Bio Zone is a tower defense game where you gotta place and mash up weapons to take down those zombie hordes. It’s set in a post-apocalyptic Earth, totally trashed by pollution and crawling with mutated baddies. Your base is the last stronghold standing in the chaos, and as the big boss, you've gotta protect it at all costs. Smash zombies to rack up coins, then use them to buy starter weapons. Mix those low-tier weapons into epic ones at the fortress hub to crank up your firepower. Keep those zombies from wrecking your base!
