Alterations let you fine-tune how your turrets and hulls behave. Where upgrades make your equipment flatly stronger, alterations let you shift the balance of an item's stats to suit your playstyle — trading a little of one quality for more of another. They are the finishing touch that turns a good build into your build.
What alterations do
Each turret and hull has a set of alteration options that adjust stats such as:
Damage — raw output per shot or per second.
Reload / rate of fire — how quickly you can keep firing.
Range & accuracy — how far and how precisely you hit.
Speed & turning — how nimble your hull feels.
Special-effect strength — e.g. burn duration, freeze rate, splash radius.
Alterations usually involve a trade-off: pushing one stat up may gently lower another, so there is no single "best" preset — only the one that fits how you play.

Tips for using alterations
Tune to your weapon's strength. Lean into what a turret already does well rather than fighting its nature.
Match the map. A precision alteration shines on open maps; an aggressive one suits tight arenas.
Experiment. Alterations are reversible, so try different setups and keep what feels best.
Combine with the build. Alterations work alongside micro-upgrades, paints and modules — think about the whole tank, not one stat.
Alterations are about personalisation. Two players on the same hull and turret can feel completely different depending on how they tune it — find the setup that clicks for you.
