Fusions are one of the most important parts of Shrimp Game: Overkrill, especially once you start collecting different elemental stones. Each Fusion combines two elements and gives your Shrimp a new Fusion Ability while also changing how its elemental abilities work.
In this guide, I’ll go through all 21 Fusions, including the elements needed to create them, their Fusion Abilities, and the bonuses they give to your base elemental attacks.
There are six elements in the game: Earth, Fire, Light, Ice, Wind, and Dark. By combining an elemental Shrimp with another elemental stone, you can unlock every possible Fusion combination. Each Fusion also has its own achievement.

There are 21 unique Fusions in Shrimp Game: Overkrill.
The six elements are:

Fusion Achievements
There are 21 Fusions and 21 corresponding achievements, so collecting every Fusion is also the way to complete this part of the achievement list.
Since the six elements produce different combinations depending on the elemental stone you use, it is worth keeping track of which ones you have already unlocked.
You will also end up with 36 different elemental ability combinations across the Fusion system.
One Fusion to Avoid Against the Eel Boss
There is one important warning when experimenting with Fusions.
Be careful about using Aurora, Steam, or Blizzard against the Eel boss. These Fusions can cause problems during that fight, so it is better to switch to another setup before going into the encounter.
Apart from that, experimenting with the different Fusion combinations is one of the more enjoyable parts of Shrimp Game: Overkrill. Try different elements to see which Fusion Ability and elemental bonuses fit the way you like to play.
