Script
A script is used to send commands to the game to allow it to function or do things in a different order. Scripts can be used to customize your controls too doing commands quickly. Scripts are known to be used by script users or how everyone sees them, hackers but that is incorrect. These types of scripts send out codes of info to the players or servers in away to cause them to crash or fail. Easy fixes can be made to stop these from happening.
Modders can use ICARUS scripting with the Behaved tool in order to create scripts for the game, like cutscenes for single player, or complex object movements in either MP or SP.
