This achievement is for completing the eighth mission of the game and can be obtained on any difficulty.
This is my playthrough of Mission 08 - Pipeline Destruction on normal.
Aircraft used: F-15E
Special weapon: 6AAM (6 air to air missiles)
Score required: First section 17,000 / second section 20 oil tankers (Normal)
Time limit: First section 5:00 / second section 10:00 (Normal)
For the first section I would suggest focusing on the oil tanks and the oil tanker ships to help you reach the target score of 17,000.
In the second section, make use of the map and expand it to it's largest size using the view button (the old back button). This will help you locate the 20 fleeing oil tankers in the sandstorm.Tip: I played through a couple of hours of multiplayer, gaining enough MRP (in game currency) to purchase the F-15E which made this a lot easier and more fun than the starting F-16C. Around Mission 12, I had enough to purchase the F-22A which is the most capable aircraft I've found so far. The currency, planes and most part upgrade unlocks work across multiplayer / singleplayer but some upgrades are exclusive to multiplayer. You can also go into 'Free Mission' to replay for some extra cash.
