The units they are revealing are multiplayer units and campaign heroes. Let's break down what they've released so far by race.
The Eldar will have 4 heroes available to them in their campaign:
- Kayleth, an Eldar Autarch who leads the Eldar of Craftworld Alaitoc
- Ronahn, a former Pathfinder of Craftworld Ulthwe who renounced his ties to that Craftworld and wanders the stars
- Veldoran, an aged and wise Warlock
- Elenwe, a Farseer who helps guide Kayleth through the Eldar campaign.
The new Eldar multiplayer unit is the Eldar Autarch:
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.
Skyleap – The Autarch jumps high into the atmosphere, returning to the global ability bar to be called in for a reduced cost.
The Autarch descends to the battlefield when called in from the global ability bar. The unit can be dropped into any hot spot on the map, provided you have line of sight on the drop zone.
The Tyranids have a unique campaign that has only 1 hero, the Hive Lord who strives to bring together the scattered remnants of the Tyranids in the Aurelian Sub-Sector.
The new Tyranid multiplayer unit is the Tyranid Swarmlord:
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.
The Swarmlord isn’t going to be on the field until late in the game, given its cost and the Tier 3 requirement. The Swarmlord’s status as a powerful late game unit results in it being nearly unstoppable in melee combat, wielding four bone sabers, but it also increases the movement speed of all Tyranids within range of its synapse.
No Campaign Hero information has been released yet, but you can guarantee I will be watching very closely for that news.
Deff Rolla Rampage – Spin up the Deff Rolla for a short period, knocking back and potentially crushing nearby infantry. Temporarily increases the speed of the Battlewagon.
Mega Boomshot – Fire an explosive long-range artillery shot. Deals heavy damage to most units.
An expensive late game unit, the Battlewagon can tear into enemy formations and receive little damage. It is a heavy assault transport vehicle that has anti-vehicle as well as anti-infantry weaponry.
Okay needless to say this is all such cool news. But the coolest news is the Ork Battlewagon. Oh my god, I cannot wait for that unit. And a Deff Rolla Rampage? You can better believe I'm looking forward to lining up some non-greenskin scum in my sites and runnin' 'em down wit da rolla! Definitely March 2011 is way too far off.
