Note: This procedure involves editing a game file; create a backup copy of the 
file before proceeding. Use a text editor to edit the "AiDefault.aai" file in 
the game folder after turning off its "Read Only" file attribute. Scroll down 
until you see the "LIGHT_MACHINE_GUN" entry. Notice that it has as "RATE_OF_FIRE" 
value. You can change the first number only to a lower value. This will speed 
up how fast your weapons fire. Higher numbers make your weapons fire slower. For 
example, set the value from "1000;0" to "25;0". You can do this to machine guns, 
rifles, bazooka, and tanks only. Do not change the second number or anything 
else in this file. Note: This cheat also effects enemy weapons and makes them 
shoot faster.
