The short campaign and limited storyline is compensated by the high-quality content.

User Rating: 8.5 | Command & Conquer 3: Kane's Wrath PC
This is a very enjoyable expansion to an already superb game. EA has done well in implementing innovative new units to the three existing factions along with the addition of several new interesting sub-factions, each with their own particular strengths and weaknesses. Gameplay-wise these new units handle very well and there is nothing more satisfying than employing one of the three sides' Epic Units to utterly obliterate your opponent's base. Also, fans can rejoice as EA finally added the Global Conquest Mode to C&C, something not seen since Emperor: Battle for Dune, and the more recent LOTR: Battle for Middle-Earth games.
The single-player campaign is cleverly scripted and suitably challenging, rewarding hard-working players with revealed tidbits which tie-in to key events throughout the main story. Joseph D. Kucan as his portrayal of Kane nearly carries the story through all by himself in the cut scenes, exuding the usual megalomania-loving maniacal insanity we have all come to expect from the Brotherhood of Nod leader.
However, players will be left wanting with an unfinished storyline regarding the previous game's events. In particular, GDI's recovery during the aftermath of the Third Tiberium War. And the Scrin themselves; as they prepare to launch a full-scale invasion force on a supposedly unsuspecting Earth. Scant little information is given, and will leave many fans disappointed because of the absence of any solid conclusion.
Overall, the small yet well-done campaign, along with the immense replayability offered by Global Conquest (especially with multi-player), will keep gamers satisfied for a long time. If only EA had included GDI and Scrin campaigns to tie in the rest of the storyline, this may have been one of the best C&C expansions ever released.
