Vasari Rebels: Echoes of the Past Update

Our November 'Echoes of the Past' update brings a number of new player-requested features to try out!

Fleet formation and engagement ranges allow players to fine-tune how their ships behave. Create picket-lines or wide formations to avoid area-of-effect damage. When capital ships and titans are destroyed, they now leave behind wreckage that you can harvest - space recycling at its finest.

We've also added structure repositioning, allowing you to adapt to changing phase lanes by moving structures around planets. Keep in mind that this temporarily disables construction. In addition, players can now enjoy game replays to review and analyze matches.

Gameplay improvements, including better target prioritization, refined unit positioning in formations, and improved unit behavior during combat are also present. See below for more details.


Formation and Unit Controls

Players can now have more precise control over their fleets. You can set engagement ranges for your units, allowing them to hold their position, attack nearby areas, or engage anywhere in a gravity well. Additionally, units added to a fleet will automatically follow the fleet's behavior, ensuring better coordination. Wide or narrow formations for your fleets are also available to improve strategic positioning.

Ship Wreckage

Capital ships and titans, when destroyed, now leave behind valuable wreckage that can be collected for resources. This adds a new layer of resource management to the game, making every battle even more significant.

Orbital Structure Repositioning

You can now reposition orbital structures by setting them to orbit around a planet. This feature is particularly useful for altering phase lanes and adapting to changing game situations.

Game Replays

A long-requested feature, the game replay function has been added. You can load and replay your games directly from the "Watch" window on the main menu. This is a valuable tool for reviewing your past matches and improving your gameplay.

Player Customization Screen

In the latest update, players can now personalize their units with primary and secondary color choices. This allows you to put your unique mark on your in-game forces, making them stand out on the battlefield.

These new features offer a more refined and customizable gameplay experience without overwhelming players with excessive changes. Whether you're a veteran commander or a newcomer to the game, these additions will undoubtedly enrich your gaming sessions. Enjoy exploring the latest update!


Echoes of the Past Full Changelog:

Release Status: *** RELEASED ***

Our November update brings a range of exciting additions and enhancements for Sins of a Solar Empire II. New formation and unit controls give you engagement range options, allowing units in fleets to inherit these ranges automatically. Additionally, you can move units into narrow or wide formations for strategic positioning, while ship wreckage from defeated capital ships and titans can be collected for valuable resources.

Furthermore, the introduction of structure repositioning lets you adapt to changing phase lanes by orbiting structures around planets, albeit at the cost of temporarily disabling construction. The update also includes the addition of game replays, enabling you to review and analyze your matches, and a player customization screen for race-specific color choices.

We’ve also included several gameplay improvements, such as enhanced target prioritization, refined unit positioning in formations, and better behavior for units in combat. This update also addresses balance concerns, including adjustments to the phase resonance points and other in-game elements.

Version 1.17.10 is not save game compatible with prior versions.

  • Fixed flashing minor faction auction button showing up when the auction is not visible due to minor faction not being discovered.

  • Fixed fleet units flying backward when they are already at the destination gravity well of the leader.

  • Fixed fully unbuilt units showing up in the selection window. They should only show up once the unit starts building and exists for other units to interact with.

  • Fixed instant build strikecraft action only building interceptors, not bombers.

  • Fixed insurgent units spawning still spawning for dead players.

  • Fixed issues with dead minor factions:

    • Stopped updating the internal state of minor factions so they won't attempt to auto-cast player abilities, won't update reputation, will cancel all events (pirate raid), and won't update the market.

  • Fixed item owner constraints inverted logic. Was causing bomber armor for Vasari cap ships to not show up in the menu.

  • Fixed rare condition attack_command attempted to be sent with 0 targets causing assert.

  • Fixed split fleet due to stop/hold commands. Remote ships in fleets will now attempt to reform with fleets if they have no more user orders in the gravity well they are in. This way, if the fleet is selected and hold/stop is pressed, the remote ships will not be stranded.

  • Fixed trade port culture spread research doing nothing.

  • Fixed Vasari phase jumping multiple starbases to one gravity well.

  • Fixed missiles being controllable.

  • Made concussion_charge and orbital_cannon_shell not controllable.

  • Fixed fleet tooltip inaccuracies and front-end window visibility at the game's start.

  • Addressed the unit constraint bug making it unusable and adjusted phase resonance upgrade costs.

  • Rectified fleet units' stuck movement issues due to the fleet leader's death during ship building.

User Interface:

  • Added key bindings to the settings screen.

  • Added a planet to the bookmark bar with right-click (instead of having to drag and drop).

  • Added quick buy and sell market actions to the top bar. Hold ALT and left or right-click the metal or crystal values to buy or sell the resource.

  • Added bindable activate_focus_targeting input action. Previously focus targeting (override targeting mode to focus on the target unit) was hardcoded to ALT in code. It is now moved off ALT and is bindable because holding ALT is used other places that need the cursor state to not change.

    • For example, holding ALT to build a structure auto-using the market for resources should change the cursor to build structure when the button is pressed but looked buggy because holding ALT forced the focus cursor to show up. As a bonus, can re-enable the custom focus cursor by default as it was only disabled because ALT was messing up XBoxGameBar screenshots.

  • Fixed issues with auto-using the market (ALT) when building structures.

  • Fixed being able to zoom the camera past the unit's min distance.

  • Added wide move UI to the move button.

  • Changed phase gate indicator icon to be purple.

  • Fixed gaps between background brushes at non-standard DPIs.

  • Improved market post-game stats: Credits, metal, crystal received no longer hidden in credits_given catch all stat.

  • Improved UI around structure slots. Show used/max in the build window and reduce the complexity of the tooltip for building structure.

  • Moved game summary chart tooltip to the right so it doesn't cover up categories.

  • Removed pips from structures that have no fixed limit around the planet. It was a bit too confusing between infinitely buildable structures and finite structures (ex. factories vs. trade ports).

  • Split hotseat setting to distinguish between other human players and AI players. Desirable to be able to change settings for these two different types of players on their own.

  • Split total structures statistic into civilian and military slots used.

  • Swapped escape order between HUD and targeting. Will now escape current targeting mode before advanced popup windows are closed. Felt weird to start placing a structure and escape would close the structures window, not abort placement.

  • Fixed purchase tooltip to handle items with only exotic prices, no assets.

  • Improved Vasari Regeneration Bay buff tooltip.
