After two days of rest, the Doom Slayer departed for the strange wall that was located to the south in the Phantom. He quickly swerved out of the way, narrowingly missing an Enforcer that was currently on patrol at the time. The Forerunner machine turned around and promptly gave chase after the purple alien ship. Firing it's missles and particle repeating cannons at the strange alien vessel. Doomguy turned on the auto turrets to get rid of this pesky machine, grabbed the throttle, and pushed it as far it can go before ripping it out.
"Warning! Engine Overhea-" The alarm blared which annoyed the Doom Slayer to a point where he smashed it with his fist.
He noticed a large entrance coming up ahead. He grabbed for the controls and braced for impact. Crashing the Phantom into the open entrance of the Sentinel Wall. He kicked out the shuttle door aside, dusting off some debris that was on his armor. He inspected his equipment for a few minutes while making a few adjustments to his weapons and the demonic runes he collected back on Mars. He could hear the sound of afterburners outside, knowing that this machine would not give up so easily and grabbed for cover behind a pillar. He stayed behind in the dark for a little longer, observing the mysterious large machine hover cautiously into the area.
"A plasma charge mod is best for this. Fire a one stun charge to disable its shields, then destroy it with a siege charge from my Gauss Cannon." Doomguy silently thought to himself as he studied the machine's offensive and defensive capabilities from behind a large pillar with blue lights on its sides.
He fired a plasma charge at the machine, disabling it's shields and quickly fired one charged shot from his Gauss Cannon. Destroying the Enforcer in one shot. Watching it crash into the fog below. He glanced back at the strange blue lights on the pillar. Studying the strange Forerunner symbols on it. Giving it a curious touch and promptly stepping back. Watching the pillar open up revealing some kind of vent below. Without further a do, he jumped into the vent. Falling down into the deep section of the Sentinel wall.
"What is this place?" He wondered while looking around the twisted hallway. He continued onward and about halfway... one Sentinel replicator opened up, producing a golden Sentinel. Doom Slayer raised his plasma rifle at the Forerunner machine, then held back. As he got a gut feeling that these Sentinels on this ring maybe very different from Sparks's. Or might not know about the destruction of Installation 04. He followed the Sentinel as it opened many doors and pillars for him to enter. Doomguy followed the Sentinel through a couple more chambers. Dropping down into another that lead directly into a large chamber with two Enforcers guarding the massive door behind them.
The Doom Slayer immediatly recived fire from both Enforcers. Dropping down onto the platform, he returned fire with his BFG-9000. Wiping out both Enforcers in one shot and blew away the smoke that steamed out from the barrel. He starred at the closed and burned out sentinel replicators that were on the wall. Wondering why some were burned out and some were not before moving onward to disable the couplings that is holding the platform he is standing on. The Doom Slayer carefully placed his hand on the light blue hologram as before. Hearing the connecting pillar rise up one by one into the ceiling. Turning around to see a hologram console appear in front of him. He carefully placed his hand onto the console. Deactivating the wall energy barrier, giving him complete access to the Quaratine Zone.
Doom Slayer rode the platform toward the entrance of the Quaratine Zone. Where he was immediaetly assaulted by flood Combat forms from eons past. Blasting them away with a few blasts from his super shotgun before finishing off the last one with a glory kill. Ripping the arm out from it's socket, bashing the deformed head back with it. He heard the sputtering from behind and turned with lightning speed, aiming his super shotgun at the golden sentinel which hovered in front of him.
"Greetings Reclaimer. I've been watching you since you entered this facility. Knowing that you've destroyed a few of our Enforcers, I'll dismiss it so we can focus on our main situation at hand. Please follow me." The Golden Sentinel explained to the Doom Slayer. Showing him a door with a long blue lit hallway.
The Doom Slayer lowered his super shotgun, replying; "I'm listening." while he followed the Sentinel through the facility.
"Excellent. The Flood has control over many places within the Quaratine Zone. These are areas that we cannot access due to their presence. I've sent in many Enforcers to sterialize the ares but with no success. To destroy them you need to destroy their infection nests located in the Flood Containment Facility code named 'Cold Storage'. Cleansing this area will grant you complete access to the Library. The armory is this way. Please follow me." The Golden Sentinel explained, flying into another hallway. Showing the Doom Slayer an large room that held many different kinds of Forerunner, Covenant, and suprisingly some Human weapons as well.
He found one that caught his attention and reached upward, ripping it off from the wall. Watching the weapon split apart as it loaded it's hardlight power cell into the chamber. "Cool. Very cool." Doomguy said, placing the Z-390 Incineration Cannon into his weapon pack.
"Take many supplies as you need. I'll get the door opened that will lead you to the next sector. Touch the interface and I'll transfer full administration access for you to use." The Golden Sentinel spoke in a robotic voice.
The Doom Slayer walked up to the interface, touching it only to recieve a massive electrical shock. As the information was transfered through his armored fist in a blue electric light that sparked before him. He looked at his hand for a few seconds, feeling the warm pins and needles underneath his armor, then shook it a few times to relieve it as he walked up to the Golden Sentinel who is patienly waiting by one lone opened door.
"Good luck, Reclaimer."
Once the Doom Slayer entered inside the long blue lit hallway. He heard the door behind him quickly close with a familiar squealling sound. A sound that reminded him of a sixteen bit past that felt like a dream. He tuned his suit radio to FM 87.9 to hear Jeff's stoner doom metal playlist starting on a new song. Locked and loaded along with good music playing, Doomguy opened up another piston and jumped into the deep hole. Slamming his fist into a fresh new corpse of a Flood Combat form and blasting a few more away with his super shotgun. He walked up to the Flood nest, inspecting it from the ground up to find a juicy object to pull. Pulling the strange object out to hear the loud shreaking screams of awaking Flood rising up from the dead seconds later. He pulled out his chainsaw, pulling its plug a few times, hearing the good reving sound and pulled it once more to hear the fresh sound of its chuckling engine. The Flood shreaked and screamed, rushing towards the noise. Only to be evicerated by the Doom Slayer's chainsaw left and right. Splattering the walls with green blood and littering the metal floor with severed appendages as the Doom Slayer pushed through them, reaching a maintence elevator that took him directly to the Flood Containment Facility code named "Cold Storage".
Deep, deep down in the bowls of the Library. The Gravemind growled as he watched the unknown green juggernaut systematically wiping out his Flood minions and nests throughout the Flood Containment Facility from a hologram provided by his control of Monitor 2401 Penitent Tangent.
"Current scans indicate that this soldier is a Reclaimer. He must be trying to gain access to the Index. Traveling through the Flood Containment Facility is the quickest route, but extremely dangerous as the Flood controls most of that area. Though, it would be interesting to observe this Reclaimer survive wearing nothing but an Class IV armor suit."
"He will not survive." The Gravemind growled then noticed strange alien ships arriving on another holoscreen. "Hmmm... Although, he might be very useful tool for an interesting problem that arrived.
