Should I use C4 or rockets?

Short answer

Use C4 when the target is isolated and you want simple, concentrated direct damage. Use rockets when a well-aimed splash can damage multiple building pieces or when switching targets matters. Compare the complete breach path: one cheap layer does not make the entire route cheap.

Checklist

  • Count every confirmed layer, not only the first door or wall.
  • Mark intersections where rocket splash can hit another useful piece.
  • Compare total sulfur for the route with the free RaidBench calculator.
  • Carry the weapon, ammunition, seal materials, and one explicit stop condition.
  • Recalculate immediately if the breach reveals a different path.

Example

A vanilla stone wall is four rockets or two C4 in the current RaidBench table: 5,600 versus 4,400 sulfur. C4 is cheaper for that isolated wall, but rockets can reverse the decision if their splash meaningfully damages a second piece.

Common mistakes

  • Comparing one rocket with one C4 instead of the target's required count.
  • Assuming rockets are automatically better for every large raid.
  • Counting theoretical splash without checking the actual angle.
  • Crafting the full load before the route is scouted.

Frequently asked questions

Are C4 charges always cheaper than rockets in Rust?

No. Compare the number of items required for the complete route. C4 can be cheaper on an isolated target, while useful rocket splash can reduce the effective cost across multiple pieces.

Why do large groups often use rockets?

Rockets can apply splash damage, support target switching, and maintain pressure across grouped building pieces. Those advantages matter only when the route and firing angle can use them.

Should I craft C4 or rockets before scouting?

Scout first whenever possible. Crafting a fixed load too early can lock you into a poor route after the base reveals a cheaper door, wall, roof, or splash option.
