A Covenant Phantom is seen flying over Mombasa and activating it's lights and being to search for something. Down blow we see Y/n, Rookie, Simmons and Donut sneaking through the city and avoiding the Covenant forces as best they can.

They hide within the darkness as they avoid Covenant patrols or Phantoms flying around. They keep sneaking through the city and after for some while they arrived at the location which was Mombasa's train station as they look around only to find a tub that is use to fill up the wounds of soldiers.

Rookie picks it up and shake on it only to see that it is empty so he drops it. While Y/n looks at the close gate to the trains while he turn to see Simmons working on Lopez head.

Y/n: How is he doing?

Simmons: Kinda hard. It seems he was blown up and his head landed at the other side.

Donut: So Sarge and the others were there and now they ended up here?

Y/n: Maybe and the train station is the only way out of the city.

Donut: So they escaped?

Watcher: I don't think so. The trains inside we bursted meaning there is no way they could have gotten out unless they found one that is working. Even if they do the tracks are destroyed.

Simmons: So they might be dead?

Y/n: I don't believe that for a second. We'll find them when we will not gi-

???: (radio) Can anyone hear me? Does anyone copy this is Dare is anyone out there?

Y/n: Dare?!

Simmons: Wait I thought Dare was dead?

Donut: Whose Dare?

Y/n: Dare this is Spartan-453 we hear you loud and clear. What is your location over?

The radio goes to static which Y/n ask Watcher.

Y/n: Can you pin point her location?

Watcher: Let me see. Oh.....Well you may not believe this but she is below the city.

Donut: Like underneath us? Why should she be underneath us?

Y/n: One way to find out. Rookie let's go.

Rookie nodes and the four move on and soon arrives at a elevator that takes them underneath the city. There was no elevator so one by one they leap across and grab the elevator cable and slide down.

Y/n was last as he turn back and after seeing the ghost is clear he too leap over ans slide begin his decent.

(Short while later)

Donut and Simmons crash on top of each other while Rookie and Y/n safely land on their feet and aim their weapons only to see nothing.

Y/n: Where to now Watcher?

Watcher: According to her singal she is at sub-level 9.

Simmons: What level are we in?

They turn to the wall and sees they are in sub-level 7.

Y/n: Come on let's make it there.

Simmons: (sigh) I can't believe I have to say this but I just want to take a break.

Donut: Come on Simmons we need to be together in hopes to survive so let's get up and let's go.

Simmons sighs and they begin their journey. They walk through a door that takes them to a long tunnel which they begin to walk down. When they turn a corner they quickly hide when they see Covenant forces blocking their way.

Y/n takes aim of his carbin but Rookie stops him and points to a door near them they can take as a short cut. Y/n nodes and they go through and once at the other side they keep on walking.

They continue going deeper and deeper of this mysterious facility as they avoid the Covenant forces as best they can. After a while of walking they hear gunshots which they stop and realise it is from a shotgun.

Simmons: Is that sarge?

Y/n: Whoever might be needs our help, come on.

They follow the shots and soon they arrive to a Mombasa police officer shooting the grunts but when a brute came out the brute slaps his shotgun away and force him on the ground.

He aimed his spiker at him but Y/n fire his carbin while rushing towards him. The brute growls ans tries to swing the blade of his spiker at him but he slides beneath it and pulled out his combat knife and land a few stabs.

Then Rookie came over to finish the job and the brute drops dead. Y/n turn to the officer and helps him up.

Mombasa Police officer: A Spartan. Thank god to be seeing you.

Y/n: What are you doing here officer?

Mombasa Police Officer: I have orders to be here.

Y/n: By Dare?

Mombasa Police Officer: No but i could use some help.

Y/n: Sure thing.

The officer news and he turns and leaves as Y/n had a bad feeling about this officer but they follow him. They make their journey through all awhile Donut and Simmons stare at the Rookie as Donut whispers to Simmons.

Donut: (whisper) I've never heard Rookie ever talked. He's completely silent.

Simmons: (whisper) Yeah no kidding and he's different to other ODST. They are more like elite versions of the marines but Rookie here acts like somewhat of a Spartan.

Donut: (whisper) You think he's secretly a Spartan?

Simmons: (whisper) Don't be stupid Donut. He may have gotten some training or something. Either way let's just shut up or he may hear us.

Rookie can hear them but doesn't say anything. A door opens in front of them but when they step in it was freezing. They keep on walking and soon come across a iced covered up door as the officer said.

Mombasa Police Officer: Wait here. I need to do something.

Y/n: Why can't we not come with you?

Mombasa Police officer: Sorry that's classified. Just wait here.

The officer goes inside and once inside they were confused on what he said.

Simmoms: "Classified?" Isn't he just an officer? Why would he say it is Classified?

Donut: Hm that is strange.

Y/n has a bad feeling and he turn to Rookie and he node and he node back.

Y/n: Simmons, Donut wait here. We're gonna confront him.

The two node and Rookie and Y/n head in and once inside they find the officer at the controls and he turn and see them.

Mombasa Police Officer: What are you two doing here?! I told you to wait outside!

Y/n: Why would an officer tell us what to do? What are you doing?

Mombasa Police Officer: It's classified!

Y/n: Bullshit! Move out of way.

Then the officer lifted his shotgun at them which they immediately raised their weapons at him and the two have a stand off.

Y/n: Lower your gun officer. That is an order.

Mombasa Police Officer: I can't do that Spartan. I'm sorry....you know too much.

He then aim his shotgun at Rookie but Y/n covers him with his armor as the shot breaks his shield and then he throws his knife which impaled him in the arm.

Rookie rushes up and punches him in the face and knocking him out. Once the officer is down Watcher gets access to the controls and looks through to the files.

Watcher: Listen to this. It seems that this officer was deleting some important files from Dr Endesha which is that frozen body next to me.

They see the body against the wall. Y/n turn to the unconscious officer and tie him up. Once they did that he begins to wake up and sees the two looking down at them.

Y/n: Who order you to delete files from Dr Endesha?

Corrupt Police Officer: It was Kinsler. He order me to make sure the doc is dead and no one knows about it.

Y/n: Why? What's down here that Kinsler wants to keep in secret?

Corrupt Police Officer: Wish I know but the Covenant is sure looking for it. Whatever it might be down here.....it knows.

Y/n: Who else knows?

Corrupt Police Officer: The superintendent. It knows what the Covenant is looking for and it's keeping it safe from them or anyone. There that's all I know. Now what? What are you gonna do with me?

Rookie and Y/n look at each other and to the officer and then we cut to Simmons and Donut waiting for them and when they came out the Simmons ask.

Simmons: Where's the officer?

Y/n: Taking care of. Let's keep moving.

They agree and while leave the door the two came through closes and we see a crops of the officer as the door closes shut.

(Hours later)

After a while of walking deeper and deeper to the facility they finally reach Sub-level 9 and the singal is strong. They walk down a small hallway and arrive at a door.

Y/n knocks on the door and waits as they turn back so they are sure they are clear. Then the door open and Y/n turn only to be met with Sarge aiming his shotgun at him along with Dare.

Sarge: Y/n?

Y/n: Sarge!

Sarge: Well it's good to see you not dead. It's only unfortunate that your not grif otherwise I would have kill you.

Grif: I heard that!

Then Grif came around the corner and walks up to them as Dare lower her pistol.

Dare: Well this is a surprise. I was suspected someone bit enver suspected a Spartan. What's your name?

Y/n: Names Y/n. This is Simmons, Donut and Rookie. The robot head on Simmons waist is Lopez.

Sarge: Ah there you are! We have been looking for you. Where did you find him?

Simmons: Found his head near a destroyed ONI base.

Donut: You should have seen it. There were huge flames in was really nice.

Grif: Good thing we were not there.

Y/n: Well where have you two been and is Cali and Remington with you?

Dare: Yeah. Come on I'll explain to you everything.

They walk inside and once inside Dare shuts the door a d they turn a corner to see injured ODST and some standing either near a door or window only to turn to see Y/n.

Y/n look around and then he sees Cali and Remington there so he walks over and soon they turn and noticed him which they came over and hugged him.

They stop and Cali gently punch his shoulder.

Cali: (smirk) I knew you won't be killed easily.

Y/n: (smile) Yeah. Good to see you all okay.

Remington: Same.

Dare came over to them which Y/n turns to her and ask her.

Y/n: Time to get you all out of here.

Dare: Not yet. There is a mission that I need your help with.

Y/n: That being?

Dare points to a window to a massive open space except in the middle there is a bridge that is connected to a ONI building which Dare explains.

Dare: That's where the Superintendent is at. We need to get the Superintendent out of Mombasa before the Covenant gets to it first.

While looking out of the window above the window we see a drone poking it's head through the window and then flies away. Soon it arrives to alarge room with walkways while above it are hives that contain drones inside as they wait for their prey to come by so they can ambush and kill them.
