|Using the Hacker PDA|
- "Upload the virus."
- — Keegan in "Federation Day"
After the Ghosts infiltrate the Federation skyscraper in Caracas, they enter a data archives room. Logan then uses the Hacker PDA to send a virus into the Federation's system. Logan can upload the virus at once, in which case he will barely complete the process before several guards pass him and Keegan. Alternatively, he can upload a part of it, then interrupt it in order to hide from the passing guards (or even kill them) and resume the upload afterwards.
