Abyssal Dome | Kingdom Defense HTML5 Game

Abyssal Dome — Defense of the Kingdom

Defend the last glowing dome in the abyss. Abyssal Dome is a polished, single-file HTML5 tower-defense game. Build turrets around your dome, earn pearls from fallen enemies, and hold the line against ever-deepening waves of sharks, crabs, jellyfish, hammerheads and leviathan bosses. No dependencies, no build step, no external requests — it runs anywhere a browser does.

Gameplay

• 5 weapons — Harpoon, Cannon, Sniper, Shock Coil and Mines, each with a Tier-II upgrade
• 8 weapon mounts — expand the Dome to add turret rings
• 6 enemy types + boss — Shrimp swarms, Crabs, Sharks, Jellyfish (that jam your weapons), armored Hammerheads, and the multi-phase Orca Leviathan
• Active tools — Sonar blast, Dome Repair, and Dome Expand
• Between waves — permanent upgrade cards, Royal Events with story choices, and a pearl shop
• Level select — jump to any of 100 depths, from the shallows to the endless Abyss
• Pearl collection FX — watch pearls fly from every kill to your counter
