The virus outbreak wiped out almost the entire population, forcing you to fight for survival against the undead. To make it through the increasingly difficult levels, you must learn to use a variety of weapons to combat the hordes of zombies. By far the most powerful weapon is the Rocket Launcher. This guided rocket can easily be guided to the target, and once the rocket hits the target, the explosion will not only damage the target but will also damage any nearby enemies. The virus spreads through bites, so to survive, you need to use a variety of weapons. 

In this game, you will also have to shoot loot boxes to get the power-ups that can help you. There will also be several missions for you to complete, and you have to choose the right weapon for every mission.
