How to Build and Fire Custom Cluster Strikes with Shell Holders

Shell Holders allow you to pack multiple standard artillery rounds into a single container shell. When fired and detonated, the container deploys its stored sub-munitions mid-air for a customized cluster strike.

Packing the Shell Holder

1. Place a Shell Holder block down on the ground.

2. Hold your chosen cannon shells and right-click the placed holder to store them inside. You can load standard artillery variants—such as high-explosive, armor-piercing, shrapnel, mortar, or smoke rounds—into the container.

3. If you make a mistake or want to change your payload, sneak and right-click the holder with an empty hand to pull out the last loaded shell.

4. Once your sub-munitions are loaded, right-click the holder with a fuze and a tracer to configure its mid-air detonation timing and visibility.

Firing the Cluster Round

After configuring the payload and fuze, pick up the packed Shell Holder and load it directly into your Create Big Cannons barrel. Load your chosen powder charges behind it—using upgraded tier charges if you need extra muzzle velocity and range—and fire the cannon as normal. When the fuze triggers during flight, the holder will burst open and scatter your stored shells over the target area.
