"The design goal for Last Stand has always been that wargear would give you new ways to play, rather than straight-up be better. I've tried to maintain that design philosophy with these items," designer Clint Tracker explained in the announcement. "One, so that players do not have to buy it to compete for top scores and two, to stay true to the original intent of the mode. These items are here to create new and awesome ways for players to slaughter mobs of infantry in the two arenas."
Two new items will be released for each of the six Last Stand heroes, intended to be work together and support particular approaches. The Imperial Guard Lord General's gnarly bearskin shrug and shotgun, for example, will toughen up his turrets and help him tackle crowds of infantry. The Space Marine's snazzy new hat and shield, on the other hand, toughen him up and boost melee damage so he can happily go on hacking enemies to pieces.
Pricing for the DLC has not been revealed yet, though producer Jeff Lydell told GameReplays that it'll be "Purchasable per hero or in a bundle for the whole set." There's no word on a release date yet either. The previous DLC, a purely cosmetic Dark Angels skins pack, cost $7.50.
Presumably the new wargear will also be released for Dawn of War II - Retribution - The Last Standalone, the $10 standalone spin-off of Last Stand mode.
