Command & Conquer: Tiberian Sun

Command & Conquer: Tiberian Sun is a real-time strategy game and the direct sequel to the original Command & Conquer, set in the year 2030.

The Earth is now heavily contaminated with the alien crystalline substance known as Tiberium and is becoming less habitable with time, while new life forms have formed in areas of serious contamination. While the Global Defense Initiative (GDI) still has a technologically advanced arsenal, it is also tasked with Tiberium research and abatement. The Brotherhood of Nod suddenly re-emerges from hiding, and its leader Kane, believed to have been dead since the assault on Sarajevo in the First Tiberium War, unveils himself to General Solomon on GDI's orbital station Philadelphia. As Nod's sneak attacks start scourging the world like decades prior, GDI prepares for self-defense. Meanwhile, survivors of Tiberium mutation who call themselves The Forgotten live separated from society, but are about to become relevant for both GDI and Nod efforts.

Tiberian Sun debuted an isometric engine which combines the use of 2D sprites with 3D voxels (short for volume elements). There are even larger differences between the two playable sides in terms of gameplay styles and visual design - GDI prefers brute force while Nod specializes in hit-and-run tactics and the element of surprise. Some of the technologically advanced units include hovercrafts, subterranean flame tanks (aptly named "Devil's Tongues"), mechanized walkers, etc. Each side now also has multiple support powers at their disposal, and some of the special technologies have direct counters - stealth units can be discovered by mobile sensor arrays, while subterranean units can be directed further from sensitive areas with concrete pavement. The campaigns, similar to those in preceding titles, have side missions which can aid in resolving main missions (e.g. destroying a nearby outpost will reduce the size of the enemy army in the main mission).
