yeah they did, lots of new achievements. Achievements for beating the two new levels and achievements pertaining to the new last boss.
I gave one of the new levels a go last night. Pretty good. Really challenging layout and the locations etc were excellent. The addition of an actual proper last boss fight was really good IMO. Game actually feels complete now, and it was sweet how the DLC was free. Im pretty stoked with it. Cant put this game down for some reason, Ive been through it twice but it keeps giving you achivements at a steady rate. Im definitely going to go for some more single player achieves.
has anyone given the online a go?
