The T-Bone dlc isnt out yet to my knowledge. The ones I had were the Palace pack which was basically a mission where you had to infiltrate a big mansion type house, and then chase a guy down. There was a mission to get the biometric assault rifle, which is the gun I pretty much use all the time now. I supposedly had the breakthrough pack which had something about scramblers, but cant say I noticed it in action.
To be honest as I had them from the off, it was hard to know what was and wasnt dlc unless it was marked on the map as exclusive mission, but I think that was the dlc that all Playstation owners got and X Box/PC owners didnt.
