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.
