## What is Proton?

Build a road that becomes a trap. Proton is a tower defense game where you shape the enemy route, choose your towers and place heroes at key positions.

Every turn matters on these floating islands. Extend the path beneath a laser beam? Hold enemies beside a trap? Strengthen a hero where your defense needs support? Make the call, then put your strategy to the test.

YOUR ROUTE. YOUR ADVANTAGE.
Add road pieces and expand your island. Plan the turns, tower positions and trap placements. A clever layout gives your weapons more time to fire and your base a better chance to survive.

BUILD YOUR BATTLE DECK
Combine lasers, Tesla towers, snipers, flamethrowers, discblasters and more. Each weapon fights differently, while upgrades and modifications give you new ways to stop the next wave.

SIX HEROES. YOUR TACTICS.
Aurion, Etherion, Verdant, Seraphion, Aster and Viryx bring distinct abilities and roles to your defense. Viryx coats the road in acid that poisons enemies; his modifications add slowing and strengthen the spill. Choose their positions and develop their strengths. Your heroes attack enemies automatically.

BLUEPRINTS FOR STRONGER DEFENSE
Collect weapon blueprints and merge three matching ones to raise a tower or trap’s quality. You can also sell blueprints for gold.

RUNES THAT CHANGE THE FIGHT
Three slots per hero. Six rune types: health, damage, attack speed, evasion, critical hits and lifesteal. Merge three matching runes of the same type and level into a stronger one, and upgrade them all the way to level VI.

STRENGTHEN YOUR WHOLE DEFENSE
Spend tokens in a research tree with four branches: towers, heroes, runes and your base. Choose the next upgrade to suit the way you play.

ADAPT TO THE ENEMY
Armored giants, portal-casting witches, devourers and burrowing machines demand different tactics. Study them in the enemy guide, prepare your defenses and earn three stars for a flawless victory.

Shape the path. Assemble your team. Hold the base.

Available in English, Ukrainian and Polish.
Optional rewarded ads let you claim extra rewards.
