Though infamous for its less-than-perfect portrayals of women, the Metal Gear series has featured representations of queer characters, particularly Vamp from Metal Gear Solid 2: Sons of Liberty, who is bisexual.
In the 'Otacon' ending of Metal Gear Solid, Snake shares a romantic scene with Otacon instead of Meryl; however, this scene depicts a romantic-friendship confession more than an explicitly romantic resolution. It is referred to by fans as 'the gay ending' and can only be achieved by making an earlier decision that leads to Meryl's death.
Metal Gear Solid 3: Snake Eater features Volgin, an antagonist who makes unwanted advances towards both men and women.
In Metal Gear Solid: Peace Walker, there are 'dating sim' missions where Snake can date (and have implied sex with) Paz Ortega Andrade; however, you can also go on a date with Kaz Miller and take photos of him in his underwear.
In Metal Gear Solid 4: Guns of the Patriots Ocelot kisses Solid Snake. It is also implied in Metal Gear Solid V: The Phantom Pain that he had feelings for Big Boss, saying that he was 'in love with the legend'.
Dr. Strangelove—who appears in Metal Gear Solid: Peace Walker and The Phantom Pain—is implied to be bisexual, showing attraction for both men and women in the game. However, her plot primarily revolves around her dedicated to The Boss, a deceased woman.
