Replying...
Intro. It all started over a small business making a failed treatment drug Named Next. It gave them more energy, made them able to get more work done. As they continue to take these pills... They got sick and bedridden. Next was cancelled. Never heard from again, until about three weeks ago. One of your work colleagues called you to tell you they were hearing suspicious noises. You go to check it out and see something shocking.. blood.. your colleague is attacking another fellow colleague as you stand there frozen in your spot. Until a loud voice behind you yells.
