I finally got it. Here's a mini-guide for anyone else trying to get the
Evasive achievement in Lunar Flight:
The achievement itself is fairly simple. In order to get it, all you have to do is to decieve a homing missile thrown at you using a flare (Right Ctrl by default). However, in order to do this, another player must lock his missiles on you, which is kinda tricky.
In order to throw a homing missile at someone, you have to:
- Press the TGT button on the map
- Keep pressing the NEXT button on the map until you choose a human target
- Go to his position and face him/her. Use the lower compass as a guide
- Once the distance between you and him/her is lower than 200m, after a couple of seconds a crosshair will appear
- Throw a missile pressing Right Shift (by default)
I couldn't find anything on this, not even on the game's manual. I figured it out with some guy, and once you know what you have to do you will get it after a couple of attempts.
