12 Mega Darts
The 12-Dart Chain was a Nerf chain that came with the RotoTrack. It was the last kind of chain released, and was the only black kind. It held 12 Mega Darts, and could be swapped for the Chainblazer's 8-Dart Chain, or the Razorbeast's 15-Dart Chain. It is no longer produced, like the other chains. Compared to the previous chains, this one proved more durable and reliable, most likely because of the black plastic used in its construction.
