INSTRUCTIONS!
Once the game is installed and started, click on the main character (the one in the main view with the light coloured clothers). Now that the character is selected you can click on the map so he can walk there, double click so he runs, and press the "stance" button so he crouches.
If the enemies see the main character a red cube will start growing on top of their heads, which represents the alert level they are at. Once they are on full alert they will start shooting at the player. You can attack them back by clicking on them and the player will shoot. It takes 4 clicks(shots) to kill an enemy and 10 shots for an enemy to kill you.
