Zombies have some of their basic control functions.

Arrows: Move the character when pressed. Note: If you press quickly it just changes to the character's direction.

Shift (pressed): Makes the character run instead of walking slowly. Note that in the inventory menu there is an option called "SYSTEM", you can switch to the mode that automatically runs the character without pressing shift and vice versa.

Q: Use a green pill to regain 75 LIFE points.

A: Attack or shoot. If you don't have anything on hand, the character will not perform an attack action.

S: Reload. Reload your current weapon's magazine. Note: It only reloads when the ammo counter is at zero.

B: Turns the flashlight on/off. It helps to lighten dark places, but note that it requires batteries to function.

N: on/off night vision goggles. Yes Zombies have night vision system. This item illuminates the character's vision with more intensity and perfection. Note: Uses battery. These glasses are hard to find.

X/Esc: Access the main menu. Then you manage your character, settings, items, weapons, accessories, check character status and so on.

Z/Enter: Action button or confirm. Important throughout the game.

Well these are the basic functions of the keyboard controls. Thanks and enjoy!
