Chozo Lord Video, Spankyyy
Me Video, AmazingBowler30
Also x LeGeNd ShadOw has a great Seriously 3.0 guide on all of the medals here!
My own list for the Hardest medals to boost :
Skunker, Bcuz you only get 1 every two rounds you win.
Weapon kills, Bcuz you can't Ideal boost them, And theirs to many of them, 6000 kills to onyx each -_-
except Pyro, Old schooler, Captor.
Superme AllFather, AKA all 6 Game modes, Takes time but not as hard as Weapons kills.
None, all horde medals are easy to get.
HIGH ROLLER, Never played beast after i Onyxed this medal.
FORCE MULTIPLIER, Never played Arcade after i Onyxed this medal.
