Lanza Granadas

The Grenade Launcher (sometimes referred to as rocket) is an automatic projectile weapon that is centered around fast horizontal and vertical movement.

It fires a projectile which flies in an arc, exploding either on impact with another tee (not yourself) or any solid block. Any tee close to the explosion will get pushed away from it, allowing them to gain speed.

Horizontal Movement

To gain horizontal movement speed:

Walk in the desired direction
Shoot rockets in the opposite direction in the ground

Each explosion will propel you forwards, you will keep the gained speed as long as you keep walking in the same direction. Note that you can still jump and keep the same speed.

One grenade won’t get you very far. You can combine many tricks to get much further, for example:

Shoot one grenade up first for two simultaneous explosions
Use multiple grenade shots to the side
Get speed with other tools before the first explosion (e.g. by using the hook)
Rocket jumping on the last grenade shot

Rocket Jumping

Rocket Jump is a technique that allows you to jump much higher using the momentum created by a rocket shot.

Shooting downwards without jumping can get you up to 4#08 = 4.25 tiles.

To rocket jump:

Aim downwards
Jump, shoot right after

The delay between the jump and the explosion must be timed well.

Shoot too late, and you won’t get very high
Shoot too early, and you will already be off the ground for the jump. That will then cause you to double jump, which cancels your momentum

Using Walls

Similar to getting horizontal movement by continuously shooting at the floor, you can boost yourself up a wall by shooting at it at an angle. It is important to stay directly next to the wall in order to take advantage of the explosions.

Stand directly next to the wall
Rocket jump up
Aim downwards, in the direction of the wall (about 45°)
Continuously shoot, while staying next to the wall by moving in its direction

Once you run out of upwards momentum:

Continue shooting till you will begin falling
Double jump, directly followed by another shot
Continuously shoot again, while still staying next to the wall by moving in its direction

On some parts you will need to switch to the opposite wall while on the way up.

If the wall is close, you can switch to it without interrupting the rhythm.
If the wall is further away, you can propel yourself to it using a rocket and then use the double jump to continue upwards.

Double Rocket Jump

The double rocket jump (aka ‘double rocket’) is a more advanced version of the rocket jump.

It works by having 2 simultaneous rocket explosions (instead of just one) below you right after your jump.

Shoot on rocket straight up
Wait until it explodes below you
Do a regular rocket jump

It didn’t work?

If the two explosion didn’t happen simultaneous, try to adjust your timing with the rocket jump.
If you still didn’t get very high or lost your double jump, try to jump a little earlier

This trick is hard to pull off consistently.

Triple Rocket Jump

Triple rocket jumping is much harder than the double rocket jump.

Start by doing a double rocket jump
While falling down again, fire 2 rockets straight up (hold the firing key, the second rocket should be shot about when you land)
If timed correctly, the 2 rockets will explode at the same time below you
Couple the 2 rockets with a regular rocket jump for the triple rocket jump

Debido a la precisión de los tiempos, los rocket jump triples son demasiado difíciles de lograr consistentemente.

Comportamiento Avanzado

El proyectil de granada explotará si se mantiene en el aire por cierto tiempo.
El proyectil de granada no tiene anchura, lo que significa que técnicamente puede pasar por los espacios pequeños entre bloques. Para que funcione a propósito, ten en cuenta que es más fácil cuanto más cerca estés de estos.
Dado que el lanza granadas es un arma automática, puedes mantenerte disparando indefinidamente al descongelarte, incluso si estás dentro de una entidad de freeze.
Si reapareces mientras tu proyectil de granada está en el aire, este desaparecerá.
