While playing Metal Gear Solid Delta: Snake Eater, you’re going to see that Eva was waiting for someone named Adam. So was Snake, but he was ambushed by someone named Revolver Ocelot.
Ocelot has his own unit and is known for his signature ricochet shots with his revolver. But as the game goes on, you find out there’s a lot more to him than meets the eye. Since Delta is doing the same story as Snake Eater, if you payed attention, you can find the answer in the original.
The True Identity of Adam in Metal Gear Solid Delta

The big revelation is that Revolver Ocelot is actually a triple agent, working for the KGB and the CIA, all while secretly reporting to a shadowy group known as the Philosophers. His real name is Adamska, and he’s the illegitimate son of The Boss and another legendary soldier. This is where his codename “ADAM” comes in.
The name isn’t just a random choice; it’s a cover identity he used as an NSA code breaker who “defected” to the Soviet Union. The name also means “the ground” or “earth” in Hebrew, which is a nod to his birth on the battlefield and his deep roots in the saga.
In the game, Snake is told to meet with a Soviet spy named ADAM, but he ends up meeting a woman named EVA who claims to be the contact. The whole time, Revolver Ocelot is operating behind the scenes, playing his part as a triple agent and setting the stage for events that will shape the entire Metal Gear universe.
The post-credits scene in the original game reveals Ocelot was the real ADAM all along, and that he was manipulating the entire mission to serve his own, and later Big Boss’s, goals. It’s a classic example of Ocelot’s strategic brilliance and his willingness to manipulate any situation to his advantage. This has a lot to do with the lore of the series, so it will likely never be changed or retconned.
How Eva and Ocelot Played Adam During Operation Snake Eater

When Naked Snake went on his mission to infiltrate the Soviet Union in Operation Snake Eater, he was supposed to meet up with a contact named ADAM, but he actually ended up meeting two different people, EVA and Ocelot, who were both playing the role of “Adam” in their own way. It’s a classic spy story double-cross, but with a twist because they were both helping him, just for completely different reasons.
Ocelot, whose real name was Adamska, was introduced as a GRU Major and the leader of the Ocelot Unit, and he was an instant rival to Snake. What Snake didn’t know was that Ocelot was a double agent, or maybe a triple agent, who was secretly working for the CIA and the future Patriots. His whole defection to the Soviet Union was just a cover so he could infiltrate and gather intel.
Ocelot’s role as “Adam” was all about manipulation. He played the character of a rival, challenging Snake to duels and even giving him advice on how to use revolvers. This wasn’t just for kicks; it was all part of a larger plan to shape Snake and serve the Patriots’ vision. He was pulling the strings from the inside, making sure events played out just the way he wanted them to, all while pretending to be an enemy.
Then you have EVA, who was the second person to assume the “Adam” role. Her mission was to secure the Philosophers’ Legacy, but not for the Soviets. She was actually an agent for the Chinese People’s Liberation Army. EVA pretended to be the KGB operative Tatyana and Nikolai Sokolov’s lover to get close to Volgin and get information about the Shagohod and the Legacy.
She was a master of deception, using her charm and intelligence to gain Volgin’s trust while secretly providing Snake with crucial intelligence and support. Her interactions with Snake were genuine, but she was still using her role as an ally to get the Legacy for her own purposes.
