Player 1: Player 2: Z-Shoot B-Shoot X-Defend N-Defend C-Reload M-Reload The goal of the game is to hit the other player while they are reloading. You only start with one ammo so you will have to reload eventually. If both players shoot nothing will happen. The defend action blocks any incoming shots from the other player. This will still take up the player's ammo, so if you anticipate when the other person will attack, defend. If you anticipate the other person will defend, reload. And if you anticipate the other person will reload, shoot. Ultimately, it's just rock paper scissors but with more strategy.
