This Onslaught DLC was probably some of the worst DLC I've ever played. I love Bad Co 2 to death, but this was just an excuse to get more money. It was repackaged maps with a twist on Conquest. They marketed it as the first co-op mode, but technically you play co-op with your team on regular multiplayer - co-op against another team of co-ops. I got my cheevos and I'll be sticking with the regular multiplayer and soon Vietnam.
