The first game in a series of strategy games. Initially, you choose which side you want to support - either the Global Defense Initiative, (GDI), aka the good-guys, or the Brotherhood of Nod, (NOD), aka the bad-guys.
You take control of the battle by means of manipulating soldiers, tanks, etc, and building a base. The further on you get in the game, the more your technology improves, and by the end you can make nuclear warheads.
The aim of the game is simple: annihilate your opponent.
This game is a lot more fun when played against other humans!
