Right then, I think we all know that the Space Marine multiplayer community is rather small. It was never huge to begin with any the early bugs and whatnot scared people off.
Has Relic considered doing a free weekend through Steam? Unlock all multiplayer maps and modes, including DLC, for everyone. Existing players may have reason to purchase the DLCs, and people who have never considered it would get to try it out. It'd be a shame to see SM die so soon after release - relic needs to do something to get the community going again.
