from on high trophy - easy way

[melodicmizery]

i dunno wtf the guide is talking about but you can easily do this trophy by going to fortuna, pick the lowest mission there is so the enemies are low rank, go into orb vallis (btw this is on venus) and jump on your k-drive and hit triangle to equip your secondary weapon and shoot people with it. thats all you have to do. you dont have to be in the plains. matter of fact this trick dont even work in the plains. youll need a kdrive anyways for some of the other trophies so after you get it this is how its done
