The new general units for each race in Dawn of War 2: Retribution's single player campaigns will also feature in multiplayer mode. Relic have revealed some of the special abilities that will be available to the Tyranid Swarmlord and the Eldar Autarch.

Tyranid Swarmlord


Once you've upgraded your base to tier 3 you'll be able to deploy a Tyranid Swarmlord to the battlefield. In single player the Swarmlord has a direct connection to the Hive Mind, and is responsible for gathering Tyranids together to spawn an army. In multiplayer the Swarmlord won't be able to spawn troops personally, but units near him will move faster, and fallen allies can be reinforced without having to flee back to base. In addition the Swarmlord's four bone sabers make him devastating in close combat.

Abilities:
Leech Essence
The Swarmlord drains the life from surrounding infantry units for a duration which increases his health regeneration.

Blade Flurry
Unleashes the full strength of the Swarmlord, heavily damaging and knocking back adjacent infantry.
Eldar Autarch


Unlike the Swarmlord, Eldar players won't be able to train and deploy the Autarch from base as with ordinary units. Instead the Autarch takes the form of a special ability that can be activated once enough kills have been made. Upon activating the Autarch the play gets to hand place the landing points for a volley of grenades. Once triggered the grenades will be called in from the sky, once they've gone off, the Autarch crash lands to clean up the aftermath. Once the Autarch's work is done, she vanishes from the battlefield, ready to be called upon again at a reduced cost.

Abilities:
Fleet of Foot
Greatly increases the unit’s speed but reduces the Autarch’s damage output for the duration of the ability.

Leap
Soar through the air and land at the targeted location. Upon landing the Autarch increases the speed, damage, health and of nearby infantry units.
