Gamecloud - Will Maelstrom feature upgrable units in the game? Helen Khudenko - Of course, there are upgradable units in "Maelstrom", and there is also a unique principle of upgrade for each faction. The Remnants with their lack of technology and science rely only on themselves, their inventiveness and smartness. In this case units and vehicles are upgraded by attaching additional details, armour, weapons. Remnant Engineers use every single scrap piece and Remnant's forces look more and more "Mad Max's" style during the game. The Ascension, these cruel and merciless geniuses rely on the wide choice of transformable units. The upgraded tech has improved statistics and gains more options for transformation. The Aliens, who are an exclusively organic faction, actually are using minimum technology, they and rely mostly on biological processes, such as mutation.
