Always do level 3 beacuse doing all 3 is a wast of resources and if you beat level 3 you get the rewards for level 1 and 2 also.

Bring lots of megatheriums, they have a damage boost against bugs, wait, spiders are bugs right? RIGHT?!?! Oh and two mate boosted yutyranuses. And rex's.

I went in with two Daeodons eight megatheriums a yutyrannus and one megalania to kill the alpha version. I climbed to the ceiling of the cave with the megalania and blasted it with rockets from the roof while the megatherium tanked it and the yuty gave the Megas a buff and the daeodon healed

You can kill it in about 15 seconds with a high wooly rhino and alot of health and damage with vegie cakes

All you need is a dodo and a slingshot I mean really cmon guys

The best team in my opinion (this goes for the gorilla boss as well) is 15 rexes, 2 yutys, and 3 daeodons. If you can't get your hands on all 15 rexes, megatheriums work just as well bc of their buff when they kill bugs. When they kill a spider minion, they get a damadge buff, helping them defeat the broodmother. Do not use them for the gorilla boss, just use allos instead.

14-15 boss rexes and 1 Yuty. For the rexes I recommend stats to be . . 25k+ Health, 560+ melee dmg. For the Yuty I recommend . . 10k+ health , 3450+ Stm , 110 movement speed, 100% imprint. I usually ride the Yuty while my tribe rides the Rex. Those stats usually work. Never had a rex die. Usually takes about 5 min to beat boss. Once completed we owl heal all of our dinos and rerun the boss fight 3-4 times after. We get a lot of element and Ingot because some people like to buy a seat.

Use Megatherium for the Broodmother because they get a HUGE boost for killing insects and spiders.

Use mutated megatherium

Megatheriums are great due to the buff. They also kill the minions instantly

I take a variation of Dino’s with high health and melee usually about ten or so bosses get destroyed pretty easy about 15 sec or less

Is anyone else having a issue battling her...once the countdown completes I'm falling from way above the earth and just splatter at the bottom. I have survived a few times but as soon as I got her she batted into the unknowns of the ark never to be found.

Bring 10 Rex’s 2 yutys 3 pigs all your friends and 5 bug killers

I was on single player, did all the official work necessary to face the alpha version. Just to make it interesting I spawned a lvl 1500 rex.... she still took it down. R.I.P. Rexy.
