Out of this Dimension (Star Fox)
This side quest is unique from the others on this list, in the sense that it requires a serious level of commitment that potentially jeopardizes the lives of everyone in the Lylat galaxy. To access it, players will have to pelt a particularly large asteroid with laser fire until a gigantic bird emerges from it. Crashing your ship into this bird will warp you directly to Out of this Dimension, which sounds a lot like a space-themed Pizza Hut promotion.
Here, you will be taken to Fox McCloud’s worst fever dream: a bizarre expanse of space with paper airplanes and asteroids brandishing perverted grins. The wicked boss of this cursed land is a giant slot machine, and it is defeated when it yields three 7s. Your victory will be celebrated with a shower of useless coins, and the credits will begin to roll. From there, you can shoot the jumbled letters onscreen until they spell out THE END, and… that’s it. That’s the fate of the Star Fox team.
The fact that you can only free yourself from this endless torment is by turning off the console, plus General Pepper’s final desperate message – “Come in, Arwings!! Fox, where are you?!! We need you to protect Corneria!!” – make this a harrowing alternate ending. Nobody left to stop the tyrannical advances of the Venom army, and an eternity spent in a vacuum of space with Slippy Toad. Tragic.
