Hint: Opening the door in the basement when chasing van Cleef:
When in the basement, you will find a health pack and below it a
wooden plank. Use your night vision goggles to see a green line that
connects to a door further up. Around that bend is a patrolling
guard. Kill the guard and pick him up. Walk over to the plank and
place the body there. The door that the green line you saw earlier
connects to is now open.
