Behaviour
Interactive pulled out all the shots today ahead of the Founder’s
Program release for Warhammer 40K: Eternal Crusade, announcing a
massive 19 unique classes belonging to the 4 factions that will
battle for control come the games official release.
Each
of the factions, The Space Marines, Chaos Space Marines, Eldar and
Orks, will each offer players at least 4 unique class options, with
the Eldar faction having an additional 2 options.

Lead
Designer, Brent Ellison, took to the official website to offer an
insight on the development and design choices for each of the
factions and their classes in Warhammer 40K: 

“A
Space Marine class is very flexible – for example a Tactical Marine
can be excellent at mid-range anti-infantry with a Boltgun, be a
short-range vehicle killer with a Meltagun or take the sniper role
with a Stalker Bolter. An Assault Marine performs a very different
function depending on whether they equip a Jump Pack or a Storm
Shield and a Devastator can be in the front lines with a Multi-Melta
or stand far at the back with a Lascannon. They can also modify their
accessories to get more accuracy, survivability, etc., in their role.”

He
also goes on to explain that today’s announcement highlights just the
basic class options, with Elite and Hero class reveals scheduled for
a later date.
The
official factions and classes can be seen below. For more information
