Be smart.
You can be banned for not using the Hammer responsibly.

"A blunt tool designed to knock nails into things. Not much can be said about such rudimentary tools, other than the fact it can be used as a bludgeoning weapon if needed."
―Jay Effersson

Originally, the Hammer could only barricade structures by picking up planks spread throughout the map.

Later on, this was changed and it can now both construct buildings and barricade doors without having to pick up planks.

This can also be used as a melee weapon, if you so wish.

Background Story

Nobody knows how smashing a Hammer and paying some money allows you to spawn fences, sandbags and planks out of thin air, but don't worry about it. They're useful.



Smash: Basic melee attack doing 35 damage.

Consumes 6 energy.

Barricade: Used to barricade doors and windows.

Rotate: Used to rotate buildable items.


  • When using the Hammer, make sure to have enough money to build whatever you need, otherwise, it will be a waste.
    • The main page for this information can be found here.
  • You can use this as a melee weapon and it deals 35 damage per hit.
    • However, most melee weapons are much stronger than this. It isn't recommended to use this as a melee if you have a better melee.
    • This also doesn't trip zombies so in some cases Punching and Kicking is better.
  • The hammer has the Head shot effect (see.Status Effects, Loss of Head)

  • This was once abused in King Crab and in Lord Pumpkin Jr. (2016 only). People could spawn some buildings on top of destructible parts. When those parts were destroyed, they would be left floating in the air, practically invincible.
    • These have since been banned in all Quests, all PvP modes (including Undead Battleground) and all Bosses after Chronos XI for a similar reason.
      • To counter this, all Hammers equipped prior to the round will automatically turn into the Vitamins.
    • For unknown reasons, the Hammer is also banned in M.S Antares.
      • This is probably because buildings would float in midair when the ship sinks during Campaign.
    • The Hammer is banned in Buried Alive to prevent players locking themselves in mineshafts or the church.
  • This is technically the second melee to be added to R2DA.
  • Prior to v0.6.6, you could build on water.
  • Some areas of maps will have terrain/physical features that will prevent you from building.
