The Undertaker

The Undertaker is one of the earliest obtainable guns in the game, depending on the created world. This will replace the Musket as the first gun found in game if the Crimson happens to replace the Corruption.

Similar to that of the Musket, The Undertaker can be found in Demon Hearts found in the Crimson Underground. The Undertaker with some ammo will always drop from the first Demon Heart destroyed on a world.

Despite being what could be considered the Crimson counterpart to the Musket, it seems to be more similar to that of a Flintlock Pistol, due to its weaker firepower and quicker fire rate. The Undertaker also sells for half the price of a Musket; at one gold coin.

Trivia

 * Resembles a revolver which gives the impression it comes from the time period based around the musket found in the corruption.
 * During the 1800s people were commonly buried by Undertakers, who would handle all the funeral arrangements much like a modern day funeral home. The weapon resembles an old west six-shooter, further reinforcing the reference to the era.
