Most people did not like the multiplayer. To be honest, I found it rather fun. I'm not strongly sided to single player, or multiplayer in games. I can care less if a good story game adds online competitive modes, as long as the story is still good. I'd rather buy a game with multiplayer so I have something to do after campaign and I haven't gotten enough. Condemned 2 had the standard game types, along with a type called Crime Scene, which is a good change in pace, Bum rush as well.
The Bloodshot Fight club was cool too, different solo challenges and all with leader boards.
There were glitches, the frame rate got annoying sometimes, and the player movement animations were unrealistic online, as well for Ethan Thomas o.o All in all, this game was a cool, scary, and brutal, time and you definitely should check it out.
