To escape the prison cell in Metal Gear Solid Delta: Snake Eater, players can utilize the Fake Death Pill that the Boss placed in their leg wound. The first step involves picking up a fork within the cell to serve as a substitute for a knife, allowing you to extract the Fake Death Pill along with the transmitter from the wound. Once this is accomplished, you can use the Fake Death Pill to simulate your death when the guard approaches, prompting him to unlock the cell door for your escape.

Alternatively, players have a quicker option to detain their escape by tuning the radio to frequency 144.75, which unlocks the cell door immediately. This frequency is revealed in a secret first-person scene after undergoing the torture sequence at the hands of The Sorrow and The Boss. By employing one of these methods, players can successfully navigate their way out of the prison cell and continue their mission.
