Usage
The Rocket Launcher is capable of firing Tier 1 missiles with any explosive warhead. To fire it, have a Tier 1 missile in your inventory along with the explosive type of your choice. Note, it must be a Ballistix explosive, and it must be the block form. Once this is done, hold the Launcher and Right-Click to fire!

Note: In Creative you can fire any missile, with any explosive without any delay.
