Pirate Ships: Build and Fight puts you in command of a battered schooner and challenges you to transform it into the deadliest warship on the Caribbean. Build your ship on a tactical grid, equip cannons and crew, then send it into auto-battle PvP against ships built by real players.

This free online game runs directly in your browser on PLRun — no download required. Pirate Ships: Build and Fight is a tactical ship-building and PvP auto-battler developed by HeroCraft, a game studio known for the Zombie Derby series and other mobile and browser titles.

Originally released on mobile in late 2020 and brought to web browsers via WebGL in May 2025, the game has earned a 4.7-star rating from over 145,000 reviews on Google Play. The core loop is simple but deep: collect ships, cannons, crew, and artifacts, arrange them on a grid-based ship deck, then watch your build auto-fight enemy vessels in real-time combat.

With a Caribbean fantasy setting featuring sea monsters and cursed relics, dozens of ship types from schooners to battleships, and both PvP and PvE campaign modes, this browser game offers a full strategic pirate experience. It runs on desktop, tablet, and mobile browsers through its WebGL and HTML5 foundation. The game follows a Build → Battle → Loot → Upgrade → Repeat loop.

Every decision you make during the building phase directly determines your success in combat. On mobile devices, all interactions use tap and drag on the touchscreen. There are no keyboard controls — the entire game is played through point-and-click or touch input. Ship building is the heart of the game.
