What is Core War?
Core War is a game played by two or more programs (and vicariously by their authors) written in an assembly language called Redcode and run in a virtual computer called MARS (for Memory Array Redcode Simulator). The object of the game is to cause all processes of the opposing program to terminate, leaving your program in sole posession of the machine. There are Core War systems available for most computer platforms. Redcode has been standardized by the ICWS, and is therefore transportable between all standard Core War systems.
