You'll need the Sniper rifle to see this one. Just after leaving the large room at the start of the mission, Look out through the large window on the left. Zoom in and you should see the cheese sitting out on the ocean floor. 

Leaderboard Crown

Can't Touch This - To earn this Crown, you must complete the first objective (Reactivate the teleportals), without taking any damage, on Perfect Agent difficulty. This Crown can be quite challenging to earn, as most of the enemies leading up to the teleportal possess Shotguns, which can damage you from a suprising distance on Perfect Agent. The best advice is to take your time on this one. Make good use of your Falcon 2 (Scoped), and let Elvis kill the guards in the first few rooms with his FarSight. On the way, you will encounter guards with CMP-150s, as well as a few Mr. Blondes, who may pose even more danger if you are not careful. 


To unlock the "Jo Shield Cheat, beat the mission on any difficulty. This Cheat, when activated, allows you to start any mission with a Shield. To unlock the "FarSight Cheat, beat the mission in under 7:27 on Perfect Agent difficulty. This Cheat, when activated, allows you to start any mission with a FarSight XR-20.
