The Megapithecus Arena itself is located beneath the blue Obelisk, but you can open the portal to the arena from any Obelisk or Supply Crate
The temperatures is really low, so having good Hypothermal protection such as Fur Armor is highly suggested. Consumables such Fria Curry, Shadow Steak Saute are recommend to be consumed before and during boss fight. More advanced players can also take advantage of Tek Canteen set in warm mode.

Broodmother Lysrix can also be challenged on The Center. The Center Arena appears to be an abandoned monastery worshipping the Megapithecus, as evidenced by various statues. The Arena is 6 °C or 42 °F So little Hypothermal protection is necessary. Entering the arena on The Center will also require the Megapithecus Tributes.
