The Adder is just a one-man, six-wheeled vehicle with a positionable launcher and two fairly big rockets. It makes a great anti-aircraft weapon, and is colored in Cobra blue. The downside is that once you fire both missiles, it becomes useless, since it has no other armament. For a small vehicle, the Adder is pretty nifty. Review by: Aaron
