About this game

Bio Defence is a strategic tower defense game where your mission is to protect your base from relentless waves of viruses and bacteria.

Dangerous pathogens are attacking, and only your defenses stand between survival and total infection. Build, place, and upgrade powerful defensive systems to stop enemies before they reach your base. Each wave becomes stronger, faster, and more unpredictable, forcing you to constantly adapt your strategy.

Different enemy types require different approaches, from fast-moving viruses to more durable bacterial threats. Plan your defenses wisely, combine upgrades, and create the perfect setup to withstand the infection.

Game Features:
• Intense tower defense gameplay
• Unique enemies: viruses, bacteria, and mutations
• Upgradeable defenses and strategic depth
• Increasing difficulty with each wave
• Clean, engaging visual style

Test your strategy, react quickly, and survive as long as possible.

Can you stop the infection and defend your base?
