Throughout the day, I have been trying to find a way to make a grenade mechanic, but i'm not really experienced in doing that code. So as an apology, I decided to add bulletproof vests, which can give you body armor to survive longer. And I will definitely add a Upgrading mechanic, which allows you to upgrade your health, body armor, and your special ability duration (how long can you use the special ability). Please continue to play my game GunZone and I promise that I can make the better version  of the game.

With all love and thanks!
