The only DLC on sale is the mission packs which only add a few hours of content. I'd say wait for a further reduction as it's pretty fun, but the game was rushed and thus lacks content. --- SRWG-W - http://www.srwg-w.org/ Are we not men?
It's a great game, it was several steps in the right direction with only a few missteps. I think the story missions should have been more unique instead of just playing side actives with a story cut scene to explain why you're driving with a tiger. But it's very worth the low price, 17 bucks and the season pass is marked down to around 7 bucks. Most of the other DLC are costume packs and extra weapons since THQ loves to nickle and dime their DLC more than any other company, but they really are hurting for money too.
