The player arrives to this place which is kind of messy. Blocks are floating around, while two inactive cores rest in the middle.
If the player tries to activate only one core at a time, the blocks will surround both the one that was activated and the one that was not, preventing him/her to activate the other one with a bubble. The player must activate both cores at the same time.
The activated cores are now surrounded by blocks. However, these blocks used to hide emitters, which they don’t anymore. This will let the player activate them to transform the core. However, not every emitter can do it, due to their direction, angle and range. The player must find the two emitters that will let him/her transform the cores.
