28, 2025 at 1:06 PM
Some games did cover armor in a detailled way already.
For instance, Cataclysm: Dark Days Ahead does simulate both coverage, armor, and limb specific encumbrance.
