Forge World Creepypasta

Some of you have probably heard of the Ghosts of Halo. Appearing in some of the Halo games these player like entities could preform very difficult jumps with ease, teleport randomly across the map, spawn random weapons, have perfect accuracy, and could kill players instantly. But what i experienced in Halo: Reach was not a ghost of Halo, I don't know what it was.
The event
It was over two months ago yet I remember everything vividly, I started up Halo: Reach on the Xbox 360 with a friend of mine who won't be named. We got on Forge World to make an infection map. There was a barely noticeable change of color for the map, everything was slightly darker and more grayish then usual. Yet the Game was in perfect condition and we didn't have any of those things that affect the color of the map. I didn't mention it to my friend and we continued to build the map. About a quarter of the way done my friend briefly left to eat dinner, so it was just me for the time being. I looked across the map looking at our progress, when I noticed a spartan standing on the island at the center of forge world. I spawned in a sniper rifle and zoomed in to get a look at the mysterious figure. It had red armor, a black visor, and was carrying a pistol. It looked right up at me, making no turning animation and just stared. After around 30 seconds it vanished. My friend came back shortly after and I told him about what happened. I felt creeped out but not too scared and my friend seemed to feel the same way. We continued to build the map but around 10 minutes later we saw a Banshee flying towards us. It landed on top of one of our buildings but no driver came out. We decided to call it a night and went offline, nothing that creepy yet.
The Next Day
The next day my friend said that he didn't know if he was going to be on but told me to continue building the map anyway. As i got on I noticed that the change in color had gotten more prominent. All of our weapons had been scattered across the map and one of our buildings was on fire. This was incredibly strange and freaky because there is no possible way to spawn fire in Halo Reach's forge mode. I tried to see if the fire was selectable but it wasn't, so I had to go through the incredibly frustrating task of moving every part of the building away from the flames. Once I was finished I took a bathroom brake. As I finished washing my hands I heard the sound of a sniper shot from the game, I had been killed but when I checked the player list I was the only one there. Now I was truly freaked out. I looked up towards the large canyon where the map hemorrhage seen in multiplayer is located. I saw the same red armored spartan staring down at me with a focus rifle. I spawned in a sniper rifle like I did before and fired 3 shots at the spartan. The bullets ricocheted off the figure and it vanished as I fired a fourth shot. The assassination animation played yet there was no spartan behind me. I respawned at the island but before I could do anything the screen went black as if a cutscene was about to play. A demonic kind of mumbling began as the black screen ended and the spartan appeared before me. I tried to fire my weapon or move away but couldn't do anything, the spartan just stared at me. All of a suddn the demonic mumbling turned to screaming causing me to throw my controller across the room. The Spartans helmet melted off its face revealing a face with black empty sockets for eyes, no nose, and a mouth full of razor sharp teeth. The face was extremely lifelike compared to the rest of the games graphics. The thing lunged at my character almost causing me to run out of the room. I watched at the thing mutilated my spartan tearing off his limbs and sending bits of my armor everywhere. The demonic screaming got to a point where I thought I would lose my hearing, yet it subsided a few seconds later. I got another look at the creature staring right at me through the tv, staring right into my soul. It's mouth locked in a smile with its razor sharp teeth now covered in blood and bits of armor. The screen then slowly faded to black and brought me back to the main menu.
Aftermath
I sat there completely dumbfounded just staring at the menu, I moved to look at my spartan only to see nothing. He was just gone. Out of curiosity I selected forge and went to select a map. Forge world was there yet all my maps where gone. I selected Forge world and the game crashed. When I selected forge again Forge world had completely vanished. I got a text from my friend, he asked how much progress I made on the map. I didn't want to tell him what happened so I said that my files where corrupted and that I lost the map. He was angry but quickly got over it. I deleted Halo: Reach and didn't play my Xbox for a week. I eventually got back on the Xbox and saw that I had got a message from a blank profile. It was just random numbers and letters with the only noticeable word being death. My friend and I continue to play together on the Xbox, yet I still don't know what in gods name that thing was that ruined Halo: Reach for me.
