Arc is an unused weapon from Cuphead. It would likely have been obtained through purchasing it in Porkrind's Emporium.
Strategy[]
The Arc shoots out placeholder Chaser bullet in an arc (as the name implies) and once the bullet hits the floor, it would stay for a while, getting bigger and possibly stronger as a trap for bosses that move, then it would disappear. The arc of the bullet can be influenced by the player(s) movements.
EX: Fires a small placeholder bullet and stays on the ground for a while, if it did not hit anything, it will explode automatically.
Trivia[]
- An also scrapped weapon like Arc appears in the DLC, called “Firecracker”. It explodes over time however. The weapon, however, is bugged.
- It’s possible the Arc is the Star Gun seen in various prerelease screenshots.
