Add realistic nuclear reactors including a breeder reactor type and cooling tower. The reactors must be controlled through integrated circuit interface signals. The thermal energy output is dynamic and depends on reactor's core temperature. The reactors require sophisticated designs of their cooling system and heat-pipe network. If the operational conditions aren't met then a reactor core meltdown with dangerous consequences occurs
Start with a special starter armor, which offers no protection, but includes exosceletons, robo ports, a fusion reactor and batteries. You also get 100 special (fast) starter construction bots and a few other basic starter items.
Death from above! Build autonomous flying drones and launch airstrikes on those pesky bugs.
Introduces different kind of flares which can be placed on the map to automate artillery targeting. [Mod does still work (I think), but the concept is flawed - you can't shoot accurately like this, there are too many factors involved]
