Flagships, Invading planets, and Stacking
Hi there, newbie here with a few questions. I have read the Beginner's Strategy guide and some AARs (with pictures; the one at Galciv2Guide.com is good). However, I can't find anything on the campaigns except the through Wiki site and that only gives the same info that you get in the game. By the way, I'm playing the campaign through the Twilight of the Arnor interface and I'm on the first mission 'An Unexpected Visitor'.
The mission objectives state that we need to take the 3 planets that are controlled by the Drengin and protect the outpost (which I'm assuming is the Altarian outpost mentioned in the mission description. Sounds easy enough but once I get into the mission I realize there's a long way to go to complete it (for a newbie).
I start with a colony ship and a scout ship; no flagship. I start exploring the universe and finding other planets that I can colonize and I do so. I'm researching techs as well. Stuff like New Propulsion Techniques, Ion Drive, Planetary Invasion, and many others. At certain points I see that I can make new ships (like little fighters and stuff) and at some point I was able to build a transport (but I'm not sure what tech unlocked that).
So I created my transport and moved him to the enemy Drengin planet and nothing happened; he wouldn't attack or anything. So then I see that I need a flagship to take down the planetary defenses before the transport can land and invade. That's where my problem lies. How do I create a Flagship? I've figured out how to use the Shipyard and create my own ships but there is nothing about creating a Flagship (at least not yet). There was one tech(I thought it was New Propulsion Techniques) that mentioned that we could now create a Flagship in its description but that it required two other techs; and then it didn't mention what those other techs were!
Main question: How do I create a Flagship and what do I need to put on it to take down planetary defenses?
Second question: Is invading the planets the way to win this particular mission by 'taking the Drengin controlled planets'?
Third question: Sometimes when clicking on a single ship I see something in the information window about 'stacking' and then a number like 3 or 5. What does that mean? I thought I only created a single ship. Did it really create a group of ships?
Thanks for any input. I'm sure stuff like this was answered long ago (or recently) but the Search function on this forum is broke.
