Mod units are units that were never used or cut out from Universe at war. Most of these mods are about making the Humans as a full fraction in skirmish battles.
The most complete human mod is called The Human Resistance. The mod includes all of the human units and structures from the campagin along with some of the cut units. These units include the Marvick jet, Dragoon, science team, Dragonfly, and APCs. The heros Moore and Woolard. The mod also comes with a new feature for the humans, resource collection. The resource structures look like landing pads but act like the Masari matter engines. The final part of the mod for the humans is that they have increased damage, especialy the marine units.
