- Cannon build means centering your castle on protected ranged damage that wins long fights.
- Frontline first: durable units and defensive structures absorb pressure while cannons fire.
- Economy foundation: stable resource generation funds unit unlocks and upgrades.
- Grid discipline: reserve open space for merging and later upgrades before filling every tile.
- Early Access warning: Gridlords balance can change with patches, so retest after each update.
What Is a Cannon Build in Gridlords?
A cannon build is a ranged damage castle strategy in Gridlords. Instead of spreading upgrades across every available unit, you commit to a compact package: a dependable frontline, a concentrated ranged damage core, and utility units that keep the damage layer alive. Because Gridlords battles are automated and asynchronous, your layout must win without direct control, which makes protected damage positions the heart of this plan.
Gridlords is a fantasy pixel-art, asynchronous PvP castle autobattler by Sphere Studios and Goblinz Publishing, available on Steam Early Access since October 7, 2026. The core loop is simple: build a grid-based castle, unlock units, then attack and defend against other players' castles in automated battles.

The cannon build matches what the community calls a "defensive scaling" or "hero-centered" identity: you accept a slower start in exchange for a castle that becomes very difficult to break once the damage layer is established.
Pick one win condition before placing a single tile. For a cannon build, that condition is: "my ranged core outlasts the enemy frontline." Every building, unit, and item choice should reinforce it.
Core Components of the Cannon Build
Every cannon build in Gridlords shares the same structural roles. The table below breaks down each layer and what it contributes to the automated battle.
| Layer | Role | Placement Priority | Upgrade Focus |
|---|---|---|---|
| Economy buildings | Fund unit unlocks and upgrades | Inner grid, fully protected | Generation rate and efficiency |
| Unit production | Unlock the frontline plus damage package | Near the defended core | Access to your main unit package |
| Frontline units | Absorb opening enemy pressure | First contact row | Durability and reinforcement |
| Ranged damage core | Your "cannons," winning long fights | Behind frontline, protected sides | Damage, range, targeting |
| Defensive structures | Shield economy and damage layers | Around high-value buildings | Coverage reliability |
| Utility units | Control, sustain, or amplification | Inner grid, flexible slots | Effect consistency |
Three principles govern how these pieces fit together:
- Do not expose damage on the corners. Fragile damage dealers with high attack values still die first if they take the opening hit.
- Concentrate defense on what matters. Protect the economy and damage core rather than spreading coverage evenly across low-value tiles.
- Reserve grid space. Structure merging and future upgrades become impossible if you fill every slot early.
New players often place their strongest ranged units on the front line because of their high attack values. In automated battles, frontline survivability matters more than raw damage at first contact.
Step-by-Step Cannon Build Setup
Follow this sequence for your first several matches. Each step builds on the previous one, and the order matters.
Choose a defensive-scaling hero
Select a hero that improves consistency, survivability, or the effectiveness of a developed castle. Avoid heroes that demand extreme layouts before you understand the game loop.
Establish the economy foundation
Place your first economy structure early and keep it protected. A cannon build scales slowly, so reliable resource generation is non-negotiable.
Add one production path
Unlock a small unit package: one durable frontline option, one concentrated damage option, and one utility option. Do not unlock more units than your economy supports.
Layer defense around the core
Place defensive structures to shield economy and production first. Add coverage before committing to greedier development steps.
Upgrade the failure point
After each async PvP battle, identify what failed first. If the frontline collapses instantly, improve durability. If enemies reach your cannons while the frontline stands, improve damage and range.
After a loss, adjust a single priority, whether economy, placement, or unit composition. Reworking the whole castle after one defeat hides the actual problem.
Cannon Build Variants
CardGrid helps compare the three practical ways to run a cannon-focused castle. Each variant suits a different opponent pool and comfort level.
Fortress Cannon
- Full defensive scaling
- Layered defense, slow economy growth
- Strongest late-game damage layer
- Weak to early pressure windows
Balanced Cannon
- Compact core plus adaptation
- One production path, moderate defense
- Forgiving for newer players
- Weaker than specialists at their peak timing
Hero-Centered Cannon
- Castle built around one hero
- Units amplify the hero's strongest role
- Powerful coordinated interactions
- Vulnerable if supporting buildings are delayed
| Variant | Best Against | Weakest Against | Difficulty |
|---|---|---|---|
| Fortress Cannon | Aggressive pressure builds | Fast economy snowballs | ★★★ |
| Balanced Cannon | Unknown opponents | Specialized counters | ★★ |
| Hero-Centered Cannon | Static defensive layouts | Hero-targeting counters | ★★★★ |
Aggressive and defensive openings can swing sharply in value when unit costs, production speed, or building durability are rebalanced. Check the Steam community discussions for the latest patch notes before committing resources.
Merging, Space Planning, and Checklist
Structure merging is how a cannon build turns a crowded grid into an efficient fortress. Merge permanent structures only after you understand which buildings are core to the plan and which are temporary stepping stones. Premature merging removes flexibility and can open gaps in your defensive coverage.
A practical merge evaluation:
| Situation | Merge? | Reason |
|---|---|---|
| Repeated low-level economy structures | Yes | Frees space, strengthens resource output |
| Core production buildings, plan unclear | Wait | Merging locks your unit path early |
| Defensive structures creating a coverage gap | No | A gap invites attacks on the damage core |
| Progression building, immediate benefit | Yes | Gains now outweigh lost flexibility |
Cannon Build Milestones:
- Economy foundation established and protected
- Frontline unit package unlocked and upgraded
- Concentrated ranged damage core in protected positions
- Defense layered around economy and production
- Merging planned around the final castle layout
- Failure point identified and upgraded after each battle
Open grid tiles are as valuable as buildings. Reserve flexible space near your core so upgrades, merging, and adaptation stay possible as the match develops.
FAQ
Q: Is the cannon build good for beginners in Gridlords?
The balanced cannon variant is one of the most forgiving openings. It uses a compact economy, one reliable production path, and enough defense to protect the core, which makes it easier to learn the automated battle system without overcommitting to a specialized layout.
Q: How do I counter an aggressive player with a cannon build?
Introduce defensive capacity before making major economic commitments. Layer protection around the economy and production core, and use items that improve resilience so your damage layer survives the early pressure window where cannon builds are weakest.
Q: Should I merge buildings in a cannon build?
Merge selectively. Consolidating repeated economy structures improves space efficiency, but merging production or progression buildings before your plan is established can lock you into a weak unit path or create gaps in defensive coverage.
Q: Will balance changes break this build?
Gridlords is in Steam Early Access, so unit costs, building durability, and hero values can change with updates. Retest your composition after each patch, and prioritize flexible layouts and upgrades that remain useful across balance changes.
