There's no doubt that Kane's Wrath has some flaws and unless you're a fan of the NOD, you'll probably feel a little cheated by the lack of a GDI or Scrin campaign. Still, Kane's Wrath is quite impressive nonetheless. It does exactly what a good expansion should - it follows closely in the footsteps of its parent title while also bringing something new to the table.
It exhibits the same sense of polish and depth that made the original Tiberium Wars such a classic. RTS fans who can't get enough of the Command & Conquer universe should definitely check this one out.
