Update 0.30.1 — Isometric View, UI Overhaul & Diplomacy Expansion

It’s been a while since our last update on the 15th of February — here’s everything that’s landed since then. The two headliners this time: a brand new isometric camera view, and a big visual overhaul of the core UI (Notifications, Empire view, Settlement view, New Improvement and New Unit screens all got reworked). Alongside that: an expanded diplomacy/treaty system, AI personalities, and a long list of bug fixes and balance tweaks.

Highlights

  • New isometric camera view, with its own rotation controls, compass HUD widget, and tuned zoom/pan behavior.
  • Major UI redesign across Notifications, Empire view, Settlement view, New Improvement and New Unit screens.
  • Diplomacy expanded: treaties now have expiry dates/states, a pending treaties screen, and a new “Surrender and join nation” (ChangeAllegiance) action. Multiplayer can now terminate treaties directly.
  • AI personalities: a new dormant AI personality model now feeds into AI decision-making, and the AI can perform difficulty-gated flanking maneuvers.
  • Undo/Redo in the Map Editor now supports units and rivers, not just tiles.

UI

  • Encyclopedia book icon now lights up on hover; click it to open the Encyclopedia.
  • New season progress bar, with matching Encyclopedia entries for seasons and bad weather.
  • Load Game screen now has a filter-by-name input.
  • Mute button added to tutorial windows (replacing the old click-anywhere-to-mute).
  • Pending treaties screen added to the Diplomacy UI; treaty proposals now have input fields plus Accept/Reject icons.
  • Garrison button added directly on controlled settlement tiles.
  • Added a “quit to desktop” button.
  • Added a confirmation dialog when starting a New Map (Simple/Advanced) so you don’t accidentally lose Map Editor progress.
  • Language selection moved to its own Settings tab.
  • City name now shown in the header of the Build Improvement screen.
  • Fixed several text sizing/margin issues (unit stat text, settlement inspector, objective lines).
  • Fixed the Encyclopedia and Terms of Service being unable to open in certain states.

Gameplay

  • Units now automatically return to the nearest settlement when low on food or HP.
  • Added a tutorial warning when settling with non-Peasant units.
  • Deer now have proper behaviour and animations that react to game speed; geese no longer fly through the sky during season transitions.
  • Boats now float on water instead of clipping into it.
  • Storm cloud particle opacity is now configurable; season-inappropriate weather effects now clear properly on season transitions; added a warning when idling on a tile with an active weather effect.
  • Fixed the NonSettling nation trait incorrectly disabling settling for player nations.
  • Rebalanced cavalry combat calculations and Spearmen vs. Cavalry matchups.

Multiplayer

  • Lobby settings now lock once a player clicks Ready.
  • Added a Defeat screen for multiplayer matches.
  • Fixed AI diplomacy responses not syncing correctly between clients.
  • Fixed traders incorrectly joining armies while trading on a settlement tile.
  • Fixed boarding/disembarking transport ships in multiplayer.

Graphics

  • New isometric camera view.
  • Fixed mountains appearing too dark.
  • Fixed cliffs displaying the wrong texture; added correct seasonal textures for cliffs and mountain connectors.
  • Fixed a grass pixel-fighting/sampling issue.
  • Added an ambient occlusion pass.
  • Fixed a water rendering bug.
  • Fixed bridge models disappearing when a fortification is built on a bridged tile.

Input

  • Expanded gamepad support: right stick can now be used for primary input detection, B button skips campaign cinematics, and the cursor now auto-hides when using gamepad or keyboard.
  • Replaced the game speed number label with a clickable 1–5 speed selector.
  • Added middle-mouse-button panning to the Map Editor.
  • Enabled zoom scrolling in the New Improvement and New Unit screens (Escape to leave them).
  • Camera can now move closer to the ground without clipping through terrain; pan/zoom speed now scales with camera height.

Editor

  • Undo/Redo now supports units and rivers.
  • Drag-to-move for units/armies.
  • New scriptable event actions: ChangeAllegiance, RemoveUnitFromTemplate, StopUnit, StopUnitOnTile, CreateEventLogEntry, SetNationTaxes.
  • Added DuplicateTrigger for quickly copying triggers.
  • Fixed the Reveal Tiles and Highlight Target Tile actions.
  • Mineral placement now defaults to a random mineral type instead of a fixed one.
  • Units can now be marked recruitable/not recruitable per faction directly in the editor.
  • Map Editor save now reuses the existing file path instead of always prompting.

Bug fixes

  • Several crash fixes.
  • Fixed the Recruit button staying greyed out after taking control of a settlement.
  • Fixed the unit inspector/action bar showing the wrong state after loading a save with a unit selected.
  • Fixed broken movement for previously garrisoned units.
  • Fixed embarked units failing to heal while within your own borders.
  • Fixed enemy units becoming invisible when fog of war was disabled.

  • Fixed the ship transport (UnitCargo) panel being hidden behind the HUD.
  • Fixed selection/target markers rendering behind rivers and ocean.

Technical

  • General performance improvements to how the game world looks up units and entities.
  • Additional stability and crash fixes across the board.

Planned development

  • New combat-focused tutorial highlighting flanking, unit advantages, and siege mechanics.
  • More historical campaign scenarios following Caesar’s Gallic campaign.
  • Continue iterating on the isometric view and UI redesign based on feedback.
  • Expand AI personality behaviors further.
  • More diplomacy and treaty options.
