This update not only enhances the gameplay experience but also introduces a plethora of new features that will excite both veterans and newcomers alike. From Steam achievements to significant improvements for the Advent Unity abilities, this update is a game-changer.

Steam and Epic Achievements:One of the most exciting additions in the Unity Ascendant Update is the introduction of Steam and Epic achievements. Players can now showcase their prowess and dedication to the game with a variety of challenges. Here are just a few examples:

  • Talk Like A Pirate: Max out your reputation level with Pirates.
  • Who's Stopping Us?: Get a Titan to level 10.
  • Dust and Echoes: Strip to the Core 30 planets in one game as Vasari Exodus.
  • Go Big or Go Home: Win a match using only capital ships.

New Gravity Wells:The update also introduces two new gravity wells that promise to enrich the exploration aspect of the game. These new locations will not only enhance the lore of the game but also provide new strategic opportunities for players:

  • Ship Graveyard: A colonizable gravity well filled with the debris from a long-forgotten battle, ripe for the taking.
  • Space Junk: A non-colonizable gravity well, also filled with remnants of past conflicts, providing a unique backdrop for your interstellar adventures.

Advent Unity Ability Improvements:Faction ThemesThis update emphasizes the contrasting approaches to warfare taken by the Wrath and Reborn factions. The Wrath Advent faction embodies a classic archetype centered on Control, Culture Spread, and Vengeance. They excel at debuffing enemies and spreading culture, leveraging aggressive mechanics to dominate their foes without concern for the cost.

In contrast, the Reborn Advent faction adopts a more radical stance, focusing on Restoration and Sacrifice. They draw power from the loss of their own units, intentionally sacrificing ships to fuel their abilities while effectively countering enemy aggression.

New Abilities BreakdownThe update introduces five new Unity abilities, with Wrath gaining three and Reborn acquiring two.

  • Wrath Abilities:
    • Avatar: A potent fleet buff that significantly boosts damage output.Chastise: A control ability that restricts enemy movement, preventing escapes.
    • Fury: A direct damage ability that unleashes raw power on foes.Wrath also retains Clairvoyance for enhanced map awareness and Proselytize, which has regained its unrestricted culture projection capabilities.
  • Reborn Abilities:
    • Cleanse: A sacrificial ability that heals nearby units by destroying one of your own.
    • Resurrection: A game-changing ability that allows players to restore entire fleets mid-battle.The Reborn faction shares Clairvoyance and retains Recall and Sanctify, further enhancing their strategic options.

Focus Economy OverhaulA significant overhaul of the Focus economy accompanies these updates. Focus capacity is now front-loaded and harder to increase, while regeneration is slower. This change encourages players to manage their resources strategically, allowing for bursts of Unity power at a cost. Adjustments to ability costs and cooldowns create a more dynamic system that rewards careful planning.

Improved Research OptionsNew faction-specific research options have been added, such as Rite of Reclamation for the Reborn, which accelerates wreck salvaging, and Clarity of Purpose for the Wrath, enhancing Psi Power within their culture. The research trees have been refined for better readability and accessibility, with notable buffs to existing technologies.

The Future of ConversionWhile Conversion is a key aspect of the Wrath faction, its current implementation has been problematic for balanced gameplay. It has been temporarily removed and will return with a more nuanced design in a future update, ensuring a fairer competitive landscape.

Advent Ascendent Updates

A key part of this update is to emphasize the different themes and approaches to warfare preferred by the two factions. For now, these differences manifest most strongly in their use of Unity abilities, but these themes are at the core of the factions as a whole and may appear again in other ways in future updates. So, what are they?

The Advent Wrath faction is the more archetypal of the two factions. They are focused on Control, Culture Spread and Vengeance. They express the Control theme with mechanics like Mind Control and a greater focus on debuffing the enemy. Culture is important for both Advent factions, but the Wrath have an easier time spreading it and gain more strategic potency from doing so. Vengeance is expressed with the faction’s greater focus on aggressive mechanics like damage and offensive self-buffs, as they seek to destroy their enemy without heed of the cost.

Meanwhile, the Reborn Advent faction is a bit more extreme in some of its themes. They are focused on purifying the Unity, leading to the themes of Restoration and Sacrifice. They draw power from the deaths of their own units and even have cause to intentionally destroy their own ships. Yet at the same time they seek to prevent outside interference, and with their restorative powers they can prevent enemy aggression quite effectively.

Unity Ability Changes

This update brings five new Unity abilities between the two Advent sub-factions. Reborn gain two new abilities, while the Wrath gain three. The existing abilities have been split between the two factions.

Wrath gains:

  • Avatar: A potent buff for your fleet that can greatly improve damage output.

  • Chastise: Punishing movement control to prevent enemy aggression – or escape.

  • Fury: To deal raw damage directly to the enemy.

Wrath keeps:

  • Clairvoyance: For unparalleled map awareness.

  • Proselytize: Once again unshackled from restrictions, it regains its map-wide culture projection power.

With these five powers, the Wrath faction has a lot of power and aggression available – but also a lot of synergy. Will you Chastise the enemy to prevent them escaping from the area effect of Fury? Will you combine Fury with the Rapture Battlecruiser’s level 6 ability Malice? Which capital ships will you empower with Avatar – or will the Coronata Titan be the sole recipient of this significant power boost?

Reborn gains:

  • Cleanse: To sacrifice a ship of their own to heal those nearby.

  • Resurrection: To restore entire fleets remotely – even mid battle.

Reborn keeps:

  • Clairvoyance: For unparalleled map awareness – the one shared ability.

  • Recall: To save a fleet from certain destruction or roam far afield without consequence.

  • Sanctify: Which can save a planet from enemy attack… For a while.

The new Reborn powers enable their sacrificial mechanics, while further enhancing their strategic capacity. No force of frigates, cruisers, or corvettes is ever truly lost to them when they can resurrect and recall them. They can freely sacrifice their own units to keep important capital ships alive – or fuel the Eradica Titan – knowing that those units can be restored with relative ease. Even if they find themselves at a disadvantage, they can always Sanctify a planet to blunt an enemy assault and buy time.

Focus Economy Improvement

Critical to improving Unity gameplay is the accompanying overhaul of the Focus economy. Focus capacity is now front-loaded, while being harder to increase than before. Focus regen is low, however, and this stat is the main one you will be trying to improve if you wish to make heavy use of Unity in a match. Focus costs and cooldown times on abilities have been adjusted to make better use of this paradigm.

The result is a system that is more dynamic and allows different unlock orders. It also enables more use of Unity powers in short bursts, but with an appropriately significant cost in time should you manage to deplete your Focus pool. Overall, this resource is now managed on a more strategic timescale compared to before.See AlsoSins of a Solar Empire 2 reviewSins of a Solar Empire II PCSins of a Solar Empire 2 Review - IGNSins of a Solar Empire II Windows game

Research Improvements

Some new faction-unique research subjects have been added to the factions, notably:

  • Rite of Reclamation: A Reborn tech allowing them to greatly increase wreck salvaging time. Just in case they want to Cleanse one of their own capital ships…

  • Clarity of Purpose: A Wrath tech to improve Psi Power within their own culture, giving them a tangible reason to spread – and fight inside of – their culture early in the game.

Numerous research topics have been tweaked in unlock orders and layout to make the Advent Culture and Focus trees more readable and accessible, with a few extra buffs as well. Most notably, the Reborn unique techs Soul Reclamation and Protection of the Unity have both seen significant buffs – with Soul Reclamation a standout in how much it can now fuel the Reborn economy when sacrificial tactics are used.

The Future of ConversionWhile Conversion is a key aspect of the Wrath faction, its current implementation has been problematic for balanced gameplay. It has been temporarily removed and will return with a more nuanced design in a future update, ensuring a fairer competitive landscape.
