corewar

What is Corewar?

• Corewar is a very peculiar game. It’s about bringing “players” together around a “virtual machine”, which will load some “champions” who will fight against one an-other with the support of “processes”, with the objective being for these championsto stay “alive”.

• The processes are executed sequentially within the same virtual machine and mem-ory space. They can therefore, among other things, write and rewrite on top ofeach others so to corrupt one another, force the others to execute instructions thatcan damage them, try to rewrite on the go the coding equivalent of aCôtes duRhône 1982(that is one delicious French wine!), etc...

• The game ends when all the processes are dead.
  The winner is the last playerreported to be “alive”.
