Welcome to the 22nd century. In the game
of Decker, you are a hacker who specializes in breaking into corporate computer
systems, for which you are handsomely paid. Of course, these corporations
don't idly sit by and allow you free run of their systems. The systems are
guarded by Intrusion Countermeasure programs (ICE), which attempt to kick you
out of the system, or possibly even kill you.
The basic equipment of a Decker is the cyberdeck. This wonderful piece of hardware plugs
directly into your brain in order to allow you experience the full virtual
reality world of the matrix. While in the matrix, you use programs to attempt
to bypass the security measures of the corporate systems, or to crash them if
all else fails.
You start out unskilled, unknown, and underequipped, but as you gain experience, you will
increase your skills, hardware, and reputation in order to combat more
difficult and dangerous systems. That is, if you don't get your brain fried
in the process.
