This version of Nectaris is an updated and expanded version of the original game with a new background story, an entirely different graphical style and lots of new content. It includes all maps (the setting of which has been changed from the Earth's moon to Triton) and units from the original game. Two new sets of maps (the Romulous and Pacifica campaigns) have been added for a total of 96 levels. There are also many new units, more than doubling the number of the original. The non-lunar settings of the new campaigns allow for naval units for the first time (including submarines and ship-based aircraft), as well as such units as helicopters, jump-jet infantry and paratroopers.
