- This article is about the ammunition. For the novelty furniture items, see Firework Rocket.
Rockets are a post-Plantera form of Ammunition, sold by the Cyborg, and fired by the Snowman Cannon, Rocket Launcher, Grenade Launcher, and Proximity Mine Launcher.
There are four varieties, each with two significant defining traits: area of effect, and the ability (or lack thereof) to destroy tiles. Rockets I and II have a small area of effect, closest to that of a Bomb or Grenade, while Rockets III and IV have an area similar to the blast radius of Dynamite. Rockets I and III will leave tiles unaffected, while II and IV will displace all destructible tiles in their blasting radius.
- All rockets have splash damage that will harm the player if fired too close, except when using the Snowman Cannon. It will not damage other players unless PvP is enabled.
