I recieved both DLCs for Renegade Ops for free as part of the giveaway they did for anyone who bought the base game before a certain date. The Reinforcement pack adds two new characters to your roster. Crystal's van can generate a force field that repels enemy fire, and can be safely parked in and shot out of, while Blazemo's buggy can become invulnerable and spray flame around itself that heavily damages enemies. Blazemo is by far my favorite character in the game to play, and I heartily recommend this DLC for this reason.
