After you blow up the fuel depot at the start of the game and retur to the Belle De Nuit, drop off Luc. Instead of entering the Belle De Nuit, 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 may either wait until the credits end or skip them. After the credits, the "The Legend Begins" achievement 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.
The following vehicles can be found in the corresponding locations:
VEHICLE - LOCATION Bauer Fuel Truck - West Picardie/North Normadie. Near the river, where the road the road hooks around. Gestapo GS - Gare Saint Lazarre. It's parked North of the checkpoint near the tower with the propaganda speaker. Armed ZP750 - Raise the alarm level to get it. Gestapo Cruiser (Not GS) - On streets around Nazi areas.
To easily earn money at the mission where you have to destroy the large gun across the river from the Eiffel tower, go to where the Anti-Aircraft gun is located and take out all the guards. After completing the mission, use the AA gun to shoot down the Zeppelins. You will earn $50 for shooting down each Zeppelin. Shooting down the Zeppelins will raise your alarm level to 5 and cause airplanes to strafe you. You will earn $100 for each airplane that you shoot down. The Zeppelins and Aircraft will continuously respawn allowing you to earn as much money as desired. Once you are done, either save the game and reload it or jump off the building and die. You will however lose your weapons, but can use the money earned to replace them.
