P8-10

Hint
"Get the alien and his holograph to his ship!"

Solution

 * Kill the Secret Agents with a Blob/Ooze/Death.
 * Take out the Security Cameras.
 * You can now free the Alien. It's fine if he ends up at the lower level and not at his ship.
 * You do have to fly up with his Holograph to the upper level though.
