Terraria

Terraria is a 2D clone of Minecraft. It also has guns.

Zapinator


The weapon mentioned by Blue as a weapon only owned by developers. It seems to be a reference to the NES Zapper, due to the similar name and sprite. As with other developer weapons, it is coded to become an Angel Statue in-game. It deals 50 damage and has insanely fast speed.

Initially, the Zapinator could be obtained via an inventory editor, but as of the beta release it was removed from the game completely and indefinitely.

Red Potion
A Red Potion was added in the 1.2.2 update, though only accessible with inventory editing. The potion gives the player Burning and Suffocation upon consumption.

Developer Armor
Sets of armor named after the developers (Red, Will, and Cenx) are in the game, but can only be obtained by use of an item editor. The tooltip displays "You shouldn't have this" for almost every piece, and equipping any of them gives the player a slew of debuffs that are able to kill in under five seconds.
