IGN reviews Kane's Wrath!

The single-player campaign feels disjointed, mainly because it jumps all over the Command & Conquer timeline to fill in the gaps. Things start off just at the end of the Second Tiberium War, and every few missions the campaign leaps forward a decade or two. As such, you don't get much of a cohesive story. Instead, you get glimpses of the back story. While prior knowledge of the previous games isn't necessary, it would certainly be helpful in understanding what's going on.

Meanwhile, there's the standard selection of RTS mission styles in the campaign. Most of them have you begin with a construction unit, which you use to construct a base. That includes a refinery or two to start harvesting tiberium, some power generators, and a variety of infantry or vehicle factories, along with support buildings that unlock special powers and abilities. The formula in these is usually build up your forces till you're strong enough to go on offense, and then attack and repeat until you've worn down the enemy. Then there are a handful of non-building missions, where you control a small group of units and must navigate around the level without losing too many of them. Here the trick is to save early and often until you get through the level.
