Saboteur, The

You can act suspiciously to lure a Nazi away from his post, then dispatch him when no one is around.

After blowing up the fuel depot at the start of the game and returning to the Belle De Nuit, drop off Luc. Do not enter the Belle De Nuit. Instead, unlock all three Mayhem perks to unlock machine guns on the Aurora race car. The easiest way to unlock the last Mayhem perk is to find an open tank, hijack it, and destroy any Nazi vehicles that appear. Proceed to "The Race" where Sean is tasked with racing against Dierker in Saarbrucken. During the race, do not pass Dierker but get close enough to him to shoot his car with the machine guns on the Aurora. Continue shooting Dierker's car until it becomes damaged and the game credits appear, indicating that you have finished the game by killing Dierker. You can either wait until the credits end or skip them. After the credits, the "The Legend Begins" achievement or trophy will become unlocked, and a mission failed screen will appear, allowing you to retry the mission. Note: An open tank is located in the ruins of a building a few meters behind the church that sits at the top of the hill. The church is located behind the Belle De Nuit.

Steal a Nazi vehicle and put it in your garage. Blow it up. Take a new one from garage keeper and blow it again. Repeat that to complete 5 vehicle requirement for the Mad Bomber perk.

When you get then mission to knock out a large gun across the river from the Eiffel Tower, nearby on the same building is a smaller anti-aircraft gun. Eliminate all the guards nearby but leave the AA gun intact. When the mission is completed you can use the AA gun to shoot down Zeppelins. This will give you a level 5 alarm, which causes a series of airplanes to begin strafing you. Zeppelins earn $50 and planes $100 when shot down. The targets are unlimited, allowing you to get as much money as desired. To finish, jump off the building and die. When you return to HQ, you will have lost your weapons but have plenty of money to replace them. This can be repeated as many times as desired as long as the last AA gun remains.

Climb to the top of a building with an anti-aircraft gun and "liberate" the building without destroying that gun. Now take a position in the seat and you can rotate the turret to find zeppelins in the air. Make sure that you only rotate in one direction. As long as you do that, you'll keep finding more zeppelins and you can shoot them down for easy money.
