Command & Conquer: Tiberian Sun An effective way of erasing any ground-based enemy unit when playing as NOD is to build two laser fence posts but place their beams across their main entrance to your base. The trick is to turn one of them off (but make sure you have sufficient power to have them both ON) and as an enemy unit passes over it, turn the offline post on, KAZAMM! Instant death to any enemy unit! Infinite Firestorm Wall: If you have a firestorm wall and it is fully charged, you can make it last forever without having to turn it off to charge. First charge your wall fully, then turn it on. Before it turns off or runs out of power sell or turn off your power plants until the words "On Hold" appear in the firestorm Icon. Your wall will stay on forever and will not run out of power until you build or turn on your power plants. - o -
