The Grenade Launcher used with Rocket I. Note the bouncing ability of the grenade.

The Grenade Launcher is a Hardmode, post-Plantera launcher that consumes rockets and launches a grenade with a timed fuse. The grenade explodes when the fuse expires, or if it comes into contact with an enemy. The Grenade Launcher has a 14.29*1/7 (14.29%) or 16.67*1/6 (16.67%) chance to be dropped from Plantera, and on non-Expert or Master Mode worlds, it is guaranteed to drop the first time Plantera is defeated. In addition, 50–149 / 20–49 Rocket Is will be dropped alongside the Grenade Launcher.

Its best modifier is Unreal.


  • The grenades fired from the Grenade Launcher are strongly affected by gravity and can inflict massive self-damage. For this reason, using it in any tight area requires exceptional care to avoid it bouncing back to the player.
  • Selenians cannot reflect the grenade as it will instantly explode on contact.


  • Compared to the Rocket Launcher, the Grenade Launcher can be obtained much earlier but has an arc and will not explode on contact with blocks right away. The Grenade Launcher also deals 33.33% / 10% more damage.


  • Despite the name, the Grenade Launcher cannot fire Grenades, as they are hand grenades and are incompatible with it.
  • Despite being the first launcher that the player can obtain, it fires special projectiles instead of rockets.
  • Its firing sound is atypical for ranged weapons, resembling that of a spring-loaded mechanism. This makes sense as an explosive propellant would likely detonate the grenade prematurely.
