With every ending, there is always a new beginning. The ending of Aperture Science wasn't the end of time itself, only the end of one story. There are many more stories to be told, such as yours, the "spartan" so daring to enter this abandoned scientific grave. Ever heard of a "Head Crab" son? The parasite that takes over the the human body whether they like it or not. You call them the flood, but they are the same thing, respectably. You coming down here was a big mistake. Not only will you have to fight the damn "flood", but you have to fight here tooth and nail if she wakes up. Who is "She" you may ask? Well... better leave that one alone till the time comes.
Son, I may be just a personality core, but you need to trust me like a friend. Come on, I know a short cut...

Stay with me if you want to live, I know this place like the back of my hand...
INFORMATION:
This is my personal work that I had done recently, my own infection map that isn't a collaborative project. Welcome to NINE NINE NINE NINE. Back story is you're a Spartan that wound up down here in search of any survivors of this ancient facility and as soon as you came in, no contact could be reached out. Survive against "the flood" as you attempt to escape or prey that they will leave you alone long enough so you can make an exit.
Plays standard infection and a 2V2 variant is planned. use everything in the map to your advantage, and watch out for any hidden traps and eastereggs as a homage to the original series "Portal". Thanks everyone, and know that this map will be constantly supported. Let me know if anything stands out to you as needing fixed (aside from the giant hole in the ceiling ).
Love you all, this is MJ Rookie, signing off.
