A '''Bomb Space Jump''' ('''BSJ''') is a height technique that takes advantage of [[Instant Morph/Unmorph|Instant Unmorphs]]. It allows you to immediately unmorph and jump after you have done a Single, [[Double Bomb Jump|Double]], or [[Triple Bomb Jump]]. The key is to be in an area in which you are able to get an Instant Unmorph, as it otherwise is impossible to do this technique.


There are several types of BSJ, including a single BSJ all the way up to a 3BSJ.
It helps to hold L after you have started jumping so that you can jump higher/farther.


To perform a BSJ you need to set up the camera as stated before to provide an instant unmorph at some point in your bomb jump. Lay a bomb (or series of bombs) and let them hit Samus in Morph Ball. Hit X to unmorph Samus 21 frames (or earlier) and immediately press B after unmorphing to perform a jump while in midair. You can do a full Space Jump from this, if you have it.

** If doing a 2BSJ, lay two bombs in succession after the first bomb explodes, then unmorph
** If doing a 3BSJ, lay three bombs in succession after the first bomb explodes, then unmorph
* Jump after the Instant Unmorph

A Bomb Space Jump (BSJ) is a height technique that takes advantage of Instant Unmorphs. It allows you to immediately unmorph and jump after you have done a Single, Double, or Triple Bomb Jump. The key is to be in an area in which you are able to get an Instant Unmorph, as it otherwise is impossible to do this technique.

It helps to hold L after you have started jumping so that you can jump higher/farther.

General Steps

  • Lay the initial Bomb
    • If doing a Single BSJ, unmorph after the bomb explodes
    • If doing a 2BSJ, lay two bombs in succession after the first bomb explodes, then unmorph
    • If doing a 3BSJ, lay three bombs in succession after the first bomb explodes, then unmorph
  • Jump after the Instant Unmorph

Prime

In Prime speedruns, BSJs are very rarely used. One notable trick that requires the Bomb Space Jumps is Elevator Access A, which is the first shaft in spiderless shafts. Another use of the trick is in Phazon Core.

BSJs in Prime use 1 or 3 bombs.

Echoes

BSJs are quite commonly used in Echoes speedruns.

The most common and applicable way to be in a good position is to have your back against a wall. An easy way to achieve this camera position is to have your back to the wall, and then briefly move forwards and morph. Also, you want to be moving backwards as you are popped up from the bombs in order to facilitate getting the Instant Unmorph (assuming that you are doing the standard setup where you back is to a wall). There are some other cases in which you might want to be moving forward as you are launched up. Again, it all depends on what it takes to get the Instant Unmorph.

Corruption

Just like in Echoes, BSJs are also common in this game. BSJs in this game can be combined with Spring Ball. The initial bomb can be a Spring Ball instead. There are two BSJs used in Corruption:

  • Bomb Space Jump/Spring Space Jump (BSJ/SSJ)
  • 2 Bomb Space Jump/Bomb Spring Space Jump (2BSJ/BSSJ)
