You will play for one special task force armed to the teeth, which is destined to put an end to this epidemic. To end it, you need to kill the leader, who continues to spread the infection. To stay alive from you will require good firing accuracy and cunning. The gameplay itself is very addictive especially when there are cheats in the game allowing one to add cartridges to the button or to cure oneself using the second button. In addition, there is the possibility to make endless cartridges by the number 5 and health 6. And if you need to replenish the arsenal, and the money is not enough, use 9 and 0 to add upgrade points in the game Madness: Project Nexus with cheats.
