+**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
+
+Warning:
+        Missing ';assert'. Warrior may not work with the current setting
+Number of warnings: 1
+
+Rounds: 100
+Warrior 1 wins: 0
+Warrior 2 wins: 100
+Ties: 0
