Warhammer Online: Warhammer 40,000: Dawn of War Hands On at IGN

IGN editors had a chance at a hands on experience with the Dark Eldar. Here's a portion of what they had to say:

As I found out playing a skirmish map, a large army of Dark Eldar infantry coming up against a fully prepared large army of Space Marines is going to need some serious help. Luckily, the Dark Eldar are equipped with powers that can be enabled by using up souls, which can be collected from freshly dead bodies on the battlefield by the tortured slaves. These abilities can temporarily imbue one unit with the ability to detect cloaked units, damage enemy morale, do direct damage and disable abilities, recharge friendly abilities, and reduce enemy armor. There's also the ability called Soulstorm that acts as the superweapon direct damage ability that can be directed around the battlefield to cause significant damage to enemy units.
