The new mode, which will come as a free download for those who own the full game, lets three players select either the Space Marine, Ork or Eldar hero classes, then face off cooperatively against wave after wave of computer-controlled adversaries. Between waves, players will be able to level up their heroes and manage their equipment. The series' strategic roots aren't being thrown out the window -- players will need to work together to stay alive and capture score-multiplying control points.
We'll undoubtedly learn more about this intriguing expansion to the well-received strategy title during Relic's panel at PAX 2009.
