The Science fiction real-time strategic Game Sins of a Solar Empire was created by Ironclad Games in 2008 and released by Stardock Entertainment for Microsoft Windows. Its creators refer to it as "RT4X," a real-time strategy (RTS) Game that borrows certain features from 4X games. The Game's goal is for gamers to take leadership of a space-faring kingdom in the far future and conquer star systems through military, financial, and diplomatic methods.

On February 4, 2008, the Game was published, and the gaming press immediately gave it favourable reviews and several accolades. On February 25, 2009, its first material expansion was dubbed Entrenchment, and on February 9, 2010, its next material expansion, titled Diplomacy, was made available for download. At that time, a bundle called Sins of a Solar Empire: Trinity was launched, including the base Game and the first two expansions. In June 2012, a third expansion—the standalone Rebellion—was made available. On September 16, 2022, Sins of a Solar Empire II, the Game's sequel, was announced.

This version of Sins of a Solar Empire: New Frontier Package comes with the following:

• Base Game
• Forbidden Worlds DLC
• Official Game Soundtrack

Sins of a Solar Empire: New Frontier Edition's most prominent three features

• Choose between playing as a Loyalist or a Rebel; each opens up new technology, ships, and playing styles for each race.
• Choose from various winning strategies, such as military, diplomatic, research, last capital standing, last flagship standing, and occupation.
• New Corvette Class Boats: Each party has created a new light assault vessel to harass opposing troops that are small and handy.

Key Highlights:

• Rebellion is one of the Solar Empire's sins. The Upcoming Episode of the Award-Winning RTS.
• A splintering of the engaged organisations has occurred despite widespread optimism that Diplomacy would finally end the conflict. This is because of divergent views on what should be done and diminishing the factions in charge.
• To survive the remainder of the conflict, the Trader Emergency Coalition's faithful members adopt an isolationist strategy and concentrate on fortifying their fortifications. The coalition's opponents adopt a fully militant stance, believing that the only way to bring peace is by finally demolishing everyone who stands in their path, especially Xenos.
• The battle causes a rift in the Advent Unity for the 1st time. The loyalists want to pursue their retaliation against the merchants and subjugate everyone else to the Unity's power. Others in the Advent, however, believe that the Unity has been misdirected off its intended course by internal corrupting control.
• Choose between the Unionist or Rebel factions when playing to gain new technology and ships, and enjoy the styles of every race.
• Mighty titans enter the battle to swing the balance of power in the new Titan Class Warships. Each faction has the option of fielding a unique titan with its own set of tactical advantages.
• Additional and Modified Capital Ships: A new capital ship is added to the fleet for each race to provide more tactical choices. Moreover, all significant ships already in use have had their powers improved to four levels, enabling players to concentrate their ships on certain advantages.
• Modern Corvette Class Ships: Each party has created a new light assault vessel to harass opposing troops that is small and handy.
• Graphical Upgrades: The Sins world now looks better than ever, thanks to updates to the visuals, particle effects, lighting, and shadows, as well as the race-specific user interface.
• Make use of several pathways to success, such as military, diplomatic, research, last capital standing, last flagship standing, and occupation.
• Enhanced Audio: Countless new soundtracks, more than 60 minutes of creative music, and dozens of new voiceovers all contribute to the drama of combat being more immersive than ever.
• Tutorials: For new and veteran players, fresh and updated training makes it simple to start creating their own solar empire immediately.
