10 Saddest Video Game Endings Of All Time
4. Metal Gear Solid 3: Snake Eater
The final battle in MGS3 is sad enough, with Snake forced to kill his former friend and future namesake, The Boss. With her death comes the truth that she never betrayed her country, but was sent to recover The Legacy, a massive war fund originally setup by The Philosophers.
Yet, once Volgin fired the nuke, she knew she had to sacrifice her reputation in order to protect the reputation of the USA and prevent World War 3. As Snake inherits the title of Big Boss, he becomes disgusted with how the USA betrays its greatest hero, and we see the beginnings of Militaires Sans Frontières as he stands over The Boss' grave and salutes.
The Boss' sacrifice for peace leads to Zero and Big Boss forming The Patriots, which in time become corrupted. Zero creates the AI systems that control the world and fund the war economy, while Big Boss becomes too enraptured in his ideal of freeing soldiers from government abuse, eventually forming terrorist nation, Outer Heaven.
All in all, not the legacy she was hoping for.
