Mods are the highest-impact personalization layer in Birds of War, and a player who learns to subscribe to Steam Workshop, install custom bird skins, custom maps, balance mods, and audio mods can tailor the game to their preferred playstyle. HexNest Games shipped a no-code UE 5.6 mod kit (156 KB ZIP) and integrated Steam Workshop publish-as-of patch 1.1.5, which means the entire player-side flow — discover, subscribe, install, manage — is doable from inside Steam without writing a single line of code. This guide walks through the player-side mod workflow: discovering mods on Steam Workshop, subscribing to mods, the mod loadout manager, the per-mod-type install quirks, the ranked-play restrictions on mods, and the discipline that separates a clean mod loadout from a broken one.
Discovering Mods on Steam Workshop
Steam Workshop is the central mod discovery hub for Birds of War. The Workshop page is integrated with the Steam store page for the game.
Step 1 — Open the Workshop
The Steam Workshop for Birds of War is at steamcommunity.com/app/4223300. The Workshop tab shows all published mods, sorted by:
- Most popular (subscribers)
- Most recent (publish date)
- Most trending (recent subscriber growth)
Step 2 — Browse by Category
The Workshop supports five mod categories, each with its own filter:
| Category | What it ships | Typical use |
|---|---|---|
| Custom Bird Skins | New visual skins for the seven launch birds | Cosmetic personalization |
| Custom Maps | New playable maps beyond the five launch maps | Map variety |
| Balance Mods | Numerical tweaks to bird abilities | Custom meta |
| Audio Mods | Replacement sound effects or music | Audio personalization |
| Total Conversion | Full game replacements (rare) | Complete overhauls |
Step 3 — Read the Mod Description
Each mod page has a description, a preview image, and a comments section. The description should specify:
- Compatibility: which patch version the mod targets (1.0.5 / 1.1.0 / 1.1.5)
- Required dependencies: which other mods are required
- Conflicts: which mods are incompatible
- Author notes: installation quirks
Skipping the description is the most common mod install mistake. A mod that targets 1.0.5 will not work on 1.1.5, and subscribing to it creates a broken mod state.
Subscribing to Mods
Subscribing to a mod is the install trigger. Steam handles the download, the placement in the mod folder, and the in-game enable automatically.
How Subscribe Works
The subscribe flow:
- Player clicks Subscribe on the Workshop mod page
- Steam downloads the mod in the background
- Steam places the mod in the Birds of War mod folder
- Steam notifies the in-game mod manager that the mod is available
- The in-game mod manager enables the mod on next launch
The subscribe-to-install flow is fully automatic after the player clicks Subscribe. No manual file placement is needed.
Subscribe Best Practices
Three subscribe best practices prevent broken mod states:
- Subscribe during the menu, not during a match: subscribing mid-match can crash the game or corrupt the in-game state
- Subscribe one mod at a time when troubleshooting: a multi-mod subscribe can hide which mod is causing a problem
- Re-verify the mod after a game patch: a patch update can invalidate previously-working mods, and the player needs to re-verify after each patch
The In-Game Mod Manager
The in-game mod manager is the player's interface for enabling, disabling, and ordering mods. The manager is accessible from the main menu under Options → Mods.
Mod Manager Layout
The mod manager has three panels:
| Panel | Function |
|---|---|
| Left | Subscribed mods list |
| Center | Mod details (description, version, conflicts) |
| Right | Mod loadout (enabled mods in priority order) |
Enabling and Disabling Mods
Each subscribed mod can be toggled between Enabled and Disabled with a checkbox. Disabled mods remain subscribed but do not load during gameplay. The discipline is to disable mods that are not currently in use, which reduces the risk of conflicts.
Mod Loadout Priority Order
The mod loadout has a priority order that matters for conflict resolution. If two mods modify the same bird skin, the higher-priority mod wins. The priority order is drag-and-drop, and the player can rearrange the order at any time.
The recommended priority order:
- Total conversion mods at the top (they replace everything)
- Custom maps below total conversions
- Balance mods below custom maps
- Custom bird skins below balance mods
- Audio mods at the bottom
Per-Mod-Type Install Quirks
Each mod type has specific install quirks that the player should know before subscribing.
Custom Bird Skin Mods
Custom bird skin mods are the most common Workshop content. The install quirks:
- Texture resolution: the recommended texture resolution is 1024x1024 for the bird body and 512x512 for the wing. Lower resolutions look pixelated; higher resolutions cost performance.
- Tint compatibility: some skins include custom tints that may conflict with the in-game tint controls. Disable the in-game tint for affected birds.
- Bird-specific: each skin targets one of the seven launch birds. Subscribing to a Crow skin does not enable it on the Eagle.
Custom Map Mods
Custom map mods replace or add new playable maps. The install quirks:
- Map size cap: custom maps are capped at the prefab-shipping size budget. Very large maps (Coliseum-tier) may fail to load.
- Egg spawn placement: custom maps may have different Egg spawn densities than the launch maps. Read the mod description for the spawn distribution.
- Updraft placement: custom maps may have different updraft counts than the launch maps. Read the mod description for the updraft layout.
Balance Mods
Balance mods tweak numerical values for bird abilities. The install quirks:
- Patch compatibility: balance mods are patch-version-specific. A mod targeting 1.1.0 will not work on 1.1.5.
- Comp math impact: balance mods change the comp meta significantly. Read the mod description for the recommended comps.
- Ranked restrictions: balance mods are NOT allowed in ranked play (see "Ranked Restrictions" below).
Audio Mods
Audio mods replace or layer sound effects and music. The install quirks:
- Voice chat interaction: audio mods that replace proximity voice chat sound effects may interfere with the positional audio. Test in unranked before using in competitive play.
- Music layering: some audio mods layer music on top of the default soundtrack. Layering can cause audio clipping if the mod is not balanced.
Ranked Play Restrictions on Mods
Ranked play has strict mod restrictions. A player who queues into ranked with a banned mod will be kicked from the queue.
| Mod type | Ranked allowed | Reason |
|---|---|---|
| Custom bird skins | Yes | Cosmetic only, no gameplay impact |
| Custom maps | Yes (some) | Some custom maps are whitelisted by HexNest |
| Balance mods | No | Changes comp meta |
| Audio mods | Yes | No gameplay impact |
| Total conversion mods | No | Replaces the game |
The balance mod restriction is the most important because balance mods are the only mod type that changes gameplay. A balance mod that buffs Seagull Chip Frenzy would be unbannable, but the ranked mode enforces the ban to protect competitive integrity.
Whitelisted Custom Maps
HexNest maintains a whitelist of custom maps that are allowed in ranked. The whitelist is published in the HexNest Discord and updated with each patch. Players who want to play custom maps in ranked should check the whitelist first.
Managing Your Mod Loadout for Ranked
A clean mod loadout is essential for ranked play. The discipline is to maintain two loadouts:
Loadout 1 — Ranked Loadout (Minimal)
The ranked loadout includes only mods that are allowed in ranked:
- Custom bird skins (cosmetic only)
- Whitelisted custom maps
- Audio mods (no gameplay impact)
The ranked loadout should be tested in unranked before queuing into ranked.
Loadout 2 — Casual Loadout (Full)
The casual loadout includes all subscribed mods, including balance mods and total conversions. The casual loadout is for unranked play, training, and mod exploration.
Loadout Switching Discipline
Three loadout-switching disciplines prevent ranked mistakes:
- Switch to ranked loadout before queuing ranked: the discipline is to verify the loadout is clean before queuing
- Verify loadout after each patch: a patch update can reset the loadout state
- Test new mods in unranked first: never queue a new mod into ranked without testing it first
Troubleshooting Common Mod Issues
Three mod issues appear repeatedly in player reports:
Issue 1 — Mod Not Loading
A mod that subscribed successfully but does not load in-game is usually a patch-version mismatch. The fix is to check the mod description for compatibility, then either downgrade the game or wait for the mod author to update.
Issue 2 — Mod Conflict
Two mods that modify the same bird or ability create a conflict. The conflict shows up as one mod "winning" over the other, or as a crash on load. The fix is to disable one of the conflicting mods.
Issue 3 — Mod Crashes the Game
A mod that crashes the game on launch is usually a total conversion or a mod with missing dependencies. The fix is to disable the mod in the mod manager, verify the dependencies, and re-enable the mod.
Mod Etiquette and Community Standards
The mod community has unwritten standards of etiquette:
- Credit the original artist if the mod reuses assets from another mod
- Specify the patch version in the mod description
- List conflicts explicitly in the mod description
- Engage with comments from subscribers to maintain quality
- Update mods after patches to maintain compatibility
A mod author who follows these standards builds a subscriber base faster than a mod author who skips them.
