Martillo
The Hammer is a melee, semi-automatic weapon. It is fundamental for most techniques in DDNet and with the 
Pistol the only weapon equipped by default. The hammer unfreezes other tees, gives them an upward lift and pushes the hit tee a bit away from you. The fire delay is either 120ms or 320ms when you hit a tee.
Wall hammer
As the only melee weapon, the hammer has a relatively short range.
Any tees hit by its generous hitbox will:
- Get unfrozen.
- Get pushed away from the hammering tee.
The range of the hammer allows you to just barely hit tees behind a 1 tile thick wall.

Unfreezing
When you hit another tee, it will immediately unfreeze them.
1 Tick Unfreeze
If the tee you are hammering is currently in a freeze tile, they will immediately become frozen again. However, just like when hit by the Laser Rifle, the tee will unfreeze for a brief moment in which they can:
- Jump
- Move (only very little)
- Fire any weapon
- Hook (however since the hook has a very slight travel time it is only able to reach a short distance and affect other tees, about 4 blocks; the hooked tee will only move a very short distance)
With any weapon, the briefly unfrozen tee can hold down the fire button to fire instantly upon being unfrozen by the hammer. Using this you can create chain reactions using the 1-tick-unfreeze.
Movement Using Hammer
On top of being unfrozen, the hit tee will get a good amount of speed. While there are a lot of tricks with the hammer alone, combining it with other utilities allows for many more tricks.
Hammer run
Combines running speed with the horizontal speed from the hammer.
- The tee in the back initiates it by walking against the tee in the front
- The one in the front can then also begin walking in the same direction
- Now the tee in the back can hammer the one in front to give it speed
Hammer jump
Hammerjump combines jumping with the vertical speed from the hammer. It is essential that the hammer hit happens after that jump.
Advanced behaviour
- Although the Hammer is a semi-automatic weapon, it can be held down to shoot directly on unfreeze
- Counterintuitively, the hammer will never cause downwards momentum, even when the hammering tee is on top of the other tee. It will only cause sideways and upwards momentum
