SWARMCORE FIELD GUIDE · MUTATIONS
Swarmcore mutations: build a readable plan
Understand the difference between a mutation deck and active upgrades, compare every current mutation, and plan movement, defence or attack combinations.
A deck is a plan, not every effect at once
Mutation Lab prepares two choices for each tier D, C, B, A and S: ten deck slots altogether. These choices do not mean ten abilities are active when you spawn. During a run, evolution opens tier choices; select an available upgrade to add its effect to that run. The arena keeps moving while you choose.
The cosmetic preview can demonstrate mutation visuals, but it is not evidence that every displayed effect is equipped in a live match. Read the names of your active upgrades in the game. All mutations are gameplay choices: there is no real-money upgrade that buys one for combat.
Three practical starting plans
Learning to escape
Long Jump or Slipstream can make repositioning more forgiving. Phase Loop supports repeated hops, while Emergency Field helps after losing a core layer or Endless life. These are recovery tools, not permission to remain outside the safe zone. Keep enough swarm to pay for a hop.
Learning the returning shot
Closed Loop rewards bringing pulses home. Pair the idea with a weapon upgrade suited to your aim: Ion Lance favours reaching across a gap; Echo Burst asks you to land successive hits. After firing, move to change the return path rather than standing still and waiting.
Playing close to the boundary
Repulsor Coil strengthens the nearby Q push. Fracture Code widens the opportunity to break a weakened core. This combination depends on position: a push used too far away will not turn a fight. Keep an exit route for yourself before trying to force a rival into danger.
Current mutation catalogue: 21 options
These names, tiers and effects are taken directly from the game’s mutation definitions, so the catalogue follows the same balance values as the build.
Tier D
- Long Jump utility
- Phase Hop travels 35% farther and recharges 3 seconds faster.
- Gravity Well utility
- +40% pickup range.
- Slipstream defense
- Move 12% faster to escape incoming fire.
- Devourer offense
- Loose energy restores 25% more swarm for your next shot.
Tier C
- Phase Loop utility
- Phase Hop cooldown is 8 seconds shorter.
- Bastion Shell defense
- Focus blocks 70% damage; its Endless shield arms sooner.
- Phase Cycle offense
- Pulse cooldown is 25% shorter.
- Closed Loop utility
- Returning pulses recover 18% extra energy.
Tier B
- Echo Burst offense
- Fire twice 0.14s apart. Each hit is weaker, but landing both deals more than one normal pulse.
- Trident Volley offense
- Split the shot three ways. Each hit is weaker, but landing all three deals much more than one normal pulse.
- Repulsor Coil defense
- Q pulse is 35% stronger and recharges 4 seconds faster.
- Ion Lance offense
- A larger cannon gives +25% pulse speed and +45% range.
- Overcharge offense
- +30 maximum swarm and stronger pulses.
- Flash Capacitor utility
- Charge a full pulse and its shield 25% faster.
Tier A
- Emergency Field defense
- Losing a core layer or Endless life instantly readies Q and extends protection.
- Fracture Code offense
- Core-breaking threshold is 30% wider.
- Life Siphon utility
- Hits restore 20% of dealt damage.
- Aegis Bloom defense
- Restore one core layer, or one life in Endless.
Tier S
- Stormborn utility
- Storm damage occurs half as often; in Endless you move 10% faster.
- Phoenix Protocol defense
- Prevent one elimination and reboot in place with one life.
- Titan Genome offense
- +50 maximum swarm, stronger pulses and +1 core layer outside Endless.
What to test before changing the whole deck
Try one new choice in Solo Lab, then compare the same situation in Practice. Were you out of swarm when you needed to escape? Did all parts of a split shot connect? Were you losing to the red zone rather than to incoming shots? A defensive change will not fix an aiming problem, and more weapon range will not fix a late retreat.
Keep one familiar choice while testing another. That makes the effect easier to recognise and helps you build a plan around decisions you actually use.
