Bio Zone is a thrilling defense game that throws you into the heart of a post-apocalyptic world where the line between human and monster has blurred. Set on a 2000 Earth ravaged by pollution, you find yourself in the midst of a zombie-infested wasteland. Your mission? To defend a lone stronghold, humanity's last refuge, from a relentless horde of the undead.
How to Play
Bio Zone is easy to learn and fun to master. Here’s what you need to do to keep the zombies at bay:
Drag and Place Weapons: Use the left mouse button to drag weapons from the inventory onto the fortress. This is where you'll strategically position them to attack incoming zombies.
Merge Weapons: For a more powerful defense, you can merge low-level weapons to create higher-level ones. This process takes place on the fortress core interface. By doing so, you enhance your base's offensive capabilities.
Protect Your Base: The ultimate goal is to keep your stronghold standing. Zombies will swarm from all sides, so it's crucial to plan your defense meticulously.
Defeat Zombies to Earn Coins: As you fend off the zombie horde, you'll earn coins. These precious resources can be used to buy new weapons or upgrade existing ones.
Upgrade and Expand: Use the coins to purchase and upgrade weapons, or to expand your fortress. The more you upgrade, the more powerful your defenses will be.
