Boneshredder

The Boneshredder is a wonder weapon that first appeared in The Last Sabbath. It is a semi-automatic revolver that utilises high-explosive incendiary rounds, that explode upon impact.

Effectiveness
The Boneshredder is very effective against hordes, as it's fairly blast radius combined with the following spread of fire can easily kill enemies. However, these effects are very dangerous to the player, and it's fairly short range compared to some weapons doesn't help with the use of this weapon. It is strongly recommended that you buy Dehazardous Sap if you are planning to use this weapon.

Skelecrusher
When Pack-a-Punched it becomes the Skelecrusher. This upgrade will increase the explosive damage, the fire per second damage, it's range, and will also provide a few minor improvementsm such as having a slightly faster reload per round. The blast radius will also be slightly increased, which could possibly be disadvantageous to some players.
