He got on a spaceship and it was a good ride but then the aliens attacked and everyone was screaming and there was smoke so dark master cheif got his gun and said "lets do this" and he jumped out of the ship towards the planet, and it got super hot but he had is suit on. He hit the planet super hard and u thought maby he is dead but then he got up and said "ok time to do the mission" which was super secret which is why they gave it to him.
He went to the ennemy base and there were aliens so he used his suit to zoom in and look carefully to find a good strategy for sneaking inside. So he sneaks inside and then a alein spotted him even tho he is careful and says "HEY YOU STOP UR NOT SUPOSED TO BE HERE" and dark master cheif smirked and said "sory cant here ya" and shot the alien with a shotgun.
This was all well and good but now the aliens new there is an intruder so he had to be fast and complete the mission. He got to the main bosses office and the boss said "SO DARK MASTER CHEIF U HAVE COME TOO KILL ME" and dark master cheif said "YES" and the alien boss said "OK LETS DO THIS" and there was a big battle but dark master cheif did not have time for the battle because the ennemy forces were come soon so he took a plasma grenade and stuck it to the boss and then throw the boss out the door to the other ennemys and they saw the plasma grenade and the one in front said "OH SH" but he couldnt finish because the grenade blew up. dark master cheif set the bomb to explode quickly and then run out of there super fast like a cheeta and he got outside but between him and the escape ship was aleins so he said "lets do this" and charge in
he used lots of weapons and killed lots of aleins but then his shield ran out and just then the bomb blew up and all of the aleins were distracted so he ran even faster to the escape ship and they took off and escape. as they flew away thye saw the blowing up base and dark master chief said like a joke "some on should fix that, serosly" and the ppl in the ship laughed.
After he completed the mission was completed they said "good job dark master cheif unfortunately you are a secret illegal clone so we cant say to anyone what you did but this makes the fights on the HALOs possible" and it wasnt written in any history book but they remembered him and he lived to fight on in secret to help the cause and his original master cheif clone-brother.
THE END
