榴弹枪
榴弹枪（英语：Grenade）／火箭（英语：Rocket）是一把全自动拋射武器（按住开火键即可连续不断地发射拋射物）， 持榴弹枪开火时会发射一枚水平与垂直速度极高的榴弹。
发射出去的榴弹会做出类似抛物线形状的弧线运动轨迹，当触碰到其他玩家身上或可碰撞实体时会爆炸（注：榴弹会穿过发射者本身）。任何靠近爆炸中心的玩家都会被冲击力给推开，因此榴弹枪允许玩家获得大量的移动速度。
水平移动
如何利用榴弹获得水平移动速度：
- 首先进行正常的水平移动；
- 之后向移动方向相反方向的地面上发射榴弹。
每次爆炸都会将玩家向前推动一些，也就是说只要玩家重复发射榴弹，就可以持续不断地获得水平移动速度。
一次爆炸不一定会将玩家推向很远的地方，玩家可以尝试将榴弹与其他技巧相结合，从而达到更远的距离，例如：
- 首先向正上方发射一枚榴弹；
- 在第一枚榴弹落地的瞬间，向移动方向相反的地面上发射第二枚榴弹（此时两枚榴弹应几乎在同一位置一同爆炸），之后持续不断的发射榴弹以获得更快的速度；
- 在发射第二枚榴弹之前，玩家可以尝试使用其他方法先获得一定的水平移动速度（例如使用钩索）;
- 在发射最后一枚榴弹时做榴弹跳。
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
Due to the precise timings, triple rocket jumps are insanely hard to pull off consistently.
Advanced Behavior
- A grenade projectile will explode if it remains in the air for too long [exact time?]
- A rocket projectile has no width, meaning it can technically pass through tight gaps between blocks. To get it to work on purpose, keep in mind that it is easier the closer you are to the gap
- Since the grenade launcher is an automatic weapon it can be held down to shoot indefinitely, also directly on unfreeze, even if you are standing in a freeze tile
- If you kill while a grenade projectile is in the air, the projectile will disappear
