Konami has announced that Metal Gear Solid Delta: Snake Eater will feature the return of the beloved and quirky Secret Theater bonus feature from Snake Eater. This side of the series, known for its humorous and fantastical take on the game’s cutscenes, was originally created as an Easter egg for the production team but eventually gained popularity among fans.
The new Secret Theater videos will be available to players by tracking down enemy soldiers carrying rolls of film on their uniforms, a nod to the original feature. In addition to the classic cutscenes from Snake Eater, new ones have been created exclusively for this collection.
Metal Gear Solid Delta: Snake Eater will also include several other extras, including an online multiplayer mode called Fox Hunt, an Ape Escape crossover on PC and PS5, and a unique Snake vs. Bomberman mode exclusive to the Xbox Series X|S version of the game. The game is set to launch on August 28 for various platforms.
