Stronghold 4 Combat System: How Battles Work (2026)

Combat in Stronghold 4 is defensive siege warfare: you win by layering walls, towers, moats, traps and ranged units into kill zones, and by mixing unit types instead of spamming one troop. The game is not out yet — the official Steam page lists a December 7, 2026 early access release on Windows — so everything below comes from the free Steam demo and community playthroughs of it, which means exact balance and controls can still change.

The core loop

Every battle follows the same rhythm, whether in the campaign mission or skirmish mode:

1. Build an economy (wood, stone, food, gold) while the enemy is still away.
2. Raise fortifications — walls, a large gate, towers — along the enemy's approach.
3. Add ranged and melee troops, plus traps and oil pots at choke points.
4. Weather waves of attacks that grow progressively larger.
5. Either outlast the siege or march your own army out to destroy the enemy lord.

In skirmish, players report the AI sends waves that get bigger over time, and in the 1v1 demo you always seem to face The Snake, while the 1v3 deathmatch pits you against Penryn, The Snake and Sir Longarm together, according to Firefly's own announcement and a player video on the demo.

Army composition

The official Steam page states that enhanced medieval war mechanics force you to consider weather and army composition — a single repeated unit no longer carries a battle. Units seen working in the demo include:

Two player-verified details matter a lot. First, archers are far more accurate and efficient than in the older Stronghold games — one playthrough notes they "melt normal troops" — so ranged units on high ground are your backbone. Second, the demo's AI lord (The Snake) slaughters infantry sent at him alone; only Captains and swordsmen killed him quickly in that player's test. Keep melee behind your archers, and don't waste cheap troops on hero units.

Honour gates your army

High-tier troops cost Honour as well as weapons and gold. Players testing the demo report you need roughly a thousand Honour to reach the rank that unlocks The Captain, and the practical route is banquets — honey, wine, and other luxury goods. Because production chains are slow and the food economy feels unbalanced in the demo, many players end up buying banquet goods at the market. Plan your luxury production (beekeepers, vineyards, breweries) early, or you will have walls but no elite troops to hold them.

Building a layered defense

Static walls alone fail. The demo playthroughs show a working layered defense:

1. Wall the approach and pick a big gate

   Place your largest gate on the main enemy path and connect standard walls around it. Stone walls need stone stairs — you cannot put wooden stairs on stone walls, and archers cannot reach wall tops without stairs.

2. Dig moats in front of the walls

   Moats are a confirmed returning defensive tool and were added to the October demo. They slow melee units and siege equipment, buying time for your ranged units.

3. Build towers and mount ballistas

   Square, round, octagon and horseshoe towers unlock as you rank up. Ballista towers on top give heavy ranged support. Players report towers have more range than fighting from the wall itself.

4. Add traps, braziers and oil pots

   Set spike traps in choke points, place braziers so you can set areas on fire, and drop oil pots for the big final wave — one playthrough credits oil pots and traps with breaking the main enemy assault.

5. Garrison the high ground

   Longbowmen on towers, archers on walls, men-at-arms at the gate. Repair wall damage between waves — after a heavy attack you will need significant repairs.

One player finished the entire demo campaign defense with nothing but this tower-and-trap layout, calling it "already enough to defend it, even the last attack."

Attacking: siege weapons

On offense, the demo's mechanics work like this:

• Trebuchets must be unpacked and cannot turn on the spot once placed, so position them facing the target wall before unpacking. They demolish walls from range.
• Catapults can turn on the spot and are more forgiving, though they must be built back from the front line.
• Engineers are needed to build artillery; one player recruited ten for a single push.
• Pathing through enemy gates is slow, so an attack-move with a mixed force — Captains and swordsmen leading — clears the enemy lord far faster than infantry alone.

Weather and terrain

The official Steam page confirms the elements are combat factors, not decoration: heavy rain reduces archery range, and snow hinders crop growth. In practice that means an archer-heavy defense is weaker in a downpour, and a long siege in winter strains your food economy — so secure granaries and food production before committing to either. Note that a weather forecast feature, and effects like fog or wind accuracy, have only been described by the rival fan site stronghold4.wiki, not confirmed by Firefly, so treat those as unverified.

What is still unconfirmed

Balance numbers, exact unit costs and the final unit roster can all change between the demo and the December 7, 2026 early access launch. Several demo players, including the YouTuber who recorded a full 1v1 skirmish, report the food and Honour economies feel unbalanced and expect patches before release. Practice in the free skirmish demo on the Steam store page, since it is currently the most reliable way to test the combat system yourself.

FAQ

How does the Stronghold 4 combat system differ from older games?

It keeps the classic siege formula but adds the Honour system gating elite troops, weather that directly affects archery range, larger maps, and more accurate archers. Several players on the Steam community hub feel the moment-to-moment combat is close to the older titles, with the new systems layered on top.

Can archers climb walls and towers on their own?

No. In the demo, archers cannot enter gatehouses like in older Stronghold games — you must build stairs, and stone stairs only go on stone walls. A player learned this the hard way when his archers stood stranded below the battlements.

Are moats and tunnelers still in Stronghold 4?

Yes. Firefly's official Steam page lists moats and tunnelers among the returning classic siegecraft features, and moats were added to the October demo, where players report the AI digs them against you as well.

How do I fight The Snake in the demo skirmish?

Players report he cuts down unsupported infantry quickly. Build a food-secure economy, rank up through Honour, then attack with Captains and swordsmen supported by longbowmen — that combination killed him far faster than mixed melee waves in one recorded run.
