Exo One

This achievement can be obtained easily if you know what you are doing and also unlocks the energy upgrade for this level if done properly. To do this you must fly to the small red arch found early on in the level.
To reach 'a great height' and the energy upgrade on the floating cube above you, you must travel to the front of the 'cannon' and glide into the sloped base of it. Upon hitting the sloped base in glide mode, you will begin travelling up the side of the structure. Keep moving upwards and you will be propelled straight upwards; keep gliding upwards and the achievement will eventually pop up.
