Agents 3 and 4 hadn't been able to catch a break. They had been fighting Octarian forces all day on their mission to recover a captured Zapfish that was discovered being transported by Octarian forces to an unknown location in a recent scouting mission. The Cap'n wasn't entirely sure what they were using the Zapfish for but he had told them it must be something evil.

"Threeee let's take a break. Pleeease?" Agent 4 whined. "We've been walking and fighting all day" He said.

Agent 3 stopped and sighed while putting her hand over her face and pulling down. She then took a look around. They were currently walking down a path going along the face of a cliff on their way to the valley below them. A little farther down the path she noticed an indentation in the cliff side with w large rock jutting up from the ground that provided decent cover. "Fine, we can take a short break up ahead. But then is back to the task at hand" she told him while motioning towards the rock she saw. Then they both started walking

"Finally!" Agent 4 exclaimed in relief as they finally reached the cover. He then proceeded to fall to the ground in an over dramatic manner.

Agent 3 scoffed at the display. 'He always acts so childish' she thought to herself. Granted, he still was only 15, so he still technically was a child but he could at least act his age on a mission as dangerous as this. She continued to watch him take off his shoes and start rubbing his feet while groaning.

Agent 3 had seen enough of 4's antics and needed a distraction. "I'm going to keep watch for enemy movement. You stay here" she declared while pointing at him. She then promptly turned around and started walking farther down the Cliffside towards a good vantage point.

Agent 3 stood at her post for probably 10 minutes with no sign of enemy activity. She took in a deep breath and let it out slowly. Maybe Agent 4 was right, this little break from walking was pretty nice. Speaking of Agent 4, Agent 3 decided it was probably time to continue walking. She was just about to start heading back to Agent 4's location when a gleam caught her attention from the valley below. She quickly pulled up her binoculars and looked down at the source of the gleam. When she did so what she saw made her freeze.

Crouched down in the middle of the valley was an Octoling. But the Octoling herself was not what made her freeze. She had battled many Octoling soldiers in her time as an agent and taken them out without a problem. No what make her freeze was the object that this Octoling was currently resting on a rock as a stabilizer and aiming right at Agent 3.

Agent 3 hardly had enough time to duck down before a barrage of purple ink shot directly through the air where her head was at only moments before and collided with the cliff face behind her. If she hadn't ducked when she had then she would be dead right now. She didn't have time to get Agent 4 for back up as the Octoling Sniper was already charging up another shot. With not many options at her disposal Agent 3 jumped down into the valley below.

Agent 3 could feel the wind as she plummeted into the valley below. The ground was quickly approaching and Agent 3 was praying that her loosely made plan worked. If it didn't work, well then this was going to hurt. A Lot. The fall would not kill her but the speed she was falling at meant that her body would most likely take on most of the impact. She really hoped her plan for landing softly worked. Or else the Octoling would most certainly have time to take her out before she would be able to stand again.

Agent 3 watched as the ground got closer with nervous anticipation. She quickly tightened her grip of her dualies as she fell. Just as she was about to hit the ground she shot a puddle of green ink onto the ground below and turned into her squid form as she hit the puddle with a big splash.

Once the ink settled, Agent 3 hopped out of the ink and reverted back to her inkling form. She then let out a small chuckle, relieved that her idea had worked. 'I'm so glad that plan actually worked' she though.

Her relief was short lived however as a jet of purple ink flew past her head, missing her by only mere centimeters. She quickly dodge rolled behind a rock and started scoping the best path to take down the Octoling. The Octoling was in the middle of the valley and there where various trees and rocks that would provide enough cover for her to get in range to hit her with her Hero Dualies. After she had formulated a good path, she took a deep breath and started to run.

Meanwhile Agent 4 groggily awoken from a light nap. He gently rubbed the drowsiness from his eyes and stretched his arm muscles. He took a look around him and saw no signs of Agent 3. He checked the time and found that almost 17 minutes had passed. 'Three should have come back by now' he thought to himself worried. He pulled himself off the ground and walked to the entrance of the alcove.

He was greeted to the sound of gunfire from the valley below him. The entire area was full of green and purple ink. However he saw no signs of Agent 3 or any Octarian forces she could be fighting. He scanned the area for any indication of movement. Then he saw them. On the far side of the valley, Three had an Octarian soldier cornered and surrounded by a ring of ink. Just as she was about to finish the Octoling off there was a low rumble the resonated through the valley. Soon after the entire ground started to shake violently. Agent 4 also felt the quake and crouched down to avoid falling over.

Soon after he had gotten low to the ground he heard a cracking noise from behind and above. He snapped his head around at the sound and his pupils shrunk to pin pricks. The earthquake had caused a landslide that was heading straight at where he was currently laying. If he stayed still he was going to be buried alive. Without thinking he shot a path of ink to the side and dove in, narrowly avoiding the sharp rocks as they flew past him.

Agent 4 was not the only one who experienced troubles due to the earthquake, Agent 3 had kept her eyes on the Octoling sniper during the quake so that she couldn't use it as a distraction and escape for backup. The Octoling on the other hand was in a panic. She had already taken two hits from the Inkling Agent once in the thigh and once in her left shoulder, which had caused her to drop her only weapon. She could feel the foreign ink slowly sapping away her strength and leaving burns on her skin as it dripped down. If she were to take two more hits then she would without a doubt be dead. Then the earthquake had started, at first the Octoling had felt relief, thinking the quake might save her by causing a distraction and allow her to escape with her life. Unfortunately, that relief was short lived when she realized the inkling hardly seemed deterred by the chaos around them. Then she heard a sound make her stomach drop.

*Crack*

In between the Octoling and Agent 3 a large crack formed on the ground. This occurrence was enough to cause both parties to freeze and stare at the crack.

*Snap*

The break in the ground spider webbed out from the center in a circular area. Both Agent 3 and the Octoling soldier were within the radius of said circle. Both of them looked at each other, Agent 3 finally slipping up and showing slight signs of fear on her face. The Octoling on the other hand had the look of absolute terror and despair on her face. This was it, this was how she was going to die. Not by the hands of an inkling soldier, but being swallowed by the very earth that her kind was forced to dwell in. Her only happy thought was that the same fate would be shared by her enemy. This thought gave her some comfort but it did little to stop her overall fear.

Then the earth went still. Nobody moved for a few precious seconds. The two of them continued to look at each other. Three's fear quickly diminished as soon as the earth stopped shaking. Realizing she was showing weakness with her face she hardened her expression. She raised her dualies back to the Octoling to put her out of her misery. While doing so she unknowingly shifted her weight forwards.

*Crack*

The shift in weight caused the earth to give way completely and both Inkling and Octoling disappeared into the depths of the earth.

As soon as the earth had stopped shaking, Agent 4 had popped his head out of his ink puddle. When he decided that it was safe he fully emerged from his ink. He then ran to the ledge in search of Agent 3. He saw that she was okay, although there was an extremely worrisome crack that surrounded both Three and the Octarian soldier. If he didn't know any better he would say the ground looked like it was about to give way. His fear was confirmed when Three stepped forwards slightly and a loud cracking sound echoed throughout the valley. At the same time Agent 4 saw the ground disappear into the earth.

"THREE!" he called out as she disappeared.

His call was never heard by its intended recipient however as his call was drowned out by Agent 3's own screams in addition to the Octoling's as they fell into the depths.

Agent 4 was about to contact Cap'n Cuttlefish to inform him of the emergency when he realized that Three had the communicator on her. He was unable to check the hole himself as the landslide had blocked the way to the valley and he was not brave enough to jump of the cliff. Making up his mind, he decided the best course of action would be to run and get backup. With that he started running back in the direction of the kettle.

And so that concludes the first chapter. Now as much as I love reading, my skills as a writer are in my opinion mediocre. Most likely, this chapter is full of run on sentences. But anyways back to this story. The idea for this story came to me after I was watching video of streamer playing Splatoon 2, I had also recently listened to Portal 2's end credit song because I'm a big fan of the series. But this also got me thinking. If G.L.a.D.O.S supposedly is self-sustaining and will "Live Forever" then 12,000 years should be nothing. Her facility is underground so the flood would not affect her at all. She has no knowledge of the current abilities of the new species on the surface besides the fact that they are intelligent enough to form civilizations and speak their own language. This led me to the idea to combine the two series and have G.L.a.D.O.S test the new dominate creatures of the planet, in the name of science of course. Some things going forwards, I know that Half-Life is technically apart of Portal's universe, but I do not have enough knowledge of the Half-Life games to reliably add it into the story. They may be mentioned later in the story but for now they won't show up. Also I am still looking for names of the characters. I am going to be using Agent names until I decide on actual names.
