"We are really playing up nighttime and light as important elements," says Yeo. "At night, everyone’s sight range is half, and there are spotlights that can track units near your base." In all honesty, the screenshots released thus far do not even begin to illustrate the true richness of the real-time dynamic lighting. GDI watch towers have spotlights that constantly circle the base and light up the deep blue terrain, sometimes picking up a Nod tank and starting to fire at it. Additionally, when the squeal of an air-raid siren is heard and red sirens roar, the entire base actually basks in a pulsating deep-red light. Especially in the arctic missions at night, lighting will be one of the most innovative strategic elements.

As for the locales of the missions -- the terrain sets -- Tiberian Sun will feature four: arctic, urban, temperate, and desert.

Civilians can be heavily armed, and there are hospitals that can be used to heal troops. The city mayor will also be a character in the game who will work with or against you depending on how you treat his city. So, go in and start blowing up all the buildings and the mayor may attack, but if you play nice, you might get a helping hand when in dire need of one.
