Once at the arena, BE CAREFULL AS HELL THAT YOU AND YOUR TAMES DO NOT, NOT, NOT FALL INTO THE HOLE AT THE RIGHT. YOU AND YOUR TAMES WILL DIE IF THEY FALL IN, OR YOU DO. Quicky get all your dinos in the fighting arena, as the boss has knock back damage. Fight at beta difficulty.
Make sure that you move your Rexs or creatures into the trees when you get teleported into the arena. This is to prevent your tames from falling into the hole in the arena, because if they fall they just die, and you lose the saddles and everything. Then you can go up on your yuty or whatever you are riding and you lead the Megapithicus to your tames, then let them go ham on the monkey. The Megapithicus is a glass cannon and anything g with a good saddle and a high health stat can easily destroy it. Just make sure that nothing falls into the death hole and you’ll be fine to actually fight the boss.
The megapithecus has two attacks a direct hit attack and a ranged Boulder attack. The boulder attack can and will kill you off your tame and I figured this out the hard way.so safest thing is to wistle attack Target hope off and have someone roar the Yuri good luck survivors.
To battle the megapithecus, I would suggest using a pack of allos,a yutyrannus, and a daeodon. The reason I pick these creatures are because that first of all, allos in a pack are dangerous, and one of them will be boosted as the alpha, and the other allos will also be stronger. Second, yutyrannus’s can scare away the minions the boss summons, and can make the creatures deal more damage. I also HIGHLY request a daeodon because they can heal your Dino’s, and itself durning battle, just make sure it has enough meat to last the battle. This method will work with any boss on the island DLC, not the overseer, but I used this method on the broodmother,megapithecus, and dragon, and it worked perfectly.
Hardest part about this boss on The Island is getting the Spino sails for the alpha summoning. Spinos don't like to spawn on this map (FYI they are water spawns so kill fish to try to get them to spawn in) and I had to go to Crystal isles and transfer a few stacks over. He's a pushover and a glass cannon. Just avoid the pit falls in the arena and bring him to your tames in the trees and swarm him with theris or rexes while you ride a screaming yuti and he goes down really fast.
This boss really isn’t that hard. All you need for yourself is mastercraft or ascendant assault rifle (journeyman will do, but Isn’t as good). Then, to deal with his minions,get 4-5 high level troodons, because they will absolutely WRECK the minions. As tanks, Rexes are, of course, nessecary. And to keep yourself out of trouble, get a fast but durable mount, like an allo or a really high level raptor. Hope this helps!
For anyone who thinks this is just as hard as the other bosses, it’s not. It’s the easiest boss in the whole game and I easily killed the gamma with my rexes (35k health and 450-550 melee) and got it down fast. DON’T be afraid. If you enjoyed like so scared people can see
This is just my opinion, but I feel it is much easier to get on your yutyrannus and try to bring the megapithecus to your tames instead of doing the opposite. The pit on the right of the bridge will instantly kill your Dino’s and you if you are not careful. I just find it easier. Up for more :)
If you really want to go overboard bring in max dino cap (20 is Max) with at least 17 Rex's and 3 yutyranus. This will obviously increase your chances of killing it, try to level your Rex's in health way more than melee considering you have the yutyranus buff already assisting you or you can go full melee for a glass cannon run. Be aware that this may have a huge risk to it though if you don't have more than MINUMUM 10K health ON HATCH you may or may not die depending on your saddles and or melee damage. Don't forget the rock throw can kill you off of your mount so spread yourselves out if you aren't going to dismount. Otherwise whistle attack target and only mount the yutyranus for the empowerment of the Rex's. The rest of you bring compound bows, snipers, fab pistols, rocket launchers etc. You will also need some focal chilli to increase your chances of survival. Good luck :)
Don’t forget your common sense me and my friends had everything and we were ready. Weapons creatures everything. Except fur gear. Yes we forgot the most important thing and we almost died luckily for us we had tek canteens so we switched them to hot and let our creatures distinct everything while we got hot water it helps helped but it almost wasent enough somehow we won
Instead of trash force tame tips why don’t I give you some useful info that you can put into practice.
On official smalltribes I went in with 3 rexes one yuty and a deinonychus. I failed. I didn’t fall down the hole or anything, I simply didn’t have enough firepower.
Forget rexes, unless you want them to tank the boss. The Dino you need for bosses is the deinonychus. As fake as it sounds you can beat it on official with even ONE deinonychus. The reason it can destroy the boss and basically any other boss is because they are the only Dino in the game that does bleed damage to bosses. Bring multiple deinonychus, have some hiding away from the action as a backup because if you bring one and it dies then you lose. I am going to be fighting it again but this time with a pack of deinonychus and 2 stegos (mateboosted) to tank while I do the killing. Search it up on YouTube, Rex’s aren’t the way anymore it’s deinonychus, those feathery raptors, on valguero and fjordur. Also you can easily get artifacts you need for gamma in crystal isles, you legit just need 3 artifacts and you are in. Make sure your deinonychus is a very high level and give it very good health and Stam if you like. Good luck boys.
Take a male and female gigantopithecus mackerel them breed them do the same again mackerel the babies breed them repeat about 8 times then take the final end product put it in a good hat and go kill this boss!
Before entering the arena take your creatures out of their cryopods (if you use them) because you can't use cryopods in the fight. I found this out the hard way and almost lost all of my boss fighting Dino's. Fortunately if you need to escape the fight once it's started you can leave the game and rejoin and it will place you and your tames at the obelisk (doesn't give summon items back).
