PCB DEFENSE

Your CPU core just went hot. Hostiles are crawling up every copper trace on the board, and the only thing between them and total core failure is you — a BIOS cannon, a handful of turret pads, and whatever's left in the salvage bin.

PCB Defense is a fast, circuit-board-themed roguelike tower defense built for one more run. Plant turrets on glowing pads, upgrade them tier by tier, chain kills into escalating combo multipliers, and keep the core's energy grid alive while the swarm gets smarter every level.

FEATURES

• Four weapon systems — BIOS Bolt, Laser, Plasma and Rail, each with its own stats, feel, and full skill tree (Offense / Defense / Economy / Utility + weapon-specific branch)
• Core cannon control — aim near threats to auto-fire, manage your energy meter, recharge on demand
• Turret pads — plant, upgrade through 6 tiers, and defend every angle of the board
• Combo chains — stack kills before the timer runs out for up to x3 reward multipliers
• Boss fights every 3 levels — multi-phase bosses that enrage as they take damage
• Corruption Cards — beat a boss, then choose a run-altering debuff from three, with harsher tiers unlocking as you go further
• Swarm Surge — cash in for a 10-second flood of extra hostiles (and extra pay) when you're feeling confident
• Persistent Skill Points — SP earned each run carries over per weapon, so every attempt makes the next one stronger
