SHRIMP GAME: OVERKRILL: All 21 Fusions
Fusing a shrimp in SHRIMP GAME: OVERKRILL means combining it with an elemental stone, which you can acquire either through Campaign or through Multiplayer. The stone’s element and the element your shrimp already has decide which Fusion you end up with, and every Fusion hands you a brand new Fusion Ability plus a buff on each of the two abilities your element started with. There are 21 Fusions and an achievement behind each one, so working down this list is also how you clear that set.

Two of the same element give the plus version: Earth and Earth make Earth+. Two different elements give a named Fusion, so Earth and Fire make Magma, Fire and Light make Solar, and Light and Dark make Lunar. Which half is the shrimp and which is the stone does not change the name. It does change the buffs, because a Fusion only ever buffs the two abilities that came from your shrimp’s own element. Steam, Aurora and Blizzard are the three to avoid on the Eel boss.
Every duration, buff and default key on this page is as of the launch build.

Fusion Achievements
All 21 achievements follow one pattern: the word Fusion, a colon, then the Fusion’s name. Earth+ gives you Fusion: Earth+, Smog gives you Fusion: Smog, and the same holds for the other nineteen. Each unlocks the first time you make that Fusion, so the grid above is the checklist for the set.
Earth Element Abilities
The Earth dungeon is the first dungeon in the Campaign, and an Earth shrimp starts with these two abilities.
Shell Crush turns you into a rock for a front flip onto the floor. Your shrimp is wrapped in Earth energy on the way down and slams into the ground, hurting any enemy it touches.

Boulder Burst lets an Earth shrimp summon a giant boulder from the ground. After a charge, the boulder damages anything it hits.

Fire Element Abilities
The Fire dungeon is the second dungeon in the Campaign. A Fire shrimp gets a dash and a fireball.
Blaze Dart sets you ablaze and dashes you in the direction you are aiming. It is a quick getaway, and it works as a way to surprise an enemy.

Flame Blast is the basic fireball attack a Fire shrimp gets. It will shoot a blast of fire with an area of effect and no piercing.

Light Element Abilities
The Light dungeon is the third dungeon in the Campaign. A Light shrimp gets a shield and a homing attack.
Shining Shell channels a shield around yourself that blasts on release. The shield greatly reduces the damage you take, and letting it go deals damage to enemies around you.

Homing Globes lets a Light shrimp lock on and shoot homing missiles at a target. You get three missiles across up to three different targets, and they last a few seconds.

Ice Element Abilities
The Ice dungeon is the fourth dungeon in the Campaign. An Ice shrimp gets a mist cloud and a beam.
Mist Sneeze sprays a chilling mist and does a backflip. Anyone who walks into the mist takes damage over time.

Frigid Beam creates a chilling ice beam. Your mobility drops while it is running, but the beam itself is surprisingly well controlled.

Wind Element Abilities
The Wind dungeon is the fifth dungeon in the Campaign. A Wind shrimp gets a spinning leap and a cyclone.
Twisty Swoop spins you upwards in a twisting formation. Use it to reach enemies sitting above you, or to break out of a jam.

Supreme Cyclone summons a giant cyclone that traps enemies. Escaping it is extremely difficult once an enemy is caught. It deals continuous damage, and anything still inside is destroyed after a short time.

Dark Element Abilities
The Dark dungeon is the sixth and final dungeon in the Campaign. A Dark shrimp gets a teleport and a spread of blades.
Ghost Blink shoots a teleport ball, and pressing F a second time detonates it and warps you. You appear where the ball was and deal damage on arrival.

Shadow Blades shoots a cluster of slicing blades. Five dark blades travel out horizontally and spread wider apart the further they go.
