AI Lab

The AI Lab was a Mayan pyramid ruin used by the Peace Sentinels for developing the Mammal Pod (and presumably the other AI pods). It had a security gate that could allow people into the AI Lab via their ID Cards. However, Strangelove could block out those she does not favor from the security system even if they had their ID Card. It was apparently an undiscovered ruin or simply not even an actual ruin, as Paz implies that it was not a known ruin to the populace. It contained several supercomputers (comparable to a University lab) used to develop the AI pods, including the Mammal Pod, and apparently a prison, as Cecile was held in this area when she was captured by the Peace Sentinels. It also has several buildings besides the main pyramid.

History
Cecile travelled up to the AI Lab by accident when trying to record the calls of a Quetzal, and ended up recording one of the simulations of the Mammal Pod held by Dr. Strangelove, the Peace Sentinels' AI developer. She ended up captured shortly thereafter. She later managed to escape and caught a brief glimpse of the AI lab's interior before making it out of the AI Lab and escaping using a stolen film badge.

Big Boss later attempted to enter this area to shut down the Mammal Pod, in order to halt Peace Walker's production. He attempted to use Huey's ID Card, but it failed to work due to Strangelove blocking out his identity from the security system. Big Boss then proceeded to disarm a CIA mercenary who stole Cecile's card and used that to enter the AI Lab. He attempted, upon being goaded by Strangelove, who bore a grudge against Big Boss for killing The Boss ten years prior, to eliminate the Mammal Pod, but he ended up passing out due to the shock of The Boss's haunting voice from the Mammal Pod. He woke up outside the AI Lab shortly thereafter only to discover that the Peace Sentinels had already managed to transport the Mammal Pod away, and also had to contend to the Chrysalis AI weapon, and then decommissioning it.
