A closer look at I rebuilt my browser tower defense 5 times based on player feedback

What PCB Defense is

PCB Defense is a circuit-board-themed tower defense with roguelike and incremental elements where you defend a CPU core using a BIOS cannon and turrets placed on glowing pads.

Gameplay emphasizes short runs: plant turrets, upgrade them through tiers, chain kills for combo multipliers, and survive increasingly smart swarms with boss fights every three levels.

What you actually do in the game

Place turrets on turret pads, upgrade pads through six tiers, and control a core cannon that auto-fires when aimed near threats; you can manually recharge the energy meter.

Choose and develop four weapon systems (BIOS Bolt, Laser, Plasma and Rail) each with an Offense/Defense/Economy/Utility skill tree plus weapon-specific branches, earn Persistent Skill Points across runs, select Corruption Cards after bosses for run-altering debuffs, and trigger Swarm Surge for a short flood of extra enemies and cash.

Controls, platform notes, and current state

The game is mouse-driven with optional hotkeys: left-click to place turrets and press UI buttons, right-click to upgrade pads or the core's BIOS damage, and ESC for pause/settings/save. Hovering the cursor aims the core cannon and can collect drops.

The developer is actively updating the game (multiple recent version updates and notes about mobile adjustments), and they respond to player feedback in the comments and patch notes.

Who will enjoy PCB Defense

Players who like fast, challenging tower defense with progression between runs and deep weapon skill trees will find it appealing.

Those who prefer clear tutorials may need patience: some players report unintuitive early-game elements, and mobile support has been adjusted but may still be in progress.

What weapon options are there?

Are there persistent upgrades between runs?

Yes - Persistent Skill Points earned each run carry over per weapon so runs make your weapons stronger over time.
