Welcome to "Zombie Biozone Battleground"! A leak of a secret gas occurred at a classified military-science base, turning the entire personnel into zombies. You will take on the role of an experienced former military operative. Your task is to clear the area so that specialists can arrive and eliminate the consequences of the accident. For each defeated zombie upon returning to the base, you will receive coins that you can spend to purchase new gear and expand your weapon arsenal. The stronger the enemy, the more coins you will receive for defeating them. Accept the challenge, adapt to the environment, and rid the zone of the zombie threat! Good luck!
