Imply Missions for the Game

What exactly do you mean by mission?

It sounds like he means campaign...

Yep! A Campaign

Every Game has its own missions, unlike this game but I LOVE THIS GAME!!! AHahaha!

But please make some Missions/Campaign for this.

Not happening I'm afraid (people have been asking for it for years). Sins has a subtle story that's up to you to interpret as you fight your battles that are just a small part of the galactic war. We will probably have to wait until Sins 2 for a campaign.

That said, new expansion is supposed to have something called "Scenarios", but at best that sounds like either unique missions with no real story, or just unconnected stories in the Sins universe. At worst, is just some new premade maps like they added in the other expansions.

Hm... If that will not gonna happen then we will not know how did the War begun between the three Factions and how they manage to advance in every technology and researches. Too sad to read it  but anyway I still love this game!  

Sword of the Stars never really had a campaign either (and neither will SOTS2 ). Personally I like.

Some of the story is in the lore section of the website and in the instruction manual, as well as the Vanilla/Diplomacy game intro videos.

In summary though, the war began when the Vasari, fleeing from some unknown force that destroyed their Empire, arrived in TEC space. They were initially unprepared but managed to mobilize their industry to start to beat back the invaders. Then the Advent returned, a group of Humans the TEC encountered a millennium ago but banished them for their cultural practices, which were too bizarre for the somewhat xenophobic TEC to tolerate. Naturally, the Advent did not liked being kicked off their home world, and vowed revenge against those that cast them out. Their timing was all too perfect, now as a three way contest, just who would win the war is anyone's game.

The two expansions don't add all that much too the story, just telling the progression of the war as ultimately all sides start "digging in" for what was clearly going to be a war of attrition, and then attempting to turn to diplomacy to as it became clear that no side had what it took to breach the others defenses alone.  The exact story going into Rebellion is unknown, but it seems after decades of all out war the previously united factions are starting to fall apart, all while the faceless threat that has chased the Vasari for millennia gets ever closer.

Hm... It seems that their will be another faction that will appear in the future.

Possibly.  There's a fairly large group of people (myself included) that are confidant that the ancient enemy is grey goo and someone recently started a mod to attempt to add to the story.  It's pretty interesting if you ask me.

Also, if they have scenarios which have certain objectives, I hope we can mod them.  Because the moment you allow a modder to make something like that is the moment that they overnight make a campaign.  Someone better at modding will see this and it will likely continue up the chain until you have expert modders creating a very realistic and professional looking campaign that portrays the story (and would be considered by most players quasi-cannon).

They haven't said anything about it for Rebellion, but anything after that will most like have one yes.
