The Club12 is a fictional lever-action shotgun designed by Krinkels. It is used by Deimos in CHASE.fla to zipline down a chain and kill three A.T.P. soldats that were seemingly pursuing him. After the soldats are killed, Deimos discards the shotgun to operate the gravity-altering lever. The shotgun falls into the sky (along with Deimos) when he reverses gravity.
The weapon appears again in Madness Combat 9.5 Part 2, where a Soldat uses it against Hank. Hank dodges the shots and quickly kills the Soldat with a Baseball bat. The shotgun falls to the ground and is not used afterwards.
The shotgun's handguard, Ejection port, and stock shape make it look similar to an Adler A110 shotgun with a "mare's leg" barrel/stock configuration.
The Club12 was drawn during one of Krinkels' livestreams of animating CHASE.fla. He had originally drawn a shotgun with a blockier design, but the animation program crashed before the shotgun was saved, necessitating re-drawing the weapon. The original shotgun can be seen to the right.
The Club12's name originates from its sprite file name seen in one of Krinkels' livestreams.
The “12” in the name suggests that the shotgun is 12 gauge.
