Party Bullet

Party Bullets are one of 6 types of craftable ammunition for bullet-firing weapons. They may be crafted at a Work Bench once the Arms Dealer begins to sell Empty Bullets after Hard mode has been enabled.

These bullets may still be crafted Pre-Hard mode, provided that the player has obtained the necessary items for crafting them.

Trivia

 * They may be a reference to the "grunt birthday skull" from the video game series "Halo".
