A simple mod adding a craftable weapon, the Gunlance from the Monster Hunter series.
One of my two early tests for a hybrid weapon in Rimworld. This one is a melee weapon with a reloadable ability.
Trying to be as close as I could to its mecanics in MH, the gunlance has very short range for firing shells, and only five charges before it must be recharged. The shots pack quite a punch, and are explosive, so be careful not to get caught in the explosion. If you time things right, you can shoot all your shells in quick succession for a huge chunk of damage.
Unlocks with gas operations.
