A hastily-removed forum posts suggests Warhammer 40K: Space Marine's co-op multiplayer will be available post-launch via DLC.
The representative reportedly said the co-op mode would be patched into Space Marine around 30 days after launch, apparently delayed by a need for polish.
The post also seemed to suggest that the co-op patch will be free to those with a brand new copy of the game, but will be paid DLC for the second-hand market, alá Online Pass systems.
THQ has issued a statement confirming the game will include co-op and promised more details this month, although it did not comment on when the mode will be available.
Space Marine is due in early Septmeber on PC, PlayStation 3 and Xbox 360.
