PCB DEFENSE

Project intro

PCB DEFENSE is a fast, circuit-board-themed roguelike tower defense you play free in the browser. Your CPU core just went hot: hostiles crawl up every copper trace, and the only thing between them and total core failure is you — a BIOS cannon, turret pads and whatever is left in the salvage bin. Plant turrets on glowing pads and upgrade them through 6 tiers, chain kills into combo multipliers up to x3, and keep the core's energy grid alive while the swarm gets smarter every level. Four weapon systems (BIOS Bolt, Laser, Plasma, Rail) each have a full skill tree; boss fights land every 3 levels with multi-phase bosses that enrage as they take damage; beating a boss earns a Corruption Card, a run-altering debuff with harsher tiers the further you go; and Persistent Skill Points carry over per weapon, so every attempt makes the next one stronger. It is mouse-driven with optional hotkeys, takes a few minutes per session, and the page is actively updated: v3.7.0 shipped 2026-10-15, a leaderboard update marked 1,500 players on 2026-10-23, and the page itself was updated 2026-10-23. It also placed 1st in Super Free AI Game Jam #1 and Newbie Game Jam #1. No GitHub star count applies — this is an itch.io browser game, not a GitHub repo, so no star number is claimed. How it was made, from the game's AI Browser Game Jam 5 entry (verbatim): AI Tools Used — "I started out focusing on DeepSeek; with the latest updates, it's now Mimo v2.6." The itch page also carries an AI Disclosure of AI-assisted code and graphics. Free to play, HTML5, English, high-contrast accessible.
