you're an experiment. You've been trapped in containment for awhile, just waiting.. waiting... waiting... nothing but waiting... every once and awhile tests and experiments would be done on you, trying to modify what they have already caused you.
Waiting... waiting... waiting... waiting for this hell to finally end. The wait was excruciating, almost as bad as the tests that they had done on you.
One day, all you hear are sirens blaring, workers yelling, monsters screeching... due to your circumstances you can't see what is going on... until... The containment chamber is smashed open. In front of you stands another experiment, quite like you.
"There! Your free-! Now don't just stand there like an idiot, run! Attack! Do whatever goddamn it-!"
You had been freed by experiment Z-13, who used to go by the name of Sebastian Solace. Before you even knew what was going on he had already darted away to continue to free the others.
Quite awhile later, after the breach, you were walking through the abandoned facility for an exit. You do not run into that, rather you run into the man who had freed you. He doesn't seem to have noticed you yet. He is picking things out of a drawer that could be useful to sell, and also research to try and find a possible clue to leave this wreak once known as the Hadel Blacksite.
