Zero Ballistics is a unique blend of first-person shooter and tank combat, focusing on multiplayer gaming exclusively.
The tank's body is controlled with standard keys W, S, A, D to drive forward, backward, left and right. The turret is controlled independently from the body and follows the movement of the mouse. Dragging the mouse to the left or to the right results in rotating the turret, while pushing the mouse forward or pulling it back controls the vertical alignment of the cannon mounted on the turret.
The tank is equipped with three different weapon systems. The main gun (default: left mouse button) fires projectiles that follow a ballistic trajectory. Therefore it is necessary to lead the target and aim higher if it is farther away. This weapon does a fair amount of damage, but the projectiles move with low speed.
The secondary weapon is a machine gun (default: right mouse button) that fires high-velocity rounds which have a limited range but follow a straight line so you should aim directly at your target. The machine gun does a rather small amount of damage. Depending on the chosen skill, tanks are equipped with a small number of mines which drop at the rear end of the tank's body (default: F). Mines do a high amount of damage if another tank runs over them, but can be destroyed by shooting at them, and have a limited lifetime.
Your tank also is equipped with a stealth device so you can only be seen by your enemy's radar when you are firing your main gun.
You can select the equipment of your tank in the equipment menu (default: E). Equip your tank with the weapons and skills that best fit your playing style! Changes you make here will take effect only after your next respawn.
The score table (default: TAB) shows each player's score, kills, deaths, level, and ping. Your accuracy and efficiency are displayed as well. For each kill, you are awarded two upgraded points, substantially weaker or stronger opponents give one or four upgrade points, respectively.
During the game, it is possible to upgrade the tank in the three categories weapon, armor, and speed. Each category has three levels that can be unlocked consecutively by spending upgrade points. Upgrade points are earned by killing opponents or helping somebody else kill an opponent.
The upgrade menu (default: U) shows a short description of each upgrade, together with upgrade costs that need to be spent to activate an upgrade. Upgrades can be activated via hotkeys (default: 1,2,3). Choose your upgrades wisely to gain an advantage over your enemies.
