These are great tames and they are decently early game. If you want to tame one easily get the upgrade station mod and make a torch, then upgrade it until you get at least five hundred damage on it that will deal about 230 torpor per hit. After that now find the desired megaraptor. Now go to the megaraptor alter and challenge the megaraptor. The alter is a spike in the ground with a few bones around the bottom. When you are in the minigame a thick fog will arise and you will not see the megaraptor. Look side to side constantly. The megaraptor will attack you once and then retreat then it will attack again. Be prepared and bring 3 sets of flak. They are an exceptional kibble tame. The megaraptor has a double jump, it has mid speed, and it is slightly bigger than a carno. Hope you successfully tame your megaraptor
