Dawn of War II will be getting some free DLC in October with The Last Stand, a new cooperative "Horde"-type mode for 3 players. Choosing from 3 commanders, players will fight against 20 waves of increasingly difficult enemies competing for the top score on the leaderboards.
What should you expect during these waves:
"There are 20 total waves, with every fourth wave containing a special enemy set. These waves can be thought of as boss waves. This could include an enemy Force Commander with two Apothecary’s that can heal him. Wave 16 is especially challenging as the game puts you up against a mirrored set of commanders that can use the abilities you’ve selected for yourself. Teamwork is necessary. Waves 17 through 20 were not in the build I played, but I was assured that they would contain even more surprises."
