What is Sins of a Solar Empire?

Sins of a Solar Empire II is a real-time strategy game with many traditional 4X elements (Explore, Expand, Exploit, Exterminate). You take the role of leader of one of the game’s factions in order to build a stellar empire using force, trade, alliances, subterfuge and more.

What are the core features of a Sins of a Solar Empire game?

Starting on your homeworld, you begin by exploring your local system. Each area in the game is pre-populated, however, so to expand you will need to use force of arms. To do this, you’ll construct capital ships, cruisers, frigates and strike craft to take over the planets around you. With each world, you can increase your empire’s capabilities and specialize your planets. You’ll also build research stations to learn new technologies and to unlock new ships. Eventually you’ll encounter another major player and it’s at this juncture you must decide if you want to try and be friends or not.

What is the current state of the game?

Very similar to the state we began the original Sins of a Solar Empire ‘early access’ program in. At present, most of the gameplay systems are implemented. We are making steady progress on the visual content and overall UI/UX, representing roughly 1/4 of the content overall. We’re still working on many models, particle effects, damage effects and debris, user interface art, music, voice work, sound fx, and more.

Why do I see some old models and effects?

We use these as placeholders so we can verify the underlying game system is working as intended while we wait for the new assets to be created.

What will change from Early Access to final release?

From the initial Technical Preview we plan to add the various factions, single-player and multiplayer gameplay, more art, sound, music, and a whole lot more.

What is the setting for Sins of a Solar Empire II?

Sins of a Solar Empire II is set in another galaxy where three major races vie for survival in an unending war. Although the story begins 10,000 years in the past, the game picks up at a point where the TEC, Vasari and Advent are all locked in a deadly conflict for supremacy.

All three major races (TEC, Advent and Vasari) will be playable at final release; players can choose to be part of either their loyalist or rebel faction.

What is new in Sins of a Solar Empire II?
Will you support multiplayer?

Absolutely! Much like the original Sins of a Solar Empire, we host our own multiplayer servers. This way, you can play with others no matter where you got the game.

Will you support mods?

Mods are a big part of why Sins of a Solar Empire continues to be enjoyed and played by so many. Sins of a Solar Empire II will provide an improved system to allow mods to be created, shared and downloaded from within the game and hosted on Stardock's Tachyon servers. So that all mod content is available regardless of where it was created or where you are playing.

How are the maps different?

The biggest initial change is that planets will now orbit their parent star (as a gameplay option). Over time, this changes the way the phase lines connect which can have some pretty interesting consequences!

What is new with technology research?

There have been many improvements to the technology system in the game. The most immediate is that there is only one research station now, instead of the separate Military and Civilian structures from the original Sins. Each race/faction (loyalist/rebel) now have more unique technologies that make them stand apart as compared to Sins 1. Additionally, some high-tier research subjects require special resources to complete.

How have combat and war changed?

The combat system has been improved significantly in Sins of a Solar Empire II. For starters, many units now have true, turreted weapons that individually track targets. Additionally, there are now true point-defense weapons in the game to shoot down enemy missiles and strikecraft. One of the coolest things we’ve tried is to fire off a swarm of missiles at an enemy, then move one of our capital ships in to take the hit instead. The game’s armor and shield mitigation systems have also gotten updated.

What other changes are coming?

Far more than I can put in this limited space! Stay tuned to our website for more information as we progress through Early Access.
