Irriversible

You are a hacker who came to DIU as a spy from [****], you find a low-level agent's computer, you type in the password for the computer and the password for the Log Entries that the agent wrote and as you hoped, you find a lot of information on future and past missions. But what you see with those are mind-blowing.
