Hi, I'm sure this is a real noobie question, but I recently bought Gal Civ II and decided to play through the campaign. I'm on the second mission and started researching space militarization: the game screen says I have three options (lasers,mass weapons and one other), however on the research tree only lasers are listed.I remember seeing the others on the demo,but for the life of me I can't find the other two. Is this a bug or simply the way the campaign is set up? Thanks
