This level is easy. The only problem you have is when you panic and mess it up. If you panic then you will die. The cheat is very easy to get on this level.
Start off by exiting the cutscreen when Daniel says: 'De Vries.' That way the guards are in good positions. Strafe round guard one and enter the tunnel. Punch the FBI guard as you exit, if you don't then you will have tonnes of magnum guards to deal with. Pop into the tunnel and punch the guard from behind. Whip out your Falcon II and shoot the FBI guard on the phone. reload, then push the dumpster near the explosive barrels. Shoot the barrels and collect the bombspy.
Run past all the guards with your tracker bug out. Lobb it onto the limo as you Strafe past it. OBJECTIVE COMPLETE.
Wait JUST before the gap in the wall and unleash the bombspy. Guide it to the centre of the 4 guards near the elevator and detonate to complete an OBJECTIVE.
Drop int the sewers and collect the equipment. The next OBJECTIVE is now complete!
Run past all the guards with your remote mine selected towards the area with the ladders. Lobb the mine precariously towards the door and pray it lands on it to complete the next OBJECTIVE.
Now its a mad dash to the finish. Get your CMP150 out and mow down any guards in your way as you run towards the elevator. Enter the elevator to complete the next OBJECTIVE.
Now, unless you slowed down you should have a time of 0:50 seconds. You should certainly get the Psychosis gun cheat.
