They have taken many areas to a whole new level than what was in the 80s version. Air combat for one. You actualy have to work at shooting down the UFOs. It's quite awesome and the early demo beta version they threw out there awhile back and tried out. I would "hope" it gets even better than what was in even that version - and am sure it will. I'm not in the Beta or anything but did get a hold of the demo beta they had. Looked very promising.I can PERSONALLY assure you that this Firaxis X-Com sequel is indeed a true successor to the original, having both the tactical, strategy and campaign elements. But with both evolved quite heavily to reduce tediousness in the UI and routine management. Xenonauts is an admirable CLONE but only a clone, as we can still play the original with Dos-Box I don't particularly see what need Xenonauts fills however well made it may be.
