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.
