Neon Wings: Air Race

The game logic/algorithm for these achievements is broken, when you finish a race the game doesn't increment the progress, instead it just set the progress to the current value.

Target Locked can be done in tutorial level, you should track your progress with pen&paper or a phone, use combat log (bottom left) to confirm hit. Note that it doesn't count if your missile destroyed an enemy ship. Combat log should say "X DMG nickname ≫ enemy" for it to count. It is possible to get 6 hits per lap.

For Faster, you need 750 seconds of nitro skill. I'm not sure how many seconds you get per nitro skill, but I think 2–3 seconds is a safe assumption. The ship I use doesn't have any nitro upgrade when I'm doing this achievement.

Here's a video guide, sorry about the quality 😄
