Master Chief Petty Officer John 117 was a SPARTAN II Super Soldier of the United Nations Space Command and a well-known hero in the Human Covenant War. His assassination of the Prophet of Regret causing the alien race called the Sanghelli or Elites led by Arbiter to be betrayed by the other the Prophets and they joined forces with the humans in their campaign in the Ark. After the Prophets and the parasitic Flood were eradicated, Master Chief and Arbiter were in the frigate Forward Unto Dawn. Only the front half of the frigate took Arbiter went through the Slipspace portal taking him back to Earth, but the back half of the frigate that had Master Chief did not make it. Therefore, Master Chief was presumed dead by the U.N.S.C. after Arbiter transpired the events happened. The super soldier lost in space went into cryo sleep after his artificial intelligence companion Cortana activated a distress beacon.

After years of space drift, Cortana abruptly alerted the super soldier. "Chief! Wake up!" Cortana had Chief thawed out.

"What is it?" the super soldier asked as he woke up.

"We crash landed onto Earth, but the communications system of this ship malfunctioned."

"Then we'll have to find the U.N.S.C. on our own," Master Chief took Cortana's chip and put it into his helmet.

"Take whatever you need. I'm picking movement near the hatch."

Master Chief took a combat knife, hand grenades, a 50 caliber pistol, a 7.62 mm assault rifle, an 8 gauge shotgun, and a rocket launcher. "What is that?" he asked after hearing an explosion.

"Someone used a rocket to break into the ship and … we got company."

A horde of men wearing green and grey vests wielding pistols that were old fashioned. Their heads were covered by ski masks and their goggles were not on. They wore gas masks except one who demanded, "What do you think you're doing here? This is a restricted area."

"Cortana, who are they?" Master Chief asked.

"I don't think they're friendly. I have to set Forward Unto Dawn to self-destruct. Take me to the engine room," Cortana ordered and the ship's alarm was on.

"Stop right there!" the hostile shouted.

Master Chief outran the men due to his superior speed and into the engine room. He plugged Cortana's chip into the control panel and she set the frigate to self-destruct. "Get out of here! Now!" The super soldier unplugged the chip and placed her back into the helmet. After Master Chief fled the engine room, the unknown hostiles arrived only to find the countdown.

"Oh my …" the hostile who did not have the gas mask muttered.

Master Chief dashed out of the ship and found cover when it exploded killing the hostiles inside. "I think we're in Earth but not the Earth we're supposed to be in," Cortana had figured something out.

"Where are we exactly?"

"I got it. We're in Astigos Island, a territory belonging to Lukano that was a country in the Mediterranean coast. The hostiles are soldiers of the Zagorias Federation, a Mediterranean coastal nation."

"What is the Zagorias army doing here?"

"The Zagorias army had invaded this island with the intention of using it as a strategic base to advance into Lukano despite international protests. Though the Lukano Liberation Army resisted, the Zagorias army had seized 80% of the island. It would only be a matter of time before the whole entire nation of Lukano would come under Zagorian control. Now the Zagorian army had captured the Lukano Liberation Army's leader Daniel Winston and several Lukano soldiers. The Zagorian forces negotiated a deal with the Lukano Liberation forces that the Zagorians would return the prisoners in exchange for the Lukano forces' surrender," Cortana revealed what she knew.

"Now we have to fight the Zagorian army," the super soldier faced a horde of Zagorian soldiers.

The soldiers had ski masks, gas masks, and goggles on wielding pistols. The soldiers opened fire at the behemoth; however they were shot in their heads.

"These guys suck," Master Chief muttered as the green soldiers all missed their shots. Two variants of the green soldiers were like the ones that broke into Forward Unto Dawn. Another variant of the green soldiers did not have ski masks and gas masks as their faces along with their spiky brown hair were visible. Thus the green soldiers that had no masks wore goggles only.

Some of the soldiers were white uniform and yellow masks wielding pistols. They were not as accurate as those green soldiers.

"What's with the different colors?" Master Chief asked.

"You might have to find out what they drop. Since you cannot find ammo that the U.N.S.C. use; you should use their weapons," Cortana made an advice. Master Chief came out of his cover and picked up one of the pistols. "It's a 45 caliber M1911. That means we're in 21st century earth."

Master Chief picked up the M1911 ammo dropped by the green soldiers by multiples of five and shotgun shells dropped by yellow soldiers. He moved to another boulder for cover and turned to the hostiles in his right. Before the super soldier returned fire, he took the chance to reload the pistol.

Apart from the two green soldiers that were in standard variants, Master Chief faced a soldier wearing an orange suit, gas mask, and goggles with red-eye tints wielding a light-weight machinegun. Unlike the green soldiers, it took four 45 caliber bullets to waste the orange soldier. "The armor that the orange soldier is wearing is not tough," Cortana commented.

"I never thought armored combat suits can be developed earlier," Master Chief muttered as he gunned down six green soldiers and one of them had no mask with goggles only. He also gunned down another yellow soldier and another armored soldier.

"The armored soldiers are using 5.7mm P90s that are personal defense weapons. The P90 is as light as a submachine gun but has a penetrating force of an assault rifle. The 5.7 mm rounds can penetrate the armor of those armored soldiers," said Cortana and Master Chief took one of the P90s along with the additional 50 rounds dropped by the second armored soldier.

Master Chief advanced and three green soldiers were approaching him. He found cover in another rock and reloaded before gunning them down. Two of the green soldiers were of standard variants and one was not masked with goggles. A yellow soldier along with another standard-variant soldier appeared in front of him. Unlike the green and yellow soldiers, the soldier wore red and fired a shot right at Master Chief. Luckily, the energy shields absorbed the damage. After the super soldier gunned down the two soldiers, he took the shotgun shells and the pistol ammo. A red soldier dropped 30 rounds of pistol ammo after he was killed.

Master Chief pressed on and heard a standard-variant green soldier waving his pistol while shouting, "Go! Go! Go!" Another standard-variant green soldier joined him and the super soldier got to cover in another rock.

The super soldier reloaded his pistol before he gunned down the two soldiers. "I'm picking movement in the sand," Cortana warned.

Out of the sand, two soldiers burst out and rolled in the air. They were wearing white and blue suits with gauntlets that had claws. It took three pistols shots to waste a soldier with claws.

"Use the shotgun if the clawmen gets too close," said Cortana.

Master Chief switched to his shotgun and swept the clawmen. He switched to his pistol to gun down another standard-variant green soldier and a yellow soldier.

When the super soldier moved forward, he saw a horde of soldiers landing via parachutes. "I'm picking additional enemy reinforcements," said Cortana. "Hostiles on your left."

Master Chief took cover in another rock and turned to another horde of standard-variant green soldiers. As he gunned down the soldiers, something destroyed what appeared to be a lighthouse sending the tower rolling right at him. The super soldier took cover and took the chance to reload both his weapons.

After the destroyed tower rolled away, Master Chief pressed forward but another horde of green soldiers barred his way. One of the green soldiers did not have goggles on while one had no gas mask and goggles not on. The super soldier gunned them down before taking down an armored soldier and a yellow soldier.

"Chief, you'll have to pull back. They're bringing in heavier weapons," Cortana warned as an armored soldier accompanied by two soldiers wearing blue uniform and grey helmets wielding bazookas appeared pushing Master Chief backwards. He took cover before another rock at the back and reloaded. "Aim for the oil barrels that are close to them."

Master Chief blew up the explosive barrels blowing the foes up and caused the rock fall. He took the 100 rounds of P90 dropped by the armored soldiers, pistol ammo, shotgun shells, a bazooka, and a rocket dropped by the other bazooka-wielding soldier.

Master Chief climbed over the rubble and took cover in one of the barricades. "You might need to use your P90. The additional enemy reinforcements are arriving via parachutes," Cortana advised. He swatted the paratroopers like they were flies using the P90 before taking on an armored soldier, a bazooka soldier, and a green soldier that had no mask wearing goggles. The super soldier gunned down a yellow soldier and several standard-variant green soldiers before they landed. He then shot down the other paratroopers and reloaded the P90.

Master Chief took all the ammo, shotgun shells, and a rocket before turning left to see a bunker with artillery on top. "Great, they dug trenches," he went into the trenches as he began going left. When moving, the super soldier used his pistol to gun down several standard-variant green soldiers and a bazooka soldier. He then turned right gunning down an armored soldier and another bazooka soldier. A soldier that dressed similar to the bazooka soldier had a tomahawk in his hand. "How lame," Master Chief gunned down the soldier before he could throw the tomahawk. The super soldier gunned down a green soldier that was not masked and wearing goggles only then took down three green soldiers that were standard variants. He also gunned down a yellow soldier and a red soldier.

"Use the ground for cover when you're moving through the trenches," said Cortana. Master Chief picked up shotgun shells and went into the trenches so that the artillery could not hit him like it would if he was in the "no-man's land". He reloaded before gunning down four green soldiers of different variants: one that was standard variant, one that did not have goggles off, one that had no gas mask and goggles not on, and the last one had no masks wearing goggles only. The super soldier reloaded his pistol before going forward.

Master Chief advanced picking up pistol ammo and used part of the corner for cover. He turned to see a blue soldier was about to attack using an old-fashioned flamethrower and it took three 45 caliber bullets to waste a flamethrower-wielding blue soldier. The super soldier then gunned down four standard-variant green soldiers. He reloaded his pistol and went forward.

Master Chief turned left and used another part of the corner for cover. He turned to his right to gun down five green soldiers and a red soldier. One of the green soldiers had no gas mask and goggles not on.

Master Chief pressed forward picking up pistol ammo and was nearly out of the trenches. He turned right to gun down a horde of standard-variant green soldiers, a red soldier, a yellow soldier, an armored soldier, and a bazooka-wielding blue soldier.

Master Chief went into the "no-man's land" and used the sandbags for cover. "Blast the artillery using the bazooka," said Cortana. He fired a rocket at the artillery and took cover from the artillery blast. The super soldier reloaded and fired another rocket that destroyed the artillery. By doing so, the bunker was destroyed along with the soldiers inside the structure. He then took all the ammo, shotgun shells, and rockets dropped by the soldiers had killed.
