**Core concept: CoreWars**
|
|
|
|
Core War is a 1984 programming game created by D. G. Jones and A. K. Dewdney in which two or more battle programs (called "warriors") compete for control of a virtual computer. These battle programs are written in an abstract assembly language called Redcode. - (Kagi summary)
|
|
|
|
Looked up what CoreWars is, and it is essentially a 1v1 game with players controlled by its own syntax.
|
|
|
|
The only player that will always lose will be one who commits suicide; which is done using `DAT 0,0`.
|
|
|
|
```zsh
|
|
nc saturn.picoctf.net 51554
|
|
Submit your warrior: (enter 'end' when done)
|
|
|
|
DAT 0, 0
|
|
DAT 0, 0
|
|
|
|
|
|
end
|
|
end
|
|
Warrior1:
|
|
DAT 0, 0
|
|
|
|
end
|
