This is a set of add-ons for use with any of the Rumble Cars remote-controlled combat vehicles. These accessories, which snap on in place of the pieces that come with a Rumble Car, look great ("tough," as we used to say when I was in the target demographic for this stuff), adding an element of stylish menace, but it's important to note that they don't actually extend what the cars can do. So the missile launcher included here, while it may scare your opponent, does not function as a weapon. Still, these accessories can add interesting variation to your basic Rumble Car setup. --David Stoesz
