Build a Medieval Army Castle Update Guide

The Castle Update is a major content wave for Build a Medieval Army (Medieval War Tycoon by ZedCo) that introduces new base layouts, revives the Old Castle option, and reshapes how commanders think about defense and layout positioning. This guide covers everything confirmed about the update, how to unlock the Old Castle, what the new castle system means for your army composition, and strategic tips for using the new layouts effectively.

What is the Castle Update

ZedCo announced a Castle Update for 2026 as the next major content addition to Medieval War Tycoon. This update builds on the August 2026 patch that returned the Old Castle to the unlock rotation. The Castle Update expands base customization options, giving players more control over how their medieval fortress is arranged and how that layout affects defensive capabilities and income generation.

The Old Castle, which originally launched with the game in 2017 and was temporarily removed from rotation, returned in the August 25, 2026 patch. This legacy layout offers a different defensive profile compared to the modern castle, giving players who prefer the classic experience a way to return to their preferred playstyle.

Old Castle: What We Know

The Old Castle is the original base layout from when Medieval War Tycoon first launched in June 2017. It was removed from the unlock rotation at some point but returned in the August 2026 update, giving players access to both classic and modern castle designs.

How to access the Old Castle:

1. Navigate to your base settings or layout selection menu
2. Look for the castle variant options
3. Select “Old Castle” from the available layouts
4. Confirm your selection — the layout will apply to your current session

The Old Castle offers a different spatial layout compared to the newer default castle. This affects choke points, defensive positioning, and how your troops can cover different angles of approach. Players who mastered the original layout during the game’s early years often cite muscle memory and established defensive strategies as reasons to prefer the Old Castle.

New Castle Layouts in the 2026 Update

The Castle Update introduces fresh base design options beyond the Old Castle return. While ZedCo has not released every detail publicly, the update aims to give commanders more strategic choice in how their fortress is organized.

Expected features of new castle layouts:

• Different choke point configurations that change how defensive troops are positioned
• Modified income structure placement affecting cash flow optimization
• New visual themes matching the medieval aesthetic
• Alternative patrol routes that interact with the August 2026 patrol command system

Strategic Implications for Army Composition

The castle layout you choose affects which defensive strategies work best. The Old Castle and new layouts each create different engagement windows for attackers and defenders.

Old Castle characteristics:

• Established choke point positions known by veteran players
• Defensive angles that favor high-ground troop placement
• Layout patterns that match older YouTube guides and tutorial content
• Familiar flow for players who started before 2020

New castle layouts:

• Potentially tighter corridors that benefit area-of-effect units
• Modified flag approach routes that may favor aggressive escorts
• Different income building placement affecting reconstruction speed after wipes
• Fresh tactical variables that disrupt established meta strategies

How the Castle Update Affects Prestige Planning

If you are approaching a prestige reset, consider how castle layouts interact with your preferred unit composition. The Income Prestige Planner does not account for castle-specific advantages, so factor in layout preferences alongside the multiplier math.

When to stick with your current castle:

• Your defensive strategy is working and income is stable
• You have mastered the choke points of your current layout
• Unit composition synergies are already tuned to current angles

When to experiment with the Old Castle or new layouts:

• After a prestige reset when you are rebuilding from scratch
• If your current layout feels predictable against skilled attackers
• When new patrol mechanics from August 2026 interact poorly with your existing angles

Combining Castle Choice with Patrol Mechanics

The August 2026 update introduced patrol commands and direct middle flag targeting. These mechanics interact with castle layouts differently depending on which design you use.

The patrol system lets you set automated lane presence for your troops. In the Old Castle, established patrol routes may conflict with or complement new automated commands differently than in modern layouts. Test both approaches:

1. Set patrol commands with your current castle
2. Switch to Old Castle or new layout
3. Compare how troops respond to automated lane assignments
4. Adjust composition based on which layout your patrol system covers better

Defense Tips for Each Castle Type

Old Castle defense approach:

• Leverage well-documented choke points that veteran players recognize
• Position anchor units at proven high-value defensive positions
• Use the layout familiarity to predict attacker paths
• Stack defensive passes like Heal Spell and Cloned Troops at known engagement zones

Modern/new castle defense approach:

• Experiment with area-of-effect units in tighter corridors
• Use the new layout uncertainty to catch attackers off guard
• Position versatile units that can shift between lanes quickly
• Monitor how flag carriers approach and adjust defensive focus accordingly

Comparing Castle Options with the Tier Lists

Castle layouts change how certain units perform. Use the Troops Tier List to identify units whose effectiveness varies most by layout:

• High-mobility pressure units that benefit from open approaches
• Anchor units that excel at specific choke point positions
• Area-of-effect soldiers whose value changes in corridor-heavy versus open layouts

The Gamepasses Tier List helps you decide which purchases make sense given your chosen castle. Some gamepass soldiers may perform differently depending on whether you run Old Castle or modern layouts.

Rebuilding After a Wipe in Any Castle

Each castle layout has different reconstruction priorities after an enemy raid wipes your defensive line. General principles that apply regardless of which castle you use:

1. Restore income structures first to rebuild cash flow
2. Recruit defensive anchors to stabilize the perimeter
3. Add volume units to contest flag approach routes
4. Re-establish patrol automation with the August 2026 command system
5. Push for hill control to accelerate reconstruction through the +20% income bonus
