Instructions
Use the "W" and "S" keys on your computer keyboard to move forward and backward, respectively. In "Combat Arms," these keys work identically to the arrow keys in many other games. Hold the "W" button down, for example, to move forward in a continuous motion.
Use the "A" and "D" buttons on the computer keyboard to move left and right, respectively. Hold these buttons down to move left or right in a continuous motion. Release either of the buttons to have your character stop moving.
Move your computer mouse to change the direction that your character is looking. If you want your character to look to the right, move your mouse to the right of your mouse pad or desk top.
Combine the use of the "W," "S," "A" and "D" keys as well as your computer mouse to move and turn at the same time. If you want to move forward and to the right of your current position, hold down the "W" (forward) key and move your mouse to the right of your mouse pad or desk top. Your character will move forward and turn right.
