How to unlock the Energy Attack achievement in Heroes Over Europe - Definitive Guide
I'm not quite sure what 'full speed' is, but if the edges of your screen are blurred, and you kill one of the bombers on the way down, you stand a 99% chance of unlocking this achievement!
Could well be the first achievement that you unlock; 'twas mine!
Diving at full throttle from high above enemy planes allows you to inflict massive damage. Ascend as high as possible to give you more time to get up to speed and kill the enemy. Time your dive so that the enemy is almost directly under you when you're diving straight down. Watch for the speed line indicators around the reticule before firing. The speed lines will look like sun rays coming from your targeting reticule.
This is easier to do on lower difficulties. A good place to attempt this trophy is towards the beginning of mission 1, Phoney War where you have the slow moving group of Ju 88 A-4 bombers. Choosing a plane with machine guns may help as well, since machine guns don't overheat as quickly as cannons. If you're having a lot of trouble with this trophy, use a plane with an automated rear gunner such as the P-61 Black Widow.
